HABITS OF THE OUANANICHE 21 



lives much on small fish, and, unlike the sea-salmon when the latter 

 is in fresh water, is continually feeding. In some specimens I have 

 found a few teeth on the hyoid bo,ne, though Jordan and Gilbert 

 (Synopsis of ilie Fishes of North America, 1882, p. 311), following 

 Gunther, give the absence of hyoid teeth as a characteristic of 

 the genus Salar. The number of spinal vertebrae is 59-60 ; of cce- 

 cal appendages I have counted from 50 to 60 in different specimens. 



" There are 120 rows of scales along the lateral line, 11-12 in a line 

 from the edge of the adipose fin to the lateral line, which, if con- 

 tinued, would pass just above the pupil of the eye, and is well 

 marked. 



" The fins are proportionately much larger than in the sea-salmon, 

 especially the tail, which is deeply forked in the young fish, but 

 only slightly lunate in large adults. In a five-pound specimen it 

 will have a spread of seven or eight inches ; in a three-pound fish, 

 six inches. The dorsal is high and broad, the pectorals long. The 

 adipose fin is unusually large. 



"The eye is remarkably large, about three-quarters of an inch in 

 diameter in the adult, with a pupil a quarter of an inch in diameter. 

 These measurements are much greater than in the sea-salmon of 

 fifteen to twenty pounds' weight. In the young fish the back is of 

 a bluish-olive when just out of water, turning into a silverish steely 

 blue, which changes to silver below the medial line. The belly is pure 

 white. The back is thickly maculated with black oval spots, not 

 vermiculated, as in trout. On specimens under a half-pound there 

 are no X marks on the sides, but seven small, round, bright- scarlet 

 spots, evenly spaced along the medial line, with an additional one 

 just above the pectoral fin. The dark-blue parr-bandings are eight 

 in number, and about three-eighths of an inch wide ; the head is 

 deep bluish green, inclining to black ; the gill-covers silver, with 

 olive and green shading. Upon the operculum are two or three ir- 

 regular, dusky olive, purple, and green patches, and two or three 

 deep black, perfectly circular spots of small size. The throat and 

 branchiostegals are white, shaded with dusky gray, inclining to 

 lead -color. There are some blackish spots along the base of the 

 dorsal, but none on the tail. The adipose fin is blackish-blue. 



" In the fresh-run adult the color runs from deep black on the 

 back, through bluish green on the sides, to silver green at the medial 

 line, and silvery white below that. When the fish is just out of the
