is likewise sub-concave. The ventrals are well developed and inserted opposite the middle of 
the dorsal. The pectorals are longer than the ventrals, and, like the latter, conspicuously 
developed. The formulae of the rays is as follow: 
Br. 13 : 12 ; D 13, 0; A 14 ; C 5, 1, 9, 8, 1, 4 ; V 10 ; P 14. 
The anterior two rays in both the dorsal and anal fins are rudimentary ; the accessories in 
the caudal may prove more numerous, since our investigations were conducted upon a prepared 
skin. 
The scales are of medium size, suh-elliptical, longer than deep, and somewhat irregular in 
the lateral line, which runs nearly straight along the middle of the flanks. The dorsal scales 
are a little smaller than the abdominal ones; the concentric stria in all of them being obliterated 
upon their posterior margins. 
The ground color of the dorsal region is olivaceous, clouded with bluish brown undefined 
patches, and scattered over with roundish black spots, of which a few only are observed below 
the lateral line. The sides and inferior region of the body are unicolor, yellowish brown. The 
dorsal fin, the adipose, and the caudal are densely spotted with black, whilst the inferior fins 
are unicolor. The upper surface of the head is bluish black ; the sides being yellowish brown, 
like the flanks. 
The above description and the figure annexed thereto were made from a preserved skin. 
The specimen, which is two feet and two inches in total length, was caught at Fort DaPes, 
Columbia river, and preserved by Dr. Geo. Suckley, under Gov. I. I. Stevens. The following 
is from Dr. Suckley’s notes : 
“ Fort Dalles, 0. T., April 5, 1855.—A female salmon trout; weight five pounds ; length 
twenty-six inches, girth eleven inches ; specimen of average size ; was full of roe nearly 
mature. Tail and upper fins olive (yellowish), spotted with round and oval black spots, about 
two lines in diameter. Upper part of head and hack rich olive ; scales reflecting bright silver. 
A dark pink or salmon colored hand extends its whole length on each side both above and 
below (including) the lateral line. This last may he a post mortem change. Belly silvery 
white. Iris golden. Chin white. Dorsal fin same as tail. Ventrals and anal yellowish and 
vermilion ; pectorals darker. Flesh reddish cream colored. Walla-Walla name, Shooshines ; 
Wasco name, Icquansek (last syllable gutteral ‘ighk’).” 
This quotation shows how much the coloration may he altered on specimens either prepared 
as skins or else preserved whole in alcohol.
