part of the orbit, its greatest width 7 in its length ; about 

 24 teeth on maxillary ; teeth on jaws vomer and palatines large, 

 the dentition much stronger than in specimens of S. g. crescentis 

 of same size ; maxillary nearly straight in the larger specimen, 

 but some curved in smaller specimen ; mandible very strong ; 

 opercle very broad and contains the eye \y 2 ; preoperculum 

 narrow, less than diameter of the eye ; gill rakers very short 

 and thick ; last ray of dorsal less than half longest rays, third ray 

 longer than base of fin ; when depressed, second and third ray 

 tips reach beyond middle of last dorsal ray ; pectorals, if in 

 head ; ventral s, 2^. Color much as in S. g. crescentis, except 

 lighter. Head, body, and tail profusely spotted with black 

 spots ; ventrals and pectorals dark. No. 2036 has fewer spots, 

 none on anal and pectorals. The anterior part of upper jaws 

 very dark, darker than in the larger specimen. This species 

 differs from S. g. crescentis in being much more slender, its back 

 much less elevated, head more slender and pointed, gill rakers 

 shorter, maxillary straighter, narrower, and longer. The general 

 color pattern is the same, except that this species is less spotted 

 and lighter. No red on the under jaw, the dentition is much 

 stronger in this species than in crescentis. 



"This is a deep water fish, keeping always near the bottom. 

 Lake Crescent is of great depth, in some places over seven hun- 

 dred feet, and doubtless much more in others not yet ascer- 

 tained. The present species, unlike other trout, does not come 

 to the surface, as I was informed, at any season of the year, 

 and will not of course take a fly, or indeed a spoon, or any 

 kind of lure. The only way it can be captured is by set lines 

 sunk within a foot of the bottom, and it seems that there are 

 only a few places in the lake where it can be caught even by 

 this means. The specimens obtained were procured at a depth 

 of about two hundred feet. While it is a brightly colored fish, 

 it lacks some of the iridescent hues of .S". g. crescentis, and con- 

 sequently is less attractive in appearance. It is known as the 

 long nose, or long headed trout." (D. G. E. )
