CH.-Body elongated, compressed, fusiform in profile; dorsal profile but slightly arched; snout rounded, the jaws sub-equal; maxillary gently curved, dilated posteriorly, and extending to a vertical line passing slightly behind the orbit; anterior margin of dorsal nearer the extremity of the snout than to the insertion of caudal fin; colors of the head and back, in the fresh specimen, rich dark olive green, profusely DECEMBER, 1858. 1 ANN. LYO. NAT. HIST. VOL. VIL dotted with roundish black spots, the scales in certain lights showing bright silvery reflections; sides below the lateral line are usually unicolor, of a yellowish white; inferior fins unspotted; tail and upper fins yellowish olive, profusely spotted with round and oval spots of black, each spot being from one to two lines in diameter, and completely isolated from the others, not confluent as in some other species; caudal fin moderately lunated, not forked; head small; teeth small, and very numerous, especially on the labials; length of the full grown adult rarely exceeds 2 feet. Habitat.-The Columbia River and its larger affluents. The species is apparently not anadromous, but seems to remain in the fresh waters throughout the year. The typical specimen upon which the foregoing description is based, is a single skin contained in the Smithsonian collection, Cat. Number 940-that of a female obtained by the present describer, at Fort Dalles, Oregon, April 5th, 1855. The species is known to the Walla Walla Indians as the Shoo-shines, and to the Wascos by the name of Ic-kwan-eek. Mr. Girard, mistaking the specimen for the S. tsuppitch of Richardson, figured and described it as belonging to that species. Upon his attention being called to several marked discrepancies between the account given by Sir John Richardson of the S. tsuppitch, and certain characteristics of the specimen from Fort Dalles, he at once coincided with me in considering the two species distinct. According to Richardson the S. tsuppitch has the dorsal, anal, and caudal fins destitute of spots, and the tail forked. The present fish, on the contrary, has the tail but moderately lunated at its extremity; and the dorsal fins and tail are profusely spotted with black. These prominent differences, besides many others less striking, have been deemed sufficient to settle the question of non-identity of the two species; and as no recorded description seems to refer to the present salmon, it is now presented as a new species under the name Salmo Gibbsii, in honor of my valued friend George Gibbs, Esq., Geologist to the N.
