dredged by Dr. Dawson in the Straits of Georgia, Forward Bay and 
Alert Bay and as occurring between tides in Discovery Passage and 
Goletas Channel. [have found specimens of the same shell at Victoria 
and Departure Bay both between tides and by dredging, and Dr. New- 
combe has specimens from Clayoquot Sound. 
tenieri I believe only published the name without any description, 
and as our shell does not appear to be the same as the #. distorta, 
Deshayes, of English conchologists, Iam not sure that it has at present 
any proper name.

Chemnitzia tridentata, Cpr., Rept. Brit. Assoc., 1863, p. 659 (August, 1864); and 
Journ. de Conch., vol. xii., p. 147 (April, 1865). 
This species was described from Puget Sound (Kennerley) and from 
Sta, Barbara, Monterey and San Pedro. It has not been found in our 
1 
waters by recent collectors.

Cheinnitzia Lordi, E. A. S., Ann. Mag. Nat. Hist., series 5, vol. vi., p. 288 (1880). 
À very few specimens of this species have been dredged by Dr. 
Newcombe and myself in Departure Bay. I have compared some of 
these with Mr, Smith’s types. This is the largest species of Turbonilla 
found in British Columbia,

Chemnitzia chocolata, Cpr., Rept. Brit. Assoc., 1863, p. 659 (August, 1864) ; and 
Proc. Cal. Acad. Nat. Sci., vol. iii. (1866). 
These two species are I think equally common. T. chocolata has been 
dredged at Victoria, Departure Bay and Clayoquot Sound. T. torquata, 
at the two first named places and also at Duncan Bay, Forward Bay 
and Cullen Harbour (Vancouver Island). Doubtless both species will 
be found in other localities when search is made. In California T. tor- 
quata is said to occur abundantly on the shells of Halotis (Orcutt).
