their enoinies by crowdint*' the most sliaHow brooks, where they are easily 

 taken with a haud-iiet. Tlie Indians here call them Ui-mia. About the 

 1st of September they disappear quite suddenly." Again he writes, Sep- 

 tember! : ^'Have been fishing as usual, and with good success; caught 

 a sahnon-trout, or cJiewafjh, fS. camphelllj with hook and line, which 

 Aveighed eight i^ounds. The little red salmon have nearly disappeared, 

 and those left are tiu-uing white, undergoing the same change which takes 

 place later in the season with the Icoichuts.''^ Kennerly, (in mss.) 



34. SALMO WAEREXI, Suckley. 



WARREN'S TROUT. 



Syn. — Salmo icarreni, Suckley. Notices of Certaiu New Species of N. A. Sal- 

 uiouidaj, New York, June, 1861. 

 Typical specimeus 2070, 2073, in Smithsonian collection of fishes. 



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

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

 a larger anadromous species, bnt were labeled " trout" by Dr. Kennerly. j 

 Dorsal outline strongly arched ; its convexity rising suddenly from the 

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

 to the lateral line and 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 i)lane of lateral line. 

 Opercula and pre-opercula spotted with minute spots of black. ]Su- 

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

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

 back blaish or greenish ; dorsal fins and tail spotted; scales small, (but 

 much larger than in S. foutinaUSj) compact and very adherent ; when 

 glistening in certain reflections, giving an enameled api^earance to the 

 fish. Tail forked. 



Diagnosis. — See text beyond. 



Hab. — Waters of Fraser Eiver, British Columbia, near Chiloweyuek 

 depot. Dr. Kennerly. 



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

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

 from the sea. 



The description was drawn from Dr. Kennerly'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 visible ; so 

 I have not been disposed to conf^ider 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, 

 and to have greater comparative depth than individuals of the species 

 known as S. iridea^ Gibbons; or of the 8. masoni, Suckley. The thick 

 glistening scales — obvscuring to a certain extent the numerous black 

 stellated spots beneath — serve as another point of dift'erence between 

 this fish and S. iridea, {S. steUatns, Grd.,) in which the scales seem thick.
