 Figures. — The plate (LXIX, figs. 1-4) in the P. R. R. Reports, represents the 

 Salmo f/ibbsii, and not this species. — (See remarks on S. gihbsti.) 



Sp. Ch. — Convexity of dorsal outline rising gradually to origin of 

 first dorsal, declining from thence to the tail. Caudal forlml. Head 

 small, exactly eonlcal, terminating in a pointed snout. Commissure of 

 mouth very slightly oblique. Back of body and head studded with oval 

 and circular spots ; sides and fins, includuig the caudal^ destitute of sjmts. 

 Teeth minute and sharp; a single row on each palate bone, a few on the 

 anterior end of the vomer, and a double row on the tongue. [The fore- 

 going descrijition is deduced from Dr. Gairdner's notes in Eich. F. B. 

 A., p. 224.J The portions italicized in the above summary of specitic 

 characters are those differing strongly from a correct description of the 

 fish taken by Dr. Girardfor this species, and described by me as the >S. 

 gibhsii. 



The description, &c., above quoted is copied bodily from the Report 

 on the Salmonid;e, by the present writer, contained in part 2, twelfth 

 volume Pacific Railroad Reports, and duplicated in the work entitled 

 Natural History of Washington Territory. Since then no additional 

 information has been obtained concerning the fish, although careful 

 inquiries have been made.

Sp. Ch. — (Drawn from Richardson's description and Dr. Gairdner's

 nearly even. Both jaws armed vrith strong hooked teeth, a single row 

 on each palate bone, and a double row on the anterior half of the vomer 

 and on the tongue. The teeth are long, slender, and acute. Lingual 

 teeth longest and most curved, An oblong jjlate on the isthmus 

 which unites the lower ends of the branchial arches rough, with very 

 minute teeth. Sixty-six vertebra? in t!ie spinal column. 



From the colors given by Dr. Gairduer we infer that they were noted 

 from partially exhausted individuals of some species of anadromous 

 salmon. He says: "Back generally brownish purple — red, passing on 

 the sides mt6 ash-grey, and into reddish white on the belly. Large 

 patches of dark purplish-red on the back, dorsal and base of the caudal
