FROM THE COAST OF BRITISH COLUMBIA. 131 
TURBONILLA VANCOUVERENSIS. ( Chemnitzia Vancouverensis, Baird.) Discovery Passage 
at station No. 7, one living shell; Johnstone Strait at station No. 10, one living 
shell; Queen Charlotte Sound at station No. 13, eight living examples of a white- 
shelled variety of this species. 
OposToMIA SITKENSIS, Dall. Strait of Georgia at station No. 2, one living and full-grown 
specimen. 
Eurima pouira, Z. Living and frequent in the Strait of Georgia at stations Nos. 5 and 
6, in Discovery Passage at stations No. 7 and 8, in Johnstone Strait at station No. 
10, in Queen Charlotte Sound at stations Nos. 14, 15 and 17, and in Quatsino 
Sound at station No. 20. 
About fifty living specimens of this shell were dredged by Dr. Dawson, and 
the only observable difference between them and authentic English examples of 
E. polita is one of size, the former attaining frequently to a length of thirteen milli- 
metres, while the latter are sometimes as much as sixteen mm. long. Smaller 
specimens of the same shell were dredged by Mr. Richardson in the Strait of 
Georgia in 1875, and these were referred by the writer to the Æ. micans of Car- 
penter, in “Canadian Naturalist,’ Vol. VIII, N. 8.; but Dr. Carpenter himself 
regarded E. micans as “perhaps a smaller variety of the European Æ. polita.” 
EULIMA INCURVA, Renieri (—E. distorta, auct.) With the above, but not nearly so common, 
at stations Nos. 6, 10 and 14. Two living specimens were also taken at low tide in 
Discovery Passage, between Seymour Narrows and Elk Harbour, and one at low 
tide in the Goletas Channel. 
ScaLARIA INDIANORUM, Carpenter. One fine, living adult specimen of this species, measur- 
ing nearly an inch and a half in length, was dredged in Discovery Passage at 
station No. 7. 
CANCELLARIA CIRCUMCINCTA, Dall. Johnstone Strait at station No, 10, one living and 
adult specimen; Queen Charlotte Sound at station No. 12, a series of about twenty 
living specimens, and at station No. 13, one full-grown living shell. 
ADMETE VIRIDULA, Fabricius. Queen Charlotte Sound at stations Nos. 12 (three living 
specimens), 17 (two living specimens), and 18 (one living specimen). Most of 
these belong to the short-spired variety of the species, to which Verkruzen has 
given the name wndatocostata. 
TRICHOTROPIS CANCELLATA, Hinds. Dredged more or less abundantly, alive, in the Strait 
of Georgia at station No. 5, in Discovery Passage at station No.7, in Johnstone 
Strait at station No. 10, and in Queen Charlotte Sound at stations Nos. 12, 18, 
15, 16, 17 and 18. Taken living also, in some numbers, at low water in Johnstone 
Strait and the Goletas Channel. 
VELUTINA LÆVIGATA, L. Discovery Passage at station No. 8, one living specimen. 
NATICA CLAUSA, Broderip and Sowerby. Taken sparingly, but alive and in some cases of 
considerable size, at low water, on the north shore of the Strait of Georgia; in
