Abstract

References to Terebratulina caputserpentis attributing its authorship to Zbyszewski, 1957, not to Linnæus, 1767, have been found in three recent publications, in the collections of the Muséum National d'Histoire naturelle de Paris and in several online databases. The use in these databases seems to have arisen from WoRMS (World Register of Marine Species), specifically from WBD (World Brachiopoda Database) of which the three authors of this paper are the editors (authors). The page concerning T. caputserpentis (Linnæus, 1767) has been modified by WoRMS staff without the knowledge of these editors (authors).

The decrease of the specialists in systematics and their replacement by IT specialists question the scientific reliability of the online databases as well as the specimen labelling in museums. The absence of scientific rigour becomes their Achilles' heel. Several other cases of errors are quoted and developed. In spite of applications to the staff of databases in biodiversity, the situation continued degrading so much so that today these bases are reached by the Peter principle and can no longer be used for scientific requirements, except if verifying all the desired data.

1. Introduction

The decrease of specialists in systematics and their replacement by IT specialists question the scientific reliability of the online databases as well as the specimen labelling in museums. The absence of scientific rigour becomes their Achilles' heel. In spite of applications to the staff of databases in biodiversity, the situation continued degrading so much so that today these bases are an example of the Peter principle (Peter & Hull, 1969) and can no longer be used for scientific requirements, except if verifying all the desired data. An example of the above is the recent use of the terebratulid species Terebratulina caputserpentis in several online databases.

References to Terebratulina caputserpentis attributing its authorship to Zbyszewski, 1957, and not to Linnæus, 1758 who first published the name caputserpentis as Anomia caputserpentis in accordance with the criteria of availability (ICZN, 1999, Articles 10 to 20, see also Article 50) have been found by the present authors in three recent publications. This inerrant attribution is also in the collections of the Muséum National d'Histoire naturelle de Paris and what could be more problematical, in several online databases. The missuse in these databases seems to have arisen from WoRMS (World Register of Marine Species), to be precise from WBD (World Brachiopoda Database) of which the three authors of this paper are the editors (authors). The page concerning T. caputserpentis (Linnæus, 1767) has been modified by WoRMS staff without the knowledge of these editors (authors).

Using several search engines to try to identify the original citation of Terebratulina caputserpentis with Zbyszewski (1957) as author, the result led surprisingly to two databases WoRMS (our own!) and GBIF. Other databases, i.e., Catalogue of Life, Taxonomicon, which for years linked to WoRMS for brachiopods, have reiterated the error.

Checking our World Brachiopoda Database (WBD) on WoRMS, we discovered a page on "Terebratulina caputserpentis (Zbyszewski, 1957)" (sic) as a synonym of T. retusa. The editors would never have published such a page (see in the section below quotation on their papers on these species). How did this happen? Only the staff of WoRMS has access to our database and could modify the page probably by changing the author's name. This is not the first case of changes in the database by the staff without agreement of the editors. Several other examples occurred recently, like the tropical brachiopod Lingula anatina recorded in the UK waters, which is incorrectly recorded in MSBIAS (Marine Species of the British Isles and Adjacent Seas), a database hosted by VLIZ (Vlaams Instituut voor de Zee, Belgium) as is similar to our WoRMS database. These facts call into question the scientific content of WoRMS pages, unwittingly but obviously the credibility of the editors and the reliability of WoRMS and more broadly of all databases with scientific contents.

Regarding the GBIF (Global Biodiversity Information Facility), the analysis of the results is more complex. The so-called "Terebratulina caputserpentis (Zbyszewski, 1957)" appears to be the only synonym, and the priority attribution of T. caputserpentis (Linnæus, 1767) is not listed. Of the 18 "occurrences" provided in this database for the "species" "Terebratulina caputserpentis (Zbyszewski, 1957)" we consider worth adding the following comments. About its location: South Africa (n° 477223472): from Agulhas Bank, Challenger Expedition, we believe that this "occurrence" is based on Davidson (1880, p. 12; 1886, p. 36 and Pl. VII, figs. 1-5), who described and illustrated specimens of Terebratulina (Agulhasia) davidsoni King, 1871 (now Agulhasia davidsoni King, 1871; see Logan, 2007, p. 3099 and papers cited therein), not Terebratulina caput-serpentis as quoted in GBIF. Moreover, Terebratulina caput-serpentis var. septentrionalis recorded (described and illustrated) off the Cape of Good Hope by Davidson (1880, p. 13, 33; 1886, p. 38, 70 and Pl. V, fig. 54) [now Terebratulina abyssicola (Adams & Reeve, 1850); see also Logan, 2007, p. 3098 and papers cited therein] is listed in GBIF under T. caputserpentis Zbyszewski and not T. abyssicola. Regarding the locations "Norway, United Kingdom" it should be noted that all known "Terebratulina" records in these areas are related to T. retusa not to "Terebratulina caputserpentis (Zbyszewski, 1957)" (see Brunton & Curry, 1979, p. 38; Cohen et al., 1991, 1993; Álvarez & Emig, 2005, p. 139; Logan, 2007, p. 3098; Álvarez, 2016, and papers cited therein). Regarding the occurrences "Canada" and "Italy", it should be noted that only T. septentrionalis (Couthouy, 1838) has been recorded in Canada and that only T. retusa occurs in the Mediterranean, as both living and fossil forms (e.g., Brunton & Curry, 1979, p. 38; Álvarez & Emig, 2005, p. 139; Logan, 2007, p. 3098; Emig, 2016, and papers cited therein).

