The Odostomias of British Columbia have not yet been satisfactorily 
worked up. Specimens are very common both between tides and among 
dredged material, and I have accumulated many hundred shells. I have 
never yet, however, had an opportunity of either critically examining 
these myself or submitting them to competent authority and therefore 
cannot write with confidence upon the subject. 
Of the seven species enumerated above, two, O. inflata and O. tenuis- 
culpta, are quoted on the strength of specimens collected by Swan in 
Puget Sound. 
A third, O. Sitkensis, is recorded by Whiteaves from the Queen 
Charlotte Islands and False Bay, Lasqueti Island; this species and 
O. straminea being apparently the only ones met with by Dr. Dawson. 
The other four species are in my own collection. 
O. satura, or the shell that I think to be this species, is the common 
large form in Departure Bay. 
O. nuciformis, which is the most easily recognized of our species
