species almost entirely upon the authority of the late Dr. P. P. Carpent 
Dr. W. H. Dall, however, regards both the Cardium var. centifilosum, 
Carpenter, and C. Richardsoni as synonyms of C. modestvm.

Gasteropoda. 
Emarginula crassa, J. Sowerby. 
An adult shell of this species, with the animal, was found in a jar 
containing large specimens of Solaster Stimpsoni, S. Dawsoni, Cribrella 
Iceviuscula and other starfishes characteristic of the British Columbia 
marine fauna, preserved in alcohol, the contents of which, except the 
alcohol, were stated by Dr. Dawson to have been dredged by him at the 
Queen Charlotte Islands in 1878. 
Pachypoma inequale, Martyn. 
This shell, which is very common in the Vancouver region, was 
identified by Dr. P. P. Carpenter with P. gwberosum, Chemnitz (sp.), 
but Dr. Dall says that " Martyn's name is four years older," and there- 
fore should be retained for it.