2. Present status of the species Anomia caputserpentis and A. retusa

The species name retusa was first used as a valid binomial by Linnæus in his description of Anomia retusa in the tenth edition of the Systema Naturae (1758, p. 701, number 191) with the following description: "A. texta ovovata striata retusa: convalle longitudinali, nate perforata" and the comment: "Habitat in pelago Norvegico supra Alcyonia. D. Pennant." Although in this occasion, no illustration, or reference to a previous illustration was provided, from the description given it is clear that to Linnæus "retusa" was a strongly ribbed living species.

In the same edition, Linnæus erected the species Anomia caputserpentis (1758, p. 703, number 200). Under "Caputserpentis. 200." Linnæus gave a brief description: "A. texta ovovata laevi gibba: valvula altera apice longiore" and the observation: "Habitat ... fossilis. Natium altera postice gibba, perforata." Linnæus gave no illustration, but referred to "Column. purp. 22. f. 2." Colonna's work (Colonna, 1616; Fabio Colonna = Fabius Columna = Fabij Columnae) was commented and the illustration reproduced by Lee et al. (2001, p. 84-85, 92-93, and Fig. 1 respectively; see also Muir-Wood, 1955, Fig. 2). On p. 85, Lee et al. (2001) pointed out that "the two upper brachiopods in the Colonna figure are both smooth terebratulid brachiopods with large open foramens and strongly delineated growth bands." Across the two drawings on the upper right and upper left of Colonna's page 22 is the caption "concha anomia vertice rostrato". Lee et al. (2001, p. 26) stated that Colonna himself regarded both specimens, those in the upper right and upper left "similar to one another". To these authors (Lee et al., 2001, p. 86) the smooth, unfolded specimen on the upper right on page 22 [the specimen that Linnæus (1758, p. 703) described as Anomia caputserpentis] "certainly came from Pliocene strata near Andria" while the specimen illustrated on the upper left on page 22 [the specimen that Linnæus (1758, p. 703) described as Anomia terebratula] although from an unknown locality, the sediment contained in its interior (see also Colonna, 1616, p. 24) allowed Lee et al. (2001, p. 86) to suppose that this specimen "was collected from the same Pliocene calcarenites at Andria", an inland town west of Bari. Although there is no scale on the illustration, the brachiopod on the upper right (Anomia caputserpentis) is at natural size (-icon magnitudinem aequat- on page 23 in Purpura). A very important issue for the case we are discussing in this paper, we want to stress what Lee et al. (2001, p. 86) concluded when referring to the strongly folded and the unfolded specimens illustrated on Colonna (1616) that "From the many specimens of Terebratula collected by the authors [Lee et al.] from Colonna's Andria locality and from elsewhere in Italy, it is apparent that the brachiopods in any fossil assemblage/population vary considerably in the degree of folding and may be rectimarginate to biplicate or suciplicate. Thus, both specimens labelled by Colonna as Concha anomia vertice rostrate are species of Terebratula (sensu lato), and given the wide variation in populations of Neogene Terebratula, might be conspecific." In fact, a few years before, Hanley (1855, p. 123; see also Thomson, 1927, p. 186) already stated that: "the name Anomia caputserpentis Linnæus, 1758 (p. 703) was applied to a fossil smooth Terebratuloid, most likely from the Italian Tertiary" (see discussion on its locality in Brunton & Cocks in Brunton et al., 1967, p. 174-175; Bergström & Hageltorn, 1968, p. 111-128; Lee et al., 2001, p. 86). According to a strict application of the rules of nomenclature, Thomson (1927, p. 186) stated that "Terebratulina with type Anomia caput-serpentis Linné would have to be used for a smooth Terebratuloid, and presumably would become a synonym of Terebratula"; although he also warned that: "this method of interpretation is not accepted by many authors, and not good purpose would be served by applying it to the present case".

