Body stout, moderately elongate, its greatest depth contained 

 three and two thirds to four times in total length without caudal; 

 caudal peduncle short and stout, its least depth one third of 

 greatest depth of body; head conical, pointed, its length one 

 fourth of total length without caudal; eye small; less than one 

 half of length of snout, and about one seventh of length of head; 

 maxilla slender, its width scarcely one fourth its length, which is 

 one half the length of head; nostrils nearly midway between eye 

 and tip of snout; teeth small, longer on sides of lower jaw than 

 in front, Tomerines few and weak, disappearing in the males; 

 gill rakers usually about 23, of which 14 are below the angle 

 of the first arch; dorsal origin midwaj^ between tip of snout 

 and base of upper external caudal rays, the base of the fin as 

 long as the longest ray, one half as long as the head, the last 

 ray two fifths as long as the longest; adipose fin over the end of 

 the anal, its width scarcely one half its length, which is two 

 sevenths of the length of the head. The anal base is three fifths 

 as long as the head; the longest anal ray is two fifths as long as 

 the head and more than twice as long as the last ray. The ven- 

 tral is under the last rays of the dorsal, midway between front 

 of eye and base of caudal, its length one half the length of head, 

 its appendage one half as long as the fin. Pectoral as long as 

 postorbital part of head. B. usually 17 or 18; D. 11; A. iii, 15 or 

 16. Scales usually 27-146-29, sometimes as many as 155 in a 

 longitudinal series. Vertebrae 66. Pyloric caeca 140 to 185. 



The quinnat salmon is the largest and finest of the Pacific 

 salmon. It ranges from Monterey Cal. to Alaska and eastern 

 Asia, ascending rivers in some cases 1500 miles or farther from 

 the sea. It has been introduced into lakes of New York, but 

 there is no evidence that it has become established in any waters 

 of the state. Possibly better results might be secured if larger 

 fish were selected for the experimental stocking.
