SALAR, Yalone. 
Gen. Char. —All the characters of the salmons, but differing from them as well as from the genus Fario in being provided 
with a double row of teeth upon the shaft of the vomer, whilst the front of that same bone is smooth and toothless. 
Svn. — Salar, Valenc. in Cuv. «!y Val. Hist. nat. des Pois. XXI, 1848, 314.— Grd. in Proc. Acad. Nat. Sc., Pliilad. VIII, 
1856, 219. 
There are other trouts, spotted or speckled, which are met with in brooks and creeks, resem¬ 
bling more the “ brook trout,” properly so called, than any of the lake trouts. These constitute 
tjie third subdivision of the genus Salmo, to which the name of Salar has been applied. 
1. SALAR LEWISI, Grd. 
Plate LXII. 
Spec. Char. —Body rather thickish upon the middle region ; head moderate, constituting a little less than the fifth of the 
total length ; maxillary gently curved ; its posterior extremity reaching a vertical line drawn immediately behind the orbit. 
Anterior margin of dorsal fin a little nearer the extremity of the snout than the base of the caudal fin. Ground color of the 
upper region bluish grey, of the inferior region orange or yellow. The back, peduncle of the tail, dorsal, adipose and caudal 
fins are spotted with black. The belly and lower fins are unicolor, a deep orange hue existing along the rays, and also in the 
shape of a dot upon the abdominal scales, and which disappear in alcohol. 
Syn. —Salar leivisi, Grd. in Proc. Acad. Nat. Sc. Philad. VIII, 1856,210 .—Salmo lewisi, Grd. Mss. 
The general aspect of this fish is rather thickest, though the aspect of the body is, upon the 
whole, elongated, with a sub-fusiform outline. The body is quite compressed and the back sub¬ 
rounded ; the greatest depth, taken in advance of the dorsal fin, is contained four times and a 
half in the total length, whilst the least depth, on the peduncle of the tail, is a little less than 
the half of the greatest depth. 
The head, which is of moderate development, is contained five times and a half in the total 
length ; it is sub-conical in shape, rounded anteriorly ; both jaws sub-equal, the lower one 
protruding very slightly beyond the upper. The mouth is proportionally large, the free 
extremity of the maxillary extending to a vertical line drawn posteriorly to the orbit. The 
maxillary itself is slender and slightly curved. The teeth are comparatively small; the largest, 
as usual, are on the dentary and the tongue, the next in size on the shaft of the vomer and 
pterygoidians, and, finally, on the premaxillaries and maxillaries, where they are almost
