This cockle is never found living above low water mark, but has 

 been di'edged, though not xerj ahundantlj';, wherever dredging has lieen 

 carried on. 



At Victoria, Avhere we have had the o[)portunity to examine a 

 number of specimens ; there appear to be two varieties differing in shape 

 and number of ribs, (xould in his desci'iption of Cardium blandum. 

 which clearly refers to our shell, speaks of this variation in form. The 

 ribs are often nearly 50 in number, and the interior of the shell is 

 frequently more or less tinted with rose colour. 



There is a third species of Cardium (the name of which 1 have not 

 been able to ascertain) abundant in the Leda clay at Victoria.

Chemnitz was not binomial in volume vi., and his name is not there- 

 fore entitled in strictness to priorit3^ 1^ would serve no good purpose 

 however to change a name that has come into univei-sal use. 



1 have dredged dead specimens of this shell at Victoria and 

 Departure Bay, and Dr. Newcombe has obtained it in these places and 

 alive in Deep Bay, near Comox. He also reports it as fossil in the 

 boulder cla}- in various localities.

According to Mr. Whiteaves a single living .specimen of this species 

 was dredged by Mr. Richardson, near Victoria, in 1875. but no other 

 specimens have been obtained here so tar as I know.
