ZOOLOGY.

Family TURBINIDiE . 
TROCHUS FILOSUS. 
TrochusJilosus, Wood, Ind. Test. Supp. pi. 5, f. 23, 1828.— Carpenter, Rep. Brit Assoc p. 320. 
Trochus ligatus, Gould in Proceed. Bost. Soc. Ill, p. 91, 1847.-—Exped. Shells, p. 185, fig. 207. 
Trochus modestus, Midden.? Beit II. pi. 85, p. X, f. 16, 17, 18, 1849. 
Hub .—Straits of De Fuca, Dr. Cooper ; Upper California, Dr. Trask. 
Not very common. T. modestus of Middendorff is considerably smaller, but otherwise much 
resembles this species. 
29. TROCHUS SCHANTARICUS. 
Trochus schantaricus, Midden. Beitrage II, 85, 12.— Idem, Beise, p. 204, pi. xviii, f. 1-7. 
Eah —Straits of Fuca, Dr. Cooper ; Sckantar islands in Sea of Ockotsk, Middendorff. 
This small species appears to be abundant in the above locality, and numerous specimens 
were collected. They all exhibit more or less perfection beneath, and are uniform in size, 
which is much less than T. Jilosus. In other particulars the two are nearly allied. 
Family HALIOTIDJE. 
HALIOTIS KAMTSCHATKIANA 
Ealiotis Kamtschatkiana, Jonas, Reeve, Con. Icon. Ill, f. 8.— Carpenter, Rep. p. 320. 
Hah .—Nootka Sound, Captain Russell. 
Several specimens of this beautiful species of Haliotis were brought from Nootka Sound by 
Captain C. J. W. Russell, of which four were presented to us by Dr. Trask. 
Young shells of H. rujescens bear considerable resemblance to this species, for which there 
is reason to think they have sometimes been mistaken. Among numerous specimens of Haliotis, 
sent to the Smithsonian Institution from different localities on the coast of California, I find 
none of this species from any more southern points than that given above, in latitude 49°. Mr. 
Carpenter also considers it doubtful as a California species. 
Haliotis corrugata, H. splendens, H. rufescens, and H. Cracherodii were sent from San 
Diego by Mr. Cassedy. H. californiensis must be rare, as none were obtained by any of our 
collectors or correspondents. 
Family FISSURELLIDiE, 
FISSURELLA NIGROPUNCTATA. 
Fissurella nigropundata, Sowerbe, Reeve, op. cit. 
Hab .—Santa Catalina, Dr. Trask ; Gallapagos, Cuming ; Panama, C. B. Adams. 
Two specimens of this shell, hitherto only found in the Panama province, were sent by Dr. 
Trask as coming from the island of Santa Catalina, near the coast of Upper California. 
FISSURELLA ASPERA. 
Fissurella aspcra, Eschsciioltz, Carp. Rep. 320, ( Glyphis.) 
Fissurella cratilia, Gould ? 
Fissurella denseclathrata, Reeve ? 
Hah. —Upper California, Lieut. W. P. Trowbridge ; Puget Sound, Dr. Gould.
