FROM THE COAST OF BRITISH COLUMBIA. 119 
HINNITES GIGANTEUS, Gray. Entrance to Malaspina Inlet, associated with the two pre- 
ceding species, one rather small and dead specimen. Low water at Fort Rupert, 
on the north-east coast of Vancouver Island, one adult living shell, and a similar 
one from the entrance to Quatsino Sound, also at low water. 
PECTEN ALASKENSIS, Dall. Quatsino Sound at station No. 20, one small but living 
specimen. This species, which has hitherto been recorded as occurring only at 
North Harbor, Unga Island,” and “ Port Etches, Chugach Gulf,” is new to the 
Vancouver region. 
PECTEN HASTATUS, Sowerby. (=P. hericeus,Gld.) Strait of Georgia at station No. 6, one 
living, adult shell, with the exterior of both valves nearly covered by an encrusting 
sponge. Goletas Channel, one small but living shell. Quatsino Sound at station 
No. 19, five adult, living and brightly coloured specimens of the typical form of 
the species, in which the principal ribs are few, distant, and ornamented with erect 
vaulted scales. 
PECTEN HASTATUS, var. HINDSI1, Carpenter. Strait of Georgia at station No. 5, two rather 
small, living shells and a few fragments. Discovery Passage at station No. 7, two 
small, living shells and three single valves. Johnstone Strait at station No. 10, 
four medium sized, living specimens (one passing distinctly into the var. rubidus) 
and a few very small ones. Queen Charlotte Sound at station No. 14, one living 
specimen ; at station No. 17, three small living shells; and at station No. 18, one 
small, living shell. Quatsino Sound at stations No. 19 and 20, a few living speci- 
mens of various sizes. 
LIMATULA SUBAURICULATA, Montagu. Johnstone Strait at station No. 10, and Queen 
Charlotte Sound at station No. 14, a single living specimen from each of these 
localities. Not included in the Vancouver fauna in Dr. Carpenter’s “ Guide to the 
Diagnosis of the Vancouver and Californian Shells,” on pages 122-150 of his last 
report on “The Mollusks of Western North America,” published in 1872 by the 
Smithsonian Institution. 
YOLDIA LANCEOLATA, J. Sowerby. Quatsino Sound at station No. 20, a few living specimens. 
VOLDIA (PORTLANDIA) THRACIÆFORMIS, Storer. From the same station as the last, two 
small but living specimens. This species also is new to the Vancouver district. 
LEDA Fossa ? Baird. Discovery Passage at station No. 7, one single and worn valve. 
LEDA MINUTA, O. Fabricius. Quatsino Sound at station No. 19, two living specimens. 
LEDA ACUTA, Conrad. (—L. cuneata, Sowerby.) Same locality and station as the preceding ; 
ten perfect specimens (most of which were living) and three single valves. 
A single valve of a Leda from Houston Stewart Channel, Queen Charlotte 
Islands, which was referred by the writer to the Leda celaia of Hinds (on p. 200 B 
of the Report of Progress of the Geological Survey for 1878-79) is almost certainly 
referable to ZL. acuta, Conrad, of which, according to Dall, L. cuneata, Sowerby, is a 
synonym. On the other hand, in the sixth volume of the “ American Journal of 
Conchology,” (p. 55) Dr. J. G. Cooper sug ggests that Leda cuneata may be only a 
variety of L. cælata.
