Use of eponyms in the Société malacologique de France

The principles of the Bourguignat’s « Nouvelle Ecole » are explained in the introduction of the first volume of the Bulletins (with s) de la Société malacologique de France (SMF), created in reaction of the Journal de Conchyliologie co-edited by Hippolyte Crosse & Paul-Henri Fischer. Nearly 700 species were described in the 7 volumes of Bulletins, during 1884 to 1890 (Bourguignat died in 1892). Of these 700 species, 65 % were described by the founders of the Bulletins (Ancey, Bourguignat, Caziot, Fagot, Letourneux, Hagenmüller, Locard, Mabille, Poirier, Rochebrune, Saint-Simon, and Servain) and 22 % by associated members (e.g., Bofill, Euthyme, Florence and Jousseaume). But effectively, many descriptions were published under the responsability of Bourguignat, Locard or Fagot. For example: with some associates (e.g., Pechaud) or foreign correspondants took La Rédaction the liberty to adapt the text with the criteria of the Nouvelle Ecole. The writing style of Bourguignat or Servain can be seen in many papers and we know that Bourguignat used pseudonyms* or added informations without notice the author (read for example : « Mélanges et Nouvelles » published in Magasin de Zoologie pure et appliquée (v. 18 – 1866) in which we learn that Bourguignat modified the original text of Paladilhe to insert personal attacks against Gassies). Many diagnoses or descriptive texts are manuscripts of Bourguignat or can be attributed to Bourguignat. The Excursions malacologiques are an opus of Bourguignat for 90 % (some parts in quotation marks, other parts without quotation marks but the text still can be attributed to Bourguignat). Returning to the Bulletins, it is obvious in particular with the foreign contributors that the role of the Rédaction is very important.

Compare for example, the text of Schröder (SMF, vol. 2 : 215): « Cette espèce, du groupe de l’intermedia, à laquelle M. Bourguignat a bien voulu attribuer mon prénom, se trouve… » with Silva e Castro (SMF, vol. 2 : 278): « Cette espèce, de la série des Ventricosiana, à laquelle M. Bourguignat a bien voulu attribuer mon prénom, a été recueillie … ». These two articles are presented exactly in the same way (e.g. compare p. 216 and 278)! Very often the papers included descriptions of Bourguignat & cie (in sched., in litteris, Bourg. mss, etc.) and very often one of the new species is an eponym.

Example: Jousseaume (SMF, vol. 7: 81): Ovatella jousseaumei Bourg. In litt (p. 93) and Coelestele Bourguignati (p. 95); or Bourguignat (SMF, vol. 2 : 141): Tiphobia jouberti Bourg. (p. 146) and Tiphobia bourguignati Joubert. In litt (p. 148). We may regards these as little gifts between friends…

We have even the case of a paper (Servain, SMF, vol. 7: 281) in which a new genus and a new species are described by Bourguignat: Chambardia letourneuxi (dedicaced to Chambard and Letourneux) included a Chambardia bourguignati described by Letourneux; hence Chambardia bourguignati Letourneux in Bourguignat in Servain would be the full citation! These multiple eponyms are frequent inside the same publication. One of most famous is the « Monographies des genres Pechaudia and Hagenmulleria découverts en Algérie » by Bourguignat in 1881 in which are described all combinations : Pechaudia letourneuxiana, Hagenmulleria pechaudi, Hagenmulleria letourneuxi, Lhotelleria pechaudi, Lhotelleria letourneuxi. In SMF, vol. 4, Hagenmüller has dedicated four « letourneuxi », one in each new genus (Chancelia, Delevieleusia, Faudelia, Tetraspis) of his publication with this comment:


In the SMF volumes, we can find more than 60 eponyms for founders of the SMF, of which one third for Bourguignat! Nearly 160 different people received at least one eponym; in total nearly 250 names are eponyms, this is 35 % of the new names introduced in these volumes.


In addition, we see that a part of these eponyms had been choosen from the first name and/or to thank a malacologist’s wife:
Anodonta reneana Pechaud (SMF, vol. 1) to Jules-René Bourguignat
Anodonta richardi Bourguignat (SMF, col. 2) to Richard Schröder
Anodonta josei Bourguignat (SMF, vol. 2) to José da Silva e Castro
Digyreideum renei Letourneux (SMF, vol. 4) to Jules-René Bourguignat
Limnaea mongazonae Servain (SMF, vol. 4) to Mme Alix Servain (borned Loir-Mongazon)
Physa alixiana Servain (SMF, vol. 4) id.
Unio mongazonae Servain (SMF, vol. 4) id.
Valvata mongazoniana Servain (SMF, vol. 4) id.
Pedipes leoniae Ancey (SMF, vol. 4) to Mme Léonie Deschamps (wife of Mr Deschamps)
Pedipes deschampsi Ancey (SMF, vol. 4) id
Bulimus arnouldi Sayn (SMF, vol. 5) to Arnould Locard
Helix biagioi Bourguignat (SMF, vol. 5) to Biagio Kléciak

