fine species and oceurs commonly in sand between tides on all our 
coasts. It is largely consumed by Indians and others in the proper 
season.

This cockle is never found living above low water mark, but has 
been dredged, though not very abundantly, wherever dredging has been 
carried on. 
At Victoria, where we have had the opportunity to examine a 
number of specimens ; there appear to be two varieties differing in shape 
and number of ribs. Gould in his description 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 I have not 
been able to ascertain) abundant in the Leda clay at Victoria, 
SERRIPES, Beck.

fig. 198. = edentulum, Montagu, 1808 (according to Carpenter). 
Chemnitz was not binomial in volume vi., and his name is not there- 
fore entitled in strictness to priority. It would serve no good purpose 
however to change a name that has come into universal use. 
I 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 clay in various localities.

Cardium Laperousti, Desh., Rev. Zool. Soc. Cuv., p. 360 (Dec., 1839); and Mag. de 
Zool. (Guerin’s), pl. xlviii. (1841). 
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 far as I know.
