Cancellaria (Trigonostoma) circumecincta, Dall, Proc. Cal. Acad. Sci., vol. v., p. 58, 
pl. ii., fig. 2 (1873). 
Here again we have three species very nearly allied, but probably 
distinct. à 
C. modesta was described from Swan’s collection, and has not been 
since noticed in this province. 
C. Unalashkensis and circumcincta were described and figured by 
Dall,! the first from Unalashka, where, he says, modesta also was found, 
and the latter from Popoff Strait, Shumagin Islands. 
C. Unalashkensis has since been found at Victoria and Clayoquot 
Sound by Dr, Newcombe, and circumcincta has been dredged by Dawson 
at Forward Bay, Freshwater Bay and Cullen Harbour, and by myself in 
Departure Bay, near Nanaimo.

Cancellaria Couthouyi, Jay, Catalogue, ed. 3, pt. 77 (1839). 
= C. buccinoides, Couthouy, 1838 (preoccupied ), 
= viridula, Auct., non O. Fab. 
This Atlantic species was added to our list by Whiteaves, who 
records six specimens as having been taken at various points in Queen 
Charlotte Sound by Dr. Dawson. Dr. Newcombe has since taken a 
specimen near Victoria. Dr. Dall has pointed out (Proc. U. S. Nat. 
Mus., ix., 1886, p. 298) that this species is not the Tritonium viridulum of 
O. Fabricius, although it has long gone under that name.