Visualised as a network, the (co-)authors and the persons they awarded eponyms is shown below:



* e.g. Servain (1891): “Les travaux de notre Collègue sont nombreux : ils atteignent le chiffre de cent quinze. Eh bien ! ces ouvrages forment à peine la moitié ce qu’il a fait paraître ou en volumes séparés, ou des Revues, voire même dans des journaux, soit sous le nom de ses amis, soit sous des pseudonymes, soit sous des astérisques”.


Hippolyte Mittre: an early malacologist

It is not known where and when Hippolyte Mittre was born. Mittre studied medicine, possibly in Montpellier where he defended in 1837 his thesis entitled ‘Essai sur la nostalgie’ (O’Sullivan 2012: 641). Later he became surgeon at the naval port in Toulon. From his papers it is clear that he travelled to the Caribbean and received material via others from localities overseas. He published only a few papers, but it is remarkable that he paid ample attention to the morphology of the animals. In that sense, he was one of the few malacologists among his contemporary conchologists and was ahead of his time. He died 1 January 1851 in French Guiana (Petit de la Saussaye, 1851).



His publication list is only modest and lists six papers:
1841 [March] Descriptions de quelques coquilles nouvelles. Revue zoologique par la Société Cuvierrienne (1841): 65–70.
1842 [September] Description de quatre coquilles nouvelles. Annales des sciences naturelles, Zoologie (2) 18: 188–191.
1844 Mémoire sur le genre Anatine. Magasin de Zoologie, d’Anatomie comparée et de Palentologie (2) 6: 1–18 [Mollusques Pl. 102-104].
1847 [February] Notice sur l’organisation des Galeolemma. Annales des sciences naturelles, Zoologie (3) 7: 169–181.
1850a [15 April] Notice sur le genre Cypricarde. Journal de Conchyliologie 1 (2): 125–130.
1850b [15 August] Notice sur les genres Diplodonta et Scacchia. Journal de Conchyliologie 1 (3): 238–246.

Malacology and its social context (3)

Of most malacologists no archival data is preserved, and especially complete correspondence archives are rare. So if one tries to reconstruct the contact network one may use a few sources; e.g., in publications often several names turn up as suppliers of material (either as field or as cabinet collectors), in the collection (if preserved) labels may point to collectors or colleagues with whom material was exchanged, and (in some rare cases) correspondence may reveal some of the contacts.

In the case of Henri Drouët (1829–1900) all three sources could be used and revealed a quite extensive contact network of more than 100 persons. The following figure gives a picture of his network, distinguished according to the following roles: malacological authors (MA), authors from other disciplines (AO), field collectors (FC), and other contacts (OT). The persons in the first three categories all received one or more eponyms.



This picture also makes clear that  eponyms may be used as a proxy for contacts of an author.

Sikora: an Austrian dealer based in Reunion

Franz Sikora (1863–1902) was an Austrian collector and dealer.

He was born on 12 January 1863 in Stockerau, near Vienna, Austria. As a youngster, he left Austria for Africa, where he married with Marie Amalie Teia in Zanzibar and moved to Reunion with his family. He explored Reunion island (Cilaos, Saint-Leu etc.) and collected many zoological specimens which he sold to different buyers in Europe.

During seven years from end of 1880s, he was entrusted with a scientifical mission by the Austrian gouverment; he lived in Antananarivo or Tananarive (Madagascar) and he frequented the Protestant mission based in Andrangoloaka (Battistini & Richard-V., 1972) from where he brought back important collects (insects, plants, shells…). After Beolens et al. (2011): “he discovered some remains of giant lemurs and early human settlers at Andrahomana Cave, Madagascar (1899)”. He was in contact with Alfred Grandidier (1836-1921), a great naturalist who explored Madagascar as nobody else (His Histoire physique, naturelle et politique de Madagascar count ab. 30 vol.). We know that Sikora took many photographs of plants, and several photographs were given to Grandidier (e.g. the plant Pachypodium ramosum wlas described on a specimen of Grandidier and on a photograph that Sikora who had given him) and conserved in his herbarium (MNHN). Some photographs taken by Sikora are present in the photographic library Grandidier in ORSTOM (Feller & Sandron, 2010).

After his stay in Tananarive, he moved to Fort-Dauphin before returning to Reunion until his death.

