62. The following species* are extracted from Mr. Reeve's ' Conchologia 

 Iconica'; a work, the principal advantage of which is, that it figures the 

 specimens in the Cumingian collection. The species are often very minutely 

 subdivided : for this indeed the author may not always be answerable. Tt 

 is to be regretted that there is sometimes a want of precision in the statement 

 of localitiesf .
