Bibliographie. 



In a notice of Morch's "Catalogus Conchyliorum qu£e 

 reliquit cl. N. Ch. N. Lassen," &c., M. Crosse makes the fol- 

 lowing remarks, to which we heartily agree : — 



"The author adopts, in great part, Dr. Troschel's classification, 

 exclusively based upon the lingual dentition of the Mollusks. 

 This system has the inconvenience of sometimes separating 

 animals, closely allied by all their characters, by their general 

 aspect and their manner of life, and differing only in this one 

 particular."
