Nat. Hist., series 3, vol. xv., p. 398 (May, 1865). 
Dr. Carpenter, on p. 628 of his “Supplementary Report,” writes of 
the present species as “rare” among Swan’s Puget Sound and Vancou- 
ver Island shells, and on page 662 of the same report he places it in the 
Vancouver column. 
In his description of this species, however, in the Annals and Maga- 
zine of Natural History, he makes no mention of any locality for the 
shell north of Monterey. Perhaps the name should be struck off our 
lists, for the species does not seem to have been found in the province 
since Carpenter’s time.

C. gausapata is the northern form of carinata. The species is com- 
mon, and is found between tides or just below low-water mark all 
through the province. Dr. Newcombe, in his Catalogue, confuses this 
species with the next, which is, as far as I can see, undoubtedly distinct.

This is a much larger shell than the last named, and is further dis- 
tinguished by the possession of a thick and rough epidermis. It is 
generally obtained by dredging in ten to twenty fathoms, and has. been 
taken by myself and others abundantly at Victoria and Departure Bay ; 
also on the west coast of Vancouver Island, by Dr. Newcombe, and in 
many northern localities by Dr. Dawson. 
Tryon included this species in the synonymy of Astyris carinata, and 
Dr. Dall has also expressed the opinion that they belong together. I 
still think, however, that the species are distinct, as I have seen no 
approach to an intermediate specimen. 
Mr. E. A. Smith has redescribed this shell under the name Colum-
