 the name is attiiched to a very diifeient shell in Mus. Cum.] 



* Several species occur in the recent monographs without locality, which are well 

 linown to inhabit the W. Coast. This is partly due to the writer not thinking it neces-

 redistribution of species into the modern genera, the student is greatly aided in his search 

 for special forms ; but, for the sake of uniformity, the autograph labels of collectors or 

 tlescribers of species are generally rejected, the names being either in tlie handwriting of 

 the clerk or from the printed index in the monograph, and representing only the judg-
