202 PKOCEEDINGS OF THE MALACOLOGICAL SOCIETY. 



unite in thanks for this excellent catalogue, wherein probably the 

 only weak spots will be found in connexion with those groups where 

 acknowledgment is accredited to his catalogue, such as the "family 

 Synceratidee ". There is no such group in valid nomination, being 

 simply another of Bartsch's blunders, the name Syncera Gray, 1821, 

 being a nomen nudum, and therefore unavailable in the connexion 

 cited. However, as to Mitra, Dall has continued, through 

 inadvertence, the quotation (p. 87) of Mitra Lamarck, 1799, ranking 

 Thala as a section only, a value quite unacceptable, the true Thala 

 probably not even belonging to the family Mitridae. On the same 

 page he includes the genus Mitromorpha A. Adams with a ? in front 

 of it. This cannot be understood in connexion with the facts without 

 explanation. The genus is quite valid, so we can only surmise that 

 the ■? refers to the position in the family, which is not a customary 

 mode of expression. 



The other item is the status of such a name as " Laphrostoma, 

 R. (1815) " for " Neritina, Lam." At the time that was written there 

 was no Latin name Neritina, the name only existing in the 

 vernacular " Neritine ". The anomaly will then exist, if these 

 prove acceptable, of the substitute name dating earlier than the one 

 for which it was provided. In the present case it would mean the 

 rejection of Neritina, Lamarck, even of 1816, in any connexion. 



Les Fonds de la Mer. 

 This rare, but important work is not known to all malacologists, 

 and, moreover, is not commonly accessible. In 1913 a copy was 

 secured by the British Museum (Natural History), and was examined 

 by me in connexion with Pyramidellid nomenclature. A little later 

 my friend, Mr. Alex Reynell, showed me some parts he had secured 

 and I borrowed them for comparison and made some notes. I have 

 just secured a perfect bound copy, which has enabled me to com- 

 plete my examination leisurely, and I here give my results. The 

 title page of Volume I states that it contains about 500 figures, 

 representing 250 species and 300 pages of text, " commencee et 

 dirigee par MM. L. de Folin and L. Perier," and published at 

 " Paris, Savy, Libraire-editeur, rue Hautefeaille 24, 1867-71 ". 

 The exact pagination is 316, and 33 plates are included. Vol. II 

 has the same wording, but "about 120 figures representing 

 60 species ", and the date is 1875. The exact pagination is 365, 

 and there are 11 plates with 11 explanatory pages. Vol. Ill has 

 again the same wording, with " about 115 figures representing 75 

 forms", and the date 1875--9. The exact pagination is 337, and 

 nine j^lateS; each with explanatory text. No information as to method 

 of publication can be gauged from these so that Reynell's parts are 

 very valuable. The covers read " Les Fonds de la Mer . . . par 

 MM. Berchon, De Folin, Perier . . . Edition avec planches, paraissant 

 par livraisons de 16 pages ". Reynell's lot consists of the fourth
