1 HE following List of English Trivial Names will 

 be found useful to purchasers of shells, as dealers 

 most frequently adopt them. It is, however, very 

 much to be wished that all names should be abo- 

 lished which are not strictly translations of the 

 Linnsean specific ones. The trivial terms are mostly 

 derived from some supposed resemblance to well- 

 known objects ; and are therefore liable to be 

 altered according to the fancy of collectors and 

 catalogue-makers, who, in fact, have contrived to 

 create as much uncertainty and confusion as could 

 be expected from such a source. There are doubt- 

 less many technical distinctions which are not in- 

 cluded in the subjoined enumeration, but the greater 

 part of those in common acceptation are so. None 

 of those are, of course, inserted which are merely 

 rendered from the Latin, as *' scaly Chiton" from 

 Chiton squamosus, except in a few instances where 

 the word is a substantive and not an adjective.
