SUCKLEY MONOGRAPH OF THE GENUS SALMO. 145 



uill Still take the bait. At this time it is necessary to fish br-low the 

 (lain, where there is still a very rapid canent, from leakage and over- 

 flow. The brook-trout, <S'. fontinali*!, is taken in the same waters, and, 

 in the stiller waters above, a large lake-trout, there called the iogue, 

 which differs from the Hnlmo confi/m of the northern lakes, by having 

 a more deeply forked tail like the >S'. siskowet of Lake Superior." 



Mr. Harris there makes some interesting remarks on the peculiar 

 deformed appearance which the jaws of certain salmons present during 

 the spawning season.

Sp. Ch. — Mule: The head, measured from snout to nape, is contained 

 about seven and a half tim?s in the total length ; when measured from 

 the same point to extreme edge of operculum it is contained but four 

 and three-quarter times. The point of greatest depth of body corre- 

 sponds to a line drawn from the back down ward, about midway between 

 the tips of the adducted pectorals and the anterior insertion of the ven- 

 trals. The tips of the dorsal and ventrals when flattened backward reach 

 the same imaginary vertical line. Adipose dorsal commences at a point 

 nearly opposite the origin of the last ray of the anal — the tips of both 

 fins extending backward equally far; tail strongly forked, its free mar- 

 gin somewhat waved. Snout somewhat turned up, the lower jaw pro- 

 jecting slightly beyond the upper. A single row of teeth along the 

 anterior half of vomer. Teeth on the premaxillaries rather strong. 

 Size of adult rarely exceeds 10 or 11 inches; body compressed laterally, 

 its greatest depth contained four and a quarter times in total length. 

 Dorsal outline strongly arched, from the nape, the ridge being some- 

 what sharp. Curv'e of belly from origin of ventral fin to that of the 

 last ray of the anal very sharj); from thence to the caudal the upper and 

 lower borders of the peduncle of the tail are almost straight and paral- 

 lel. General color red, dingy along the back, paler on the sides, and 

 fading to jyiwo, white on the belly. Small, irregular, black spots above 

 the lateral line. Pectorals bluish, their tips slightly grayish. Dorsal 

 and ventrals red. Tail slightly spotted. 



Female: Jaws more equal. Snout curled up. Length about the same 

 as that of male, but the depth of the body is not so great, neither is the 

 sharp, hump-like ridge on the back so apparent. 



Colors. — General color red, but slightly darker than the male. In other 

 respects the sexes appear to agree. 



Diagnosis. — The Hnlmo Icennerlyi can be readily recognized by its nar- 

 row, deep body, red colors; the back spotted with black, and the 

 sharply forked tail.
