FROM THE COAST OF BRITISH COLUMBIA. 131 



/TuRBONiLLA VANCOUVERENSis. ( Cliemnitzia 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. 



ODOSTOMIA SITKENSIS, Dall. Strait of Georgia at station No. 2, one living and full-grown 

 specimen. 



.EULIMA POLITA, L. Living and frequent in the Strait of Georgia at stations Nos. 5 and 

 'I, in Discovery Passage at stations No. 7 and 8, in Johustoue Strait at station No. 

 10, in Quern Charlotte Sound at stations Nos. 14, 15 and 1*7, 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 E. micans of Car- 

 penter, in " Canadian Naturalist," Vol. VIII, N. S. ; but Dr. Carpenter himself 

 regarded E. micans as " perhaps a smaller variety of the European E. polita." 



,- EULIMA INCURVA, Renieri (=.. 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. 



y 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, Fabridus. Queen Charlotte Sound at stations Nos. 12 (three living 

 specimens), 1*7 (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 undatocostata. 



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, 13, 

 15, 16, 17 and 18. Taken living also, in some numbers, at low water in Johnstone 

 Strait and the Goletas Channel. 



/ VELUTINA I^EVIQATA, 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