Significant ambiguities arose soon after, when Linnæus in the twelfth edition of the Systema (1767) changed his previous description of Anomia caputserpentis to "A testa obovata striata tomentosa: valvula altera nate longiore perforata. Fn. suec. 2154. Column. purp. 22.f.2. Gualt. test.t. 96.f. D. Hiatat in abysso M. Norvegici. Testa obovata, tomentoso, antice compressa, longitudinaliter striata, alba. Valvula superior postice prominens logiorque apice perforato ligamento affixo coralliis Zoophytisve; haec antice paulo longior & declinata. Inferior valvula rotundata, antice retusa, postice brevior. Margo utriuque crenulatus. Cardo dente utriusque testae utrinque ad latus prominens", while that of A. retusa remained. Thus, as Brunton & Cocks (1967, p. 294) stated, "in the 1767 edition these two species, A. caputserpentis and A. retusa, appear to be indistinguishable and this change in concept of A. caputserpentis has resulted in ambiguity."

A further complication emerged when Orbigny (1847, p. 249) erected the genus Terebratulina with Anomia caputserpentis Linnæus as type species. Orbigny clearly thought of this as the species as redefined in 1767, the species subsequently considered as synonymous with Anomia retusa (see discussion in Brunton & Cocks, 1967, p. 295).

Later, Davidson (1886) pointed out that "no species of Brachiopoda has been more thoroughly or more carefully studied than the Anomia caput-serpentis of Linnæus [1767, p. 1153]." He considered Anomia retusa of Linnæus (1767, p. 1151) as synonymous of Terebratulina caputserpentis which has been recorded in many Tertiary outcrops in Europe. This synonymy has been confirmed by Hanley (1855, p. 123) at least for the Recent ribbed specimens, in his book on the shells of Linnæus. Dall (1920; see also Thomson, 1927, p. 186) has pointed out that "Terebratulina caputserpentis should be known by the specific name retusa described under Anomia retusa by Linnæus (1758, p. 701) which has page precedence over Anomia caput-serpentis Linné 1758, p. 1758." Most subsequent authors (e.g., Hanley, 1855, p. 123; Davidson, 1886, p. 17; Dall, 1920, p. 296; but not for example Œhlert, 1887 [*], Fischer & Œhlert, 1891, p. 29) have recognised that A. caputserpentis Linnæus, 1767, is synonymous with A. retusa Linnæus, 1758. More recently, Brunton & Cocks (1967; see also Brunton & Cocks in Brunton et al., 1967, and Lee et al., 2001) discussed in detail the ambiguities that arose when Linnæus (1767) changed this description of A. caputserpentis from a smooth, fossil brachiopod to a capillate [*] living species (now Terebratulina retusa), although he retained the reference to the Colonna figure. To solve this ambiguities Brunton & Cocks (1967) sent an application to the International Commission on Zoological Nomenclature (Ruling of the Commission, 1968) stating that "it is generally agreed that Anomia caputserpentis Linnæus, 1758, is not of the genus Terebratulina d'Orbigny; A. caputserpentis Linnæus, 1767 = A. retusa Linnæus, 1758; and that d'Orbigny's original concept of the genus Terebratulina is based upon the living species A. caputserpentis Linnæus, 1767 [non 1758] which is the junior synonym of A. retusa Linnæus." Brunton & Cocks (1967, p. 295) proposed also "that the type-species of Terebratulina d'Orbigny, 1847, be changed from Anomia caputserpentis Linnæus, 1758, to Anomia retusa Linnæus, 1758." In fact, nowadays no brachiopod specialist would discuss this authorship and synonymy: Anomia retusa Linnæus, 1758 = A. caputserpentis Linnæus, 1767 as type species of Terebratulina Orbigny, 1847 (see, for example, Álvarez, 2016; Álvarez & Emig, 2005; Bitner & Dulai, 2008; Bitner et al., 2008; Brunton & Cocks, 1967 and in Brunton et al., 1967 [*]; Emig, 2010, 2012, 2014, 2016; Emig et al., 2015; Lee et al., 2001, 2006; Paknevitch et al., 2013; Taddei Ruggiero & Bitner, 2008). Finally, it should be noted that T. retusa is well known in Europe since the Miocene, in particular in the Mediterranean realm and largely distributed today in the Mediterranean Sea and that many Holocene and Tertiary species formerly placed under Anomia and/or Terebratulina have been transferred to Terebratula, Dyscolia, Chlidonophora, Eucalathis, Murravia or Cancellothyris (see Thomson, 1927, p. 187; Lee et al., 2001, p. 89; Treatise on Invertebrate Paleontology, 1997-2007).

