BIBLIOGRAPHY. 



List of British Marine Shells, comprising those of 

 the Brachiopoda and Mollusca (Proper), after the ar- 

 rangement in Jeffreys' " British Conchology," with alterations 

 and additions to 1885, by A. Somerville, B.Sc, F.L.S., &c. 



A list of our Marine Shells at a reasonable price has long 

 been desired, and the one now before us, prepared by Mr. 

 Somerville, is excellently produced. In addition to specific 

 names, those of varieties are given, but in smaller type, these 

 however range in line with the specific names ; it would we think 

 be an improvement in future editions to indent the varietal 

 names, this would bring the specific names into greater 

 prominence and render reference more easy. The list is well 

 printed on good paper, and fills four pages of Foolscap. The 

 price is 3d. each, or 2/6 per dozen post free from the Publisher,

 The six fascicules of this beautiful work continue to 

 maintain the high standard of the previously published parts. 

 The photographic illustrations are excellent, and the text is 

 marked by carefulness, precision, and exactitude. The fifth part 

 is devoted to the family Cerithiadse, which is divided into five 

 genera, and a new sub-genus Biforina is established for T. 

 perversus L. The variation of each species is treated in a full 

 and elaborate manner. The Cerithium vulgatiim having twelve 

 named varieties of form, and three variations of colour. The 

 sixth and seventh fascicules are devoted to the Turritellidse and 

 the Littorinidae. Turritellidae is divided into five genera and 

 four sub-genera. The littorinidse are divided into three sections, 

 the first containing two genera — Littorina and Fossarus, the 

 former with the sub-genus Melaraphe. The second section has 

 only the genus Solarium. The third section contains eleven 

 genera and fourteen sub-genera, of which two Schwartzia 

 established for Rissoa monodonta Bivona, and Massotia of 

 which Rissoa lactea is the type, are new.
