Tiyon, in his catalogue of Cardiidm, 1871, ignoren Carpenter's name 

 ;iiul re-nanies the species Adainsi, on the ground that modestum is pre- 

 occupied by Philippi. 



Mr. Whiteaves, in the "Ottawa Naturalist" for December, 1893, 

 p. 131, acknowledges his C. Richardsoni to be a synomyn of C. modestum, 

 Ad. and Eve., but says that he described it '' as a new species almost 

 •entirely on the authority of Dr. Carpenter," who would thus seem to 

 have failed to recognize his own C. centifiiosum. There is little doubt, 

 however, that all the above mentioned names refer to one and the same 

 species. 



S. centifiiosum is not a common shell with us. Mr. Eichardson 

 dredged a single living specimen (the type of C. Richardsoni) in 30-50 

 fathoms, between Eace Island lighthouse and Victoria Harbour. I 

 have dredged a few living and several dead shells in the same locality 

 iind in De})arture Bay. Other recent collectors do not seem to have 

 met with it.

This tine species is not very common. Eichardson dredged it alive 

 3A Victoria ; Dawson took it in some numbers at the Queen Charlotte 

 Islands and subsequently in Duncan and Freshwater Bays. I have my- 

 self dredged it alive in Departure Bay. and Dr. Newcombe has found it 

 both living and dead at Victoria. It is a dull, heavy shell with strong 

 concentric ribs and distinctly crennlated edges to the valves

Plentiful in sand between tide marks near Victoria, and also com- 

 mon, according to Dr. Newcombe, at Comox and Clayoquot. Professor 

 Macoun also collected it at Sooke. Dr. Dawson did not tind it at the 

 Queen Charlotte Islands or elsewhere, but as he did very little shore col- 

 lecting he might easily pass over so small a shell.