3. Discussion

Although the authorship of both Terebratulina species, retusa and caputserpentis are well clarified (see text above), specimens identified as Terebratulina caputserpentis appeared at least in three recent papers with Zbyszewski (1957) [not Linnæus (1758)] as author. For example, Estevens et al. (1999) quoted this species in the Miocene of the peninsula of Setúbal with reference to Zbyszewski (1957). Later, González Álvarez (2013) identified Terebratulina caputserpentis again with Zbyszewski, 1957, as author, in the Miocene of the Eastern Canary Islands, from a dorsal valve, partially broken. González Álvarez (2013) stated that this species is considered to be synonymous with T. retusa (Linnæus, 1758) and in addition cited the list of synonyms published by Emig (2012, not 2002 as stated by the author): "caputserpentis" is mentioned several times, i.e., Anomia caputserpentis Linnæus, 1767 (its original name), and Terebratulina caputserpentis Orbigny, 1847. Surprisingly, the publication of Zbyszewski (1957) is not cited. Of course only the valid species name T. retusa, with Linnæus, 1758 had to be used when referring to the well ribbed terebratuloid described by Linnæus (1758, p. 701; 1767, p. 1151 and 1153). More recently, in 2014, in a congress poster, González et al. figured Terebratulina caputserpentis, again with Zbyszewski (1957) as author, recorded from the Mio-Pliocene of the Canary Islands.

Besides these citations, in the collection of the Muséum National d'Histoire naturelle de Paris, specimens are identified as "Terebratulina caputserpentis (Zbyszewski, 1957)" (sic) and others as "T. caputserpentis (Linnæus, 1758)" – not 1767! – and online it is stated "Le nom d'espèce Terebratulina caputserpentis pourrait présenter un cas d'homonymie." According to Pierre Lozouet, curator of invertebrates conservation at the Museum (pers. comm., 2015), the specimens arrived in the Museum in 1969, belonging to the collection Staadt, a great collector of molluscs: it was labelled "V. Demange May 1931", and on another label the origin of the record "Siacca Italie" on the back in another script "Terebratulina caputserpentis Zbyszewski". Some years ago, during the computerization of the collections, the name "Zbyszewski (1957)" was erroneously introduced as species author. These specimens are now referred to WoRMS n° [AphiaID: 181482].

From all written above, we realize some zoologists and/or palaeontologists, professionals or amateurs, do not consult the Code adopted by the International Commission on Zoological Nomenclature (ICZN, 1999), and so do not follow the mandatory provisions and recommendations when writing their manuscripts submitted to journals or contributions to different symposia, and later incorporate in databases without the supervision of specialists in systematics. This is especially important when these studies are carried out by people unfamiliar with the taxonomy and the detailed morphology of many of the taxa involved (see discussion in Álvarez et al., 2010, p. 28). For the species we are using here as example of the scientific errors induced by database manipulations and its consequences, Article 50 of ICZN (1999) entitled "Authors of names and nomenclatural acts" is very clear when stating that "The author of a name or nomenclatural act is the person who first publishes it [Arts. 8, 11] in a way that satisfies de criteria of availability [Arts. 10 to 20]...". Following these mandatory provisions it is clear that Linnæus is the author to which the species Anomia retusa and A. caputsepentis must be attributed [Linnæus, 1758, p. 701, and p. 703 respectively]. The three Linnæus species, Anomia retusa Linnæus, 1758 (p. 701), A. pubescens Linnæus, 1767 (p. 1153), and A. caputsepentis, as described by Linnæus (1767, p. 1153) (non Linnæus, 1758, p. 703), are considered synonyms (see ICZN, 1999, p. 117-118, and Brunton & Cocks in Brunton et al., 1967, p. 174-175).

