134 WHITEAVES ON MAEINB INVERTEBRATA, ETC., 



,OciNEBRA LURIDA, Middendorf. Low tide in Johnstons 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 

 .Tohnstone 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 

 Quatsiuo 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 G-eorgia ; 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 TENTJISCTJLPTTTS, Carpenter. (=T. subserratus, Sowerby.) Not uncommon, alive, 

 at low tide, on the north side of the Strait of G-eorgia, in Seymour Narrows, and in 

 the Goletas Channel. A few living specimens, also, were dredged in Discovery 

 Passage at station No. I 7, in Johustoue Strait at station No. 10, in Queen Charlotte 

 Sound at stations Nos. 12, 16, 17 and 18, and in Quatsiuo 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),
