of a large number of trout taken by me in Lake Southerland, only two or 

 three specimens of this form were procured, and they were all of small 

 size, and I did not understand that it was ever obtained of much greater 

 dimensions. This could not be the fault of the lake, which is exceedingly 

 deep, and nearly 3 miles in length. It is a gamey fish, takes the fly, leaps 

 .out of water, and is a good fighter for its size." (Meek.) . ': 



Length about 10 inches. 



Known only from Southerland Lake, Washington, where 2 or 3 speci- 

 mens (only 1 of which .was preserved) were taken by Professor Elliot in 

 1898. (declivus, steep; /rows, forehead.)

 (SPOTTED TROUT OF LAKE SOUTHERLAND.) 



Head3.86;* depth 4.79; eye5-.89; snout4.13; maxillary 1.78; scales 146; 

 D. 10; A. 11; branchiostegals 10 or 11. Body elongate, not much com- 

 pressed; head short, maxillary rather broad, not extending far behind 

 orbit its greatest width 4| in its length, in some specimens about 5^, a 

 slight curve downward under the eye; dentition not so strong as in the 

 Speckled Trout of Lake Crescent ; gill-rakers rather long, longer than in 

 the Speckled Trout, but less so than in Blue Back of Lake Crescent; pec- 

 toral in head, 1.88; ventral 2.24; origin of dorsal midway between tip of 

 snout and base of caudal, or slightly nearer tip of snout; origin of ven- 

 trals under first to third dorsal rays; margin of dorsal fin convex, its 

 base 1.32 in longest ray ; snout bluntish. Color in alcohol, dark steel-blue 

 above, paler below, becoming nearly white on the belly ; back, sides, and 

 head profusely spotted with black; some specimens with black spots on 

 the belly aud 011 all fins; pectorals and ventrals usually without spots; 

 upper half of lower jaw black, red under dentary bones. The life colors 

 are given by Professor Elliot in the following note : 



"This beautiful species is exceedingly gamey, takes a fly readily even as 

 late as October, is a great leaper when hooked, and fights a Tontrance. In 

 appearance it resembles Salmo gairdneri crescentis of the neighboring lake, 

 being fully as brilliantly colored, but can be at once distinguished by its 

 orange or orange-red fins, red on the jaw, and the number and blackness 

 of its spots, and darker back and top of head. In general appearance 

 there is not the slightest similarity between this species and the spec- 

 imen from Boulder Creek. At no stage of its existence that I have seen, 

 from fingerlings to fish weighing over 4 pounds, is there any silvery 

 luster, but the colors are all bright-hued, some even metallic. It is one of 

 the most active of its tribe, and I have had them leap after taking the fly 

 in such quick succession, and with such rapid dartings about the lake, 

 that it was impossible to imagine where they would next appear. I be-
