CoREGONUS KENNICOTTII Milner. WMtefisli (Mulcsun of Eussians; Kau-oM-tu of 

 Esk). 

 [ ? Coregonvs richardsonii Guntpier, Cat. Fisb. Brit. Mus., vi, 185.] 



[This species, described by Dr. Glinther in 1866, has been considered identical with the 

 common Whitefish of the Great Lakes, G. clupeiformis, but the common Whitefish has not been 

 taken in Alaska or "Arctic North America," so far as we know. It is highly probable that a 

 re-examination of the types of richardsonii will show that they are the species now bearing 

 Kennicott's name. — T. H. Bean.] 



29904. (938.) Saint Michaels, Canal, November 8, 1880. 



Unusual size for this species here. I am told that they get much larger in some lakes at Nulato. 

 32852. (55.) Saint Michaels, spring, 1877. Blunt-nosed Whitefish. 

 32893, 32894, 32903, 32904. 



(Notes on original Nos. 131 to 134.) 



Small-headed Whitefish from canal near Saint Michaels, where they are very numerous just 

 after the canal freezes over in the fall, when many are speared and trapped in wicker traps. The 

 latter method is rarely practised, however, and only by natives who have lived on the Yukon. 

 These specimens were taken the 1st of November, 1878, and in the same lot were many others 

 of the same kind and about one-third as many of the large Shoveled-jawed Whitefish so numer- 

 ous at the Yukon mouth in winter — Eussian name Nelma. 



Upper surface dark brownish olive, becoming satiny white on flanks and abdomen and over 

 all a steelish-blue luster above and silvery below. Pectorals, ventrals, and anal dark-bluish black ; 

 sometimes the black is only on the outer. portion of the pectorals. Dorsal and caudal brown- 

 ish-olive, with darker margins often nearly as dark as the lower fins, and sometimes the dark color 

 occupies nearly all the dorsals and a large jiortion of the caudal. 



This species is common at different seasons, both along the coast of Bering Sea and in the 

 Yukon and Kuskoquim Eivers. They run in considerable numbers up the large rivers in the first 

 part of winter for the two or three weeks following the run of Lampreys. They are common also 

 just before ice makes in the large streams, and many are taken in gill-nets, although very few are 

 ever secured in fyke-traps for some reason. 



I also saw a number of Whitefish taken in gill-nets on the north coast of Siberia in August, 

 1881, which I considered to be this species. 



In spring, during June, the Whitefish of various species run up the small streams.
