FROM THE COAST OF BRITISH COLUMBIA. 121 
CRYPTODON SERICATUS, Carpenter. (Not “serricatus.”) Quatsino Sound at station No. 20, 
several small but living specimens. In a letter to the writer, Mr. Dall says “the 
specific name of this shell is misspelled in Dr. Carpenter's last report, but the 
mistake was corrected by him in MS.” 
LUCINA FILOSA, Stimpson. Quatsino Sound at station No. 19, one small but living shell; 
and at station No. 20, a large and perfectly fresh single valve. 
LUCINA TENUISCULPTA, Carpenter. Strait of Georgia at station No. 2, one living speci- 
men ; and Quatsino Sound at station No. 19, abundant, living. 
VENERICARDIA BOREALIS, Conrad. Living, but usually of small size, at the following 
localities :—Strait of Georgia at station No. 5, Johnstone Strait at station No. 10, 
Queen Charlotte Sound at stations Nos. 12, 14, 15, 17 and 18; and Quatsino Sound 
at station No. 19. A few dead valves of this shell were dredged at station No. 7, 
in Discovery Passage. 
ASTARTE UNDATA ? Gould, var. Strait of Georgia at station No. 5, two living and full- 
grown specimens ; Discovery Passage at station No. 7, two living specimens and 
several single valves, and Johnstone Strait at station No. 10, one living and 
unusually large specimen. 
The shells from station No. 5 can scarcely be separated from examples of a 
variety of A. undata dredged by the writer, in 1873, between Pictou Island and Cape 
Bear, P.E.I.; while those from stations No. 7 and 10 are more transversely elon- 
gated and more like A. elliptica in shape, but their ribs are fewer (some fourteen or 
fifteen in number) and more prominent, and shew little if any tendency to become 
obsolete near the ventral margin. A single dead and immature valve of an Astarte, 
dredged by Dr. G. M. Dawson off Metlakatla in 1878, and identified by the writer, 
with doubt, as possibly the A. semisulcata of Leach, in the Report of Progress of the 
Geological Survey of 1878-79 (p. 197 B) is certainly identical with the shells here 
provisionally referred to A. wndata. 
ASTARTE ESQUIMALTI, Baird. Strait of Georgia at station No. 5, two living specimens ; 
7, abundant, alive; Johnstone Strait at station 
No. 10, two living specimens ; and Queen Charlotte Sound at station No. 12, four 
Discovery Passage at station No. 
living shells, and at station No. 14, abundant and alive. In the specimens from 
these localities the irregularity of the concentric ribs is very slight and scarcely 
appreciable without the aid of a lens. 
CARDIUM BLANDUM, Gould. Strait of Georgia at station No. 5, Discovery Passage at 
station No. 7, Johnstone Strait at station No. 10, and Queen Charlotte Sound at 
stations Nos. 12, 13, 16 and 17. A few living specimens of all sizes from each of 
these localities. 
CarpiuM NUTTALII, Conrad. Common at or near low water mark throughout the district. 
SAXIDOMUS SQUALIDUS, Deshayes. Abundant at low tide round the whole coast. A few 
small specimens of the present species were dredged in Discovery Passage at station 
No. 7, and in Queen Charlotte Sound at stations Nos. 12 and 16. 
Sec. IV., 1886. 16.
