302 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



Of this species Dr. Bean says : 



This whitefish has long been known from Alaska, but it has been confounded with 

 a Siberian species, C. syrok, from which it is really very different. The Russian 

 name is korabati; the Tinneh tribes of the Yukon call it kolokuh. Dr. Dall speaks of 

 it as a common species. He says it is rather bony, and inferior in flavor, and that it 

 is generally used for dog feed except in times of scarcity.

Description. — Head, 4§ to 5 ; depth, 3 J to 3| ; eye, 5£ ; snout, 4£ to 5. 

 D. 11 or 12; A. 11. Scales, 10-72 to 87-9. Maxillary, 3§to4; mandible, 

 2|. Gillrakers, 9 or 10+15 to 17=25 or 26, the longest about 2 in eye. 



Body long ovate, compressed, the dorsal and ventral outlines about 

 equally arched. Head small, slender, and pointed; snout blunt, trun- 

 cate, jaws subequal; maxillary rather long, reaching to vertical of 

 anterior line of eye; the supplemental bone more than half length of 

 maxillary, its width 2£ in its length; mandible long, reaching vertical 

 of posterior edge of pupil. Eye moderate, shorter than snout, lower 

 edge of pupil in a line with middle of upper jaw. Distance from snout 

 to occiput 3i in distance from snout to origin of dorsal fin, which is 

 slightly nearer snout than base of caudal. Caudal peduncle short and 

 deep, its least depth. 2£ in head. Fins rather large; height of dorsal 

 and length of pectoral about equal to length of head; base of dorsal 

 fin not much oblique, short, 1£ iu height of fin ; base of anal fin very 

 oblique, about equal to height of fin or li in longest dorsal ray; adipose 

 fin small, over posterior third of anal; ventrals shorter than pectorals, 

 1 i in head, their insertion under middle of dorsal fin. Tongue with 

 very weak teeth. Gillrakers short and few, usually not more than 25. 

 Scales thin and loosely imbricated; lateral line nearly straight, along 

 axis of body. Color usually quite dark on back and sides, becoming 

 gradually paler below; under parts pale without dark punctulations; 

 fins all more or less black-tipped, caudal darkest. Length about 2 feet. 



Specimens from Lake of the Woods are darker and much deeper in 

 body than those from lakes Champlain and Memphremagog. There is 

 also much variation in the length of the maxillary and in the number 

 of scales in the lateral line. In specimen No. 03, from Lake of the 

 Woods, and upon which our general description is chiefly based, the
