 a salmon-trout, or cJieicagh, fS. camphellij with hook aud line, which

WARREN'S TROUT. 



Svx. — Sah.io H-arreni. Suckley. Xotices of Certaiu Xew Species of X. A. Sal- 

 niouidte, Xew York, Juue, 1681. 

 Typical specimens 2070, 2073, iu Smithsonian collection of fishes. 



Sp. Ch. — [The largest specimens exammed by the describer were not 

 over 10 inches iu length. They may have been immature individuals of 

 a larger anadromous species, but were labeled " trout" by Dr. Kemierly.J 

 Dorsal outline strongly arched ; its convexity rismg suddenly from the 

 nape, and attaining its height at a point near a line drawn perpendicular 

 to the lateral line aud touching the tips of the pectorals when flattened 

 backward along the sides. Head rather broad ; muzzle .somewhat coni- 

 cal ; jaws equal and rounded. The eyes beneath plane of lateral line. 

 Opercula aud pre-opercula spotted with minute spots of black. Nu- 

 merous stellate and irregular Idack spots, many of which are quite faint, 

 as if obscured by the thickness of the overlying scales; belly white; 

 back bluish or greenish ; dorsal fins aud tail spotted; scales small, (but 

 much larger thau in S. fontiiialis,) compact and very adherent ; when 

 glistening iu certaiu reflections, giving an enameled appearance to the 

 fish. Tail forked. 



Diagnosis. — See text beyond. 



Hab. — Waters of Fraser Eiver, British Columlda, near Chiloweyuck 

 depot. Dr. Kennerly. 



Dr. Kennerly sent home six specimens of this salmon from Chilowe- 

 yuck depot. They are handsome and silvery, appearing as if fresh run 

 fioni the sea. 



The description was drawn fi'om Dr. Keunerly's specimens already 

 spoken of. The largest of these was about 9 or 10 inches long ; the 

 smallest not quite 6. In none were the dark bars of youth vi.sible ; so 

 I have not been disposed to consider them the young of a larger spe- 

 cies of anadromous salmon, although their silvery appearance would 

 incline to that conclusion. They seemed to be more compressed laterally, 

 aud to have greater comparative depth than individuals of the species 

 known as S. iridea, Gibbons ; or of the ^V. masoni, Suckley. The thick 

 glistening scales — ob.scuring to a certain extent the numerous black 

 stelUited spots beneath — serve as another point of dirference betAveen 

 this fish aud S. iridea, {>>. stellattis, Grd.,) iu which the scales seem thick,