4. Conclusions

A taxonomist judgement or references to previous work for a given taxon are obviously needed to confirm the taxon identification. The bibliographic knowledge about the quoted material is needed to manage a database. Thus, Terebratulina caputserpentis should never have been cited with "(Zbyszewski, 1957)" as author (only in synonymy lists), because Linnæus (1767, p. 1153) was the first person who published the name caputserpentis satisfying the criteria of availability and priority. In addition Terebratulina caputserpentis (Linnæus, 1767) is, since Dall (1920), a work of reference in present brachiopod taxonomy), commonly if not always listed in the synonymy list of Terebratulina retusa (Linnæus, 1758) (e.g., Brunton & Cocks in Brunton et al., 1967, p. 175). Any researcher working on this phylum knows that it is useful to peruse the Treatise on Invertebrate Paleontology (1st edition 1965, 2nd edition 1997-2007), which was an omission in the works of Estevens et al. (1999), González Álvarez (2013), and González et al. (2014).

More and more databases, but also museums, no longer have systematicians available to confirm the identification of their cited or curated taxa. The drastic reduction of taxonomists, so-called morphologists, is currently due to their non-replacement after retirement. It is a political will, at least in the European Union, partly supported by scientific disciplines, such as geneticians and molecularists. This situation is not new and has even been widely anticipated. At the first International Congress on brachiopods in Brest in 1985, the organizing committee proposed the revision of brachiopod systematic (Emig & Rachebœuf, 1986), expecting that in 20 years, such a task could not bring together all the necessary specialists to revise the brachiopods. The 2nd edition of Part H of the Treatise on Invertebrate Paleontology (1997-2007) was the result. Today the rational of this visionary project is evident.

WoRMS remains the only global database to bring together a large panel of scientists who have skills to ensure the taxonomic relevance and excellence in systematics. Yet this specificity, recognized worldwide, is only weakly supported by WoRMS management staff. Because requests from scientific editors to set stricter scientific rules have not been taken into account, the case Terebratulina caputserpentis could happen. None of the WBD editors have read Zbyszewski (1957). They know that every brachiopod specialist must be aware of Terebratulina caputserpentis (Linnæus, 1767) = T. retusa (Linnæus, 1758) as type species of Terebratulina Orbigny, 1847; this genus is the one having the largest number of extant species (25) and also of Tertiary genera (Thomson, 1927; Emig et al., 2013). The change could only have been made by the WoRMS staff, who ensure technical maintenance of the database WBD, unbeknownst to the editors; that action constitutes a professional misconduct. It seems clear that the effects have not been assessed, i.e., the propagation of this false information through various web sites and databases, and even Wikipedia, thus questioning of the scientific credibility of the publishers. The editors immediately corrected the page in WBD. It is now up to those responsible of WoRMS to make arrangements to avoid such future possibilities. They should also inform all who have been mislead by this manipulation.

This case reveals the fragility of scientific databases, some of which contain hundreds or even thousands of species. It is impossible to regularly check all the taxonomic entries, which is a flaw that can lead to errors by technical staff out of scientific control. Previous similar cases have already been reported, however no action has been taken to prevent future such mistakes. These changes jeopardize the scientific credibility of all databases and for that represent an Achilles heel. The copy-paste from one database to others should not excuse the obligation for other editors to check the validity of the transferred data.

To illustrate this remark, another recent case in WBD can be cited: the inarticulated brachiopod Lingula anatina, a tropical to warm temperate species, unknown in European waters, has suddenly and incorrectly been reported in British waters by MSBIAS (Marine Species of the British Isles and Adjacent Seas). By crediting the Lingula anatina WBD page by the MSBD web site, this citation implies the scientific expertise of WBD-WoRMS. Another example in GBIF (Global Biodiversity Information Facility) is the report of Terebratulina caputserpentis (Zbyszewski, 1957) in Canadian Atlantic waters based on a handwritten list under Terebratulina caputserpentis. Actually, the valid species in this region is T. septentrionalis (Couthouy, 1838). Similarly, in several genetic and molecular databases, synonyms appear as valid species, and consequently even in scientific publications.

Such errors are usually based on reference to publications, reports, and other documents, or simply photographs, still without scientific expertise concerning the species, i.e., verification of the identity and the validity of the name. It is also forgotten that the identification of specimens is carried out on a set of taxonomic characters which usually require dissection, as for brachiopods, or more elaborate techniques such as use of electron microscopy or histology as for Phoronida (see Emig, 1979). Following the fashionable tendency on biodiversity, the mapping of taxa is based on these databases. But here also errors in identification or in nomenclature lead to incorrect species distributions, which cannot be used for scientific interpretation, in particular when dealing with biodiversity. Furthermore, one can also add that about 10-30% of fossil and current species of brachiopods described by specialists are in fact synonymous.

In summary, because the databases are no longer completely reliable, therefore they cannot serve as references for the scientific community unless the taxonomy is vetted by specialists. The Peter principle (Peter & Hull, 1969) applies to the management of the databases related to biodiversity.