He worked with some museums (e.g., Wien, MNHN, BMNH, Turin). Various animals, vertebrates and invertebrates, were named after him; included two molluscs: Ampelita sikorae Ancey, 1890 and Cyclostoma sikorae Fulton, 1901.


Example of publicity in the Feuille des Jeunes Naturalistes

He died in Reunion Island in May 1902, but the day and the locality seemed unknown until now. The Ultramarine Archives (ANOM) on line allowed to find these information, in searching for each municipality one after the other! It appeares he died on 23 May 1902 in La Plaine-des-Palmistes (Reunion Isl.). The act is written in French, the name is francized: François Sikora. We learn also he was in resort since two years in this municipality and was known there as naturalist.

Malacology and its social context (2)

Social network analysis (SNA) is currently mainly a theme within sociology, but the study of networks has received some attention from other disciplines as well (e.g, physics). Since it is possible to build social networks from empirical data and use software to visualise the results in graphics, it becomes interesting to see if historical data relating to malacologists may be usefully applied with these methods.

An important distinction in SNA is between ‘egocentric social networks’ (hereafter ‘egonets’) and ‘whole social networks’ (hereafter ‘networks’). In the historical context we are interested in, an egonet always takes always the perspective from one person and tries to study his/her relationships. In the case of malacologists thus the relationship between malacologist A (‘ego’) and malacologist B, C, D, etc. (the ‘alter(i)’).


But this figure makes also clear that there may relationships between the alter(i). So one has to define the network boundary, or alternatively one studies a large group (of which the egonet of malacologist A is only a part); this is a ‘whole social network’ (also with a defined boundary, e.g. the European malacologists, which does not mean that alter(i) from outside Europe may not be included; it all depends on the research question).


One example of a question that one could ask is: What flows through the network from one individual to another? In a malacological network e.g., one could make a distinction in the development of contacts between two persons of the following, nested categories: (a) the exchange of questions, ideas or informal knowledge (through correspondence or meetings); (b) the exchange of material (i.c. dry shells or preserved molluscs), and (c) the exchange of formal knowledge (i.c. in publications or through reprints).

Lamare-Picquot: collection

Lamare-Picquot (1785-1873) is a famous french explorator: Mauritius, Indes, Turkey, and also North America from where he tried to introduce in Europe some species, e.g., Psoralea esculenta (the “Picquotiane”) instead potatoes… Lamare-Picquot was a great naturalist, also ethnologist, correspondent of Academy of Sciences and of the Muséum national d’histoire naturelle, in Paris. He obtained some fame because of his theory that reptiles could suckle the milk from udder, a theory classified under the category “prejudices”, by Duméril and Bibron. Lamare-Picquot has given many collections to MNHN, while others were sold (e.g., to BMNH) to finance his voyages.

According to Chaigneau (1982), who consulted the National Archives (AJ 15-548), we learn that his zoological collections were shared at the end of his life between MNHN and different universities:


In Lyon University, we found in the general collection a shell, which was apparently obtained by this sharing in 1865.

Miot: bio, collection

Henri (or Henry) Calixte Miot (1841-1938) was linked by his family ties to the Diderot family, and hence to the famous encyclopedist Diderot. He was born on 3 June 1841 in Langres (France, Haute-Marne) in a family of lawyers. His major commitment in his career was about justice, and also the protection of animals. In particular he wrote a little book on the legal implementation of animal protection (domestic animals mistreated) (Miot, 1870b). Member of the Société protectrice des Animaux, he was convinced (just as Duméril) that the birds, the reptiles and the insects were useful to regulate the populations of the insect pests, and that we need to protect them (Miot, 1870a).

Settled in the surroundings of Dijon, he was in the magistracy as substitute for the Imperial Prosecutor in Semur-en-Auxois (France, Côte-d’Or), and later as investigating judge in Beaune. He was also a great collector. We know in particular that he was interested in philately [1] and in bibliophily. In natural sciences, he was interested in entomology, geology and malacology. His collection is housed in the geological collections of the University of Burgundy (UBG).


It consists of seven drawers exclusively dedicated to Unionid shells, with some Cyclas and Corbicula species (233 lots). The material originates from North America (United States and Canada), Africa and Middle-East (Gabon, Algeria, Egypt, Iraq) and Europa (Spain, France and Italy). The majority of the specimens is from France, and their provenance shows they originate from the Drouët collection. Henri Drouët (1829-1900) was an administrator and a famous conchologist specialized in the Unionidae family, living in Troyes before moving to Dijon. The two persons were in close connection but probably only at the end of Drouët’s life. He mentioned him for the first time in 1898 in Unionidés du Bassin de la Seine, and probably he did not have time to give him an eponym. Besides Drouët, some other collectors appears in the provenance data of his collection, such as Léon Provancher (1820-1892) and Mr. Pétot.
