Soon to be published: Morelet monograph

A monograph on Arthur Morelet

Those who are working with non-marine molluscs may have encountered the name of Morelet. He introduced more than 700 species names in – currently – 84 different families of land and freshwater molluscs. Who was Arthur Morelet and what has become of his huge collection?

Pierre Marie Arthur Morelet (1809-1892) was an amateur scientist who devoted himself to both shell collecting and botany. He organised several expeditions, of which those to Cuba and Central America (1846-1848) and the Azores (1857) are especially noteworthy. His contributions to malacology were thus significant and we have reconstructed his legacy with a survey of archival sources and his type material in the historical collections of several museums. 

The resulting monograph is made up of two parts. In the first part we present a bibliography, some remarks on the whereabouts of his collection, and more than 200 recovered letters (transcribed and translated) to contemporary malacologists, such as Crosse, Fischer, Baudon and Dautzenberg. His contact network has been reconstructed using data from his correspondence and his publications. This part offers an unique view into the world of malacology in the second half of the 19th century.

In the second part a bibliography of Morelet is presented, as well as all his newly introduced taxa, with detailed documentation and figures of the species. More than 80 per cent of his type material has been re-found and original figures, if they exist, have been reproduced for the remaining species. Of the taxa represented by actual shell material, more than 150 are now figured for the first time. The book has indices for both taxonomy and persons mentioned and is a must-have for anyone interested in the history of malacology and those dealing with non-marine molluscs.

The book, which has 544 pages and more than 1300 figures, is available after its launch on 23 June 2018. Thanks to financial support from Association Cernuelle (France), Royal Belgian Institute of Natural Sciences (Belgium), Natural History Museum (United Kingdom), and the Netherlands Malacological Society (Netherlands), the electronic version of the book is freely available at www.spirula.nl/andere-uitgaven/moreletEN. A printing on demand hard cover version of the book can be ordered at www.boekenbestellen.nl (search for title or ISBN) for

Ruminia decollata in Cordoba

Reyna & Gordillo just published a brief research note in which they report the finding of specimens of Ruminia decollata (Linnaeus, 1758) in Córdoba Province, Argentina.

According to these authors this snail is a potential host of roundworms that are common in dogs and cats, and thus may also affect susceptible humans. Moreover, this alien species may affect crops and horticultural products.

BHL is now better

The indispensable BHL is now even better: recently a ‘inside search’ button has been added, which allows the user to make a free search within the item under inspection. Read the full story here.

If you have used archive.org full text search you’ll know that the system shows the pages where your search term appears once you open the item.

The BHL interface doesn’t do that, and you have to repeat the search within the item, but when done it shows the contexts and gives page links.

Nevertheless, this will make searching for and within historical taxonomical literature much better and also save lots of time. Very nice!

Newly introduced snail

Agudo-Padrón is a frequent author of news about the southern Brazilian malacofauna. This time he published about a new introduction of a species from Asia, which he identified as Macrochlamys cf. indica (Benson, 1832).

This record was published in a new online journal from the University of El Salvador, named ‘Minerva’; a name which is already applied by at least 2 other journals and thus may be considered as a junior homonym 🙂

New Urocoptid from Hispaniola

Just released: a paper by Thomas Watters dealing with the urocoptid genus Gyraxis, and describing a new species. The abstract reads “The genus Gyraxis in Hispaniola is reviewed, currently only known from the area of the Bahía de Samaná in the Dominican Republic. It includes three taxa: Gyraxis samana (Clench, 1966), G. sericata (Pilsbry, 1903) and G. excalibur new species. The radular morphology and isolation from Cuban Gyraxis suggest they may yet require a new genus”.

Watters also, when dealing with the nomen inquirendum Cylindrella gouldiana Pfeiffer, 1853, indicated this taxon has never been figured and that Crosse subsequently mentioned the first precise locality for the species (“Région Dominicaine: rochers du Tablaso, près San Cristobal (A. Sallé)”). Watters expressed “it is not clear how he knew this”. This answer is simple: Crosse always indicated behind his localities the collector of the material, in this case Sallé. The material which Crosse saw may either have been returned to Sallé or have ended up in the Crosse collection. Both collections have been dispersed after their owner’s death, and the current depository of the material is unknown.
