FfiQM THE COAST OF BRITISH COLUMBIA. 129 



In one of the specimens collected by Dr. Dawson the columella has a greenish 

 iridescence not unlike that of some varieties of labradorite. 



MARGARITA ITPILLA, Gould. Collected sparingly, alive, at low water mark in Beaver 

 Harbour (on the north-east coast of Vancouver Island), in the Goletas Channel, on 

 the east side of Queen Charlotte Sound, and at the entrance to Quatsino Sound. 

 Dredged also, in small numbers but living, in the Strait of Georgia at stations 

 Nos. 2, 5 and 6, in Discovery Bay at station No. 7, in Johnstone Strait at station 

 No. 10, in Queen Charlotte Sound at stations Nos. 12, 14, 16, 17 and 18, and in 

 Quatsino Sound, at station No. 20. 



MARGARITA LIRULATA, Carpenter Discovery Passage at station No. 17, one very small 

 living specimen ; Queen Charlotte Sound, at station No. 12, about twenty adult 

 living specimens ; and Quatsino Sound at station No. 20, one living and full- 

 grown shell. 



In the seventh volume of the " American Journal of Conchology," (pp. 128, 

 129) Mr. Dall expresses the opinion that Gibbula oplabilis, Cpr., G. parcipicta, Cpr., 

 G. funiadata, Cpr., G. sucrincla, Cpr., and perhaps G. lacunata, Cpr., as well as 

 Margarita tenuisculpla, Cpr., are all forms of the present " protean species." 



MARGARITA HELICINA, Fabricius. Low tide in Johnstone Strait, three immature, living 

 specimens. Dredged also in Queen Charlotte Sound at stations Nos. 12 and 16, 

 one living, adult shell at each. 



CREPIDTJLA DORSATA (Broderip), var. LINOTJLATA, Gould. (=C. bilobata, Reeve.) Low tide 

 at the entrance to Malaspina Inlet, in the Strait of Georgia, and in Quatsino 

 Sound ; three or four living specimens at each locality. Dredged also very 

 sparingly, but alive, in the Strait of Georgia at station No. 2, and in Johnstone 

 Strait at station No. 10. 



CREPIDULA AUUNCA, Sowerby. Entrance to Quatsino Sound at low water, and on the west 

 coast of Vancouver Island, north of Quatsino Sound, also at low water, a single 

 specimen at each of these localities. 



CHEPIDUIA NAVICELLOIDES, Nuttall. Dredged in very small numbers, but alive, in Queen 

 Charlotte Sound at stations Nos. 12, 14 and 16. Mr. Tryon thinks that this shell is 

 only a local variety of C. Lessoni, Broderip. 



GALERUS FASTIGIATUS, Gould. Not uncommon and living, in Discovery Passage at station 

 No. 7, in Johnstone Strait at station No. 10, and in Queen Charlotte Sound at 

 stations Nos. 12, 14 and 16. The Galerus from the Queen Charlotte Islands, which 

 was named G. contortus, Gould, b / the writer, in the paper already referred to, is 

 almost certainly G. fastigiatus, but this latter name, Mr. Tryon says, is a synonym 

 of G. mamiUaris, Broderip. 



BIVONIA COMPACTA, Carpenter. Discovery Passage at station No. 7, a living specimen on 

 Trophon tenuisculptus, Carpenter ; and in Quatsino Sound at station No. 19, one 

 specimen, also living, attached to the under valve of a typical example of Pecten 

 hastatits.
