ON MOLLUSCA OF THE WEST COAST OF NORTH AMERICA. 177 



The following is a list of the additional species described, so far as they may 

 be supposed to belong to the West N. American province ; the references to 

 the species already described by Brod. and Soiv. being appended to the 

 former list. The diagnoses are in English ; the plates beautiful and accu- 

 rate, sometimes, however, too highly coloured.

* From this page to the end, the work is edited by Mr. G. B. Sowerby, principally from 

 Mr. Gray's MS. 



t As Mr. Gray quoted the Zool. Atl. in the earlier part of this work, it is remarkable that 

 he did not adopt Eschscholtz's genus Acmcsa, instead of Lottia, which, with others in the 

 same work, appear only one step removed from the nonsense names of Adanson.
