ZOOLOGY. 375 
Family TURBINIDiE. 
TROCHUS FILOSUS. 
Trochuffilosiis, WnoD, Ind. Test. Snpp. pi 5, f. 23, 1R28.— Carpenter, Eep. Brit Assoc p. 320. 
Trnchits ligatus, Goi ld 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. 
Hah. — 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. 
Trocln/s sckantarims. Midden. Beitraffe II, 85, 12. — Idem, Reise, p. 204, pi. xviii, f. 1-7. 
Huh — Straits of Fuca, Dr. Cooper ; Schantar islands in Sea of Ocliotsk, 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.filosiis. In other particulars the two are nearly allied. 
Family HALIOTIDi^. 
HALIOTIS KAMTSCHATKIANA 
Ilaliotis KamtschatJciana, Jonas, Eeeve, Con. Icon. Ill, f. 8. — Carpenter, Rep. p. 320. 
Ilab. — 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. rvfescens 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 TIS S URE L L I D ^ . 
FISSURELLA NIGROPUNCTATA. 
Fissurella nir/ropunctala, Sowerbv, Reeve, op. cit. 
Tlab. — S;inta Cataliua, 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 Cataliua, near the coast of Upper California. 
FISSURELLA ASPERA. 
Fissurella aspera, Eschsoholtz, Carp. Rep. 320, [Glyphis.) 
Fissurella cratilia, Gould ? 
Fissurella densedathraia, Reeve? 
Ilah. — Upper California, Lieut. W. P. Trowbridge ; Puget Sound, Dr. Gould.
