FROM 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 PUPILLA, 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 optabilis, Cpr., G. parcipicta, Cpr., 
G. funiculata, Cpr., G. succincta, Cpr., and perhaps G. lacunata, Cpr., as well as 
Margarita tenuisculpta, 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. 
CREPIDULA DORSATA (Broderip), var. LINGULATA, 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 ADUNCA, 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. 
CREPIDULA 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. mamillaris, 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 
. hastatus, 
Sec. IV., 1886. 17.
