184 WHITEAVES ON MARINE INVERTEBRATA, ETC. 
OCINEBRA LURIDA, Middendorf. Low tide in Johnstone Strait, one living, adult specimen ; 
Queen Charlotte Sound at station No. 13, an immature and dead shell. 
OCINEBRA INTERFOSSA, Carpenter. Living, at low tide, but by no means common, in 
Johnstone Strait and the Goletas Channel; on the east and north west coast of 
Vancouver Island, from Nahwitti Bar to Quatsino Sound, and at the entrance to 
Quatsino Sound. One adult, living specimen was dredged at station No. 20. 
CEROSTOMA FOLIATUM, Gmelin. Fine and frequent, living, at low tide, at Twin Island and 
the entrance to Malaspina Inlet, in the Strait of Georgia; in Johnstone and Brough- 
ton Straits ; in the Goletas Channel, and on the east side of Queen Charlotte Sound. 
Dredged also, living and adult, in Discovery Passage at station No. 7. 
TROPHON ORPHEUS, Gould. (=T. Stuarti, E. A. Smith.) Queen Charlotte Sound, at station 
No. 14, an immature, living shell, nearly an inch and a half long, with the varices 
prolonged behind into semitubular or deeply grooved, long, spiny frills, which 
curve lightly backward; at station No. 16, a living, adult shell, fully two inches 
long ; and at station No. 18, a beautifully preserved living specimen, an inch and 
a quarter in length, with the spinose frills prolonged to an unusual length behind. 
TROPHON CLATHRATUS, L. (=T. multicostatus, Eschscholtz.) Low water in Johnstone 
Strait, one adult, living specimen. A similar, but slightly larger one was dredged 
in Queen Charlotte Sound at station No. 12, and another at station No. 16. 
TROPHON TENUISCULPTUS, Carpenter. (=T. subserratus, Sowerby.) Not uncommon, alive, 
at low tide, on the north side of the Strait of Georgia, in Seymour Narrows, and in 
the Goletas Channel. A few living specimens, also, were dredged in Discovery 
Passage at station No. 7, in Johnstone Strait at station No. 10, in Queen Charlotte 
Sound at stations Nos. 12, 16, 17 and 18, and in Quatsino Sound at station No. 19. 
The largest specimens collected are a little more than an inch and a half in 
length. When examined with an ordinary simple lens, the whole surface of the 
shell of this species is seen to be almost covered by densely-crowded, minute, 
crenate and squamose raised lines of growth, which cross the spiral grooves and 
ridges and are superimposed upon the varices. The types of T. tenuisculptus are 
from the Pleistocene deposits at San Diego, but the shell is by no means uncommon 
in a living state on the coasts of Vancouver and the Queen Charlotte Islands. 
CEPHALOPODA. 
OMMASTREPHES SAGITTATUS, Lamarck. (Sp.) Three specimens of a squid, which corre- 
spond very well with Tryon’s description and figures of this species in the first 
volume of his “ Manual of Conchology,” were collected at low water in Victoria 
Harbour, Vancouver Island. 
The following is a supplementary list of fresh-water and land shells, fishes (marine), 
batrachians, ophidia, birds and mammals collected by Dr. Dawson and Mr. Dowling in the 
same district and season :—
