150 HELICID^. 



cific name oifraterna ; and in 1828, Wood gave a figure 

 of it as H. monodon. Yet, notwithstanding these proofs 

 that it was well known in England and the United States, 

 M. Dcshayes, in 1830, ten years after the first publica- 

 tion, produced another description under the name of He- 

 lix convexa, a name already preoccupied ; and has re- 

 tained it in the second edition of the " Animaux sans 

 Vertebres," in 1838. Lister's figure, Synops. Conch, t. 

 93, f. 94, represents this species.
