 [ ? Corcgonus riclwrdanuii CiuXTiiEK, Cat. Fish. Brit. Mus., vi, 185.] 

 [This species, described by Dr. Giiutber iu 186G, has been cousidered identical witL tbe 

 common Whitefisb of tbe Great Lakes, G. clupeiformis, bnt tbe common Wliitefisb bas not been 

 taken in Alaska or "Arctic ISTorth America," so far as we know. It is bigbly probable tbat a 

 re-examination of tbe types of richardsonii will show tbat tbey are tbe species now bearing 

 Kennicott's name.— T. H. Bean.] 



29904. (238.) Saint Michaels, Canal, November 8, 1880. 

 ■^-Unusual size for this species bere. I am told tbat tbey get mucb larger in some lakes at Nulato. 

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



32893. 32894, 32903, 32904. 

 (Notes on original Nos. 131 to 134.) 



Small-headed Whitefish from canal near Saint Micbaels, wbere tbey are very numerous just 

 after tbe canal freezes over in tbe fall, wben many are speared and trapped in wicker traps. Tbe 

 latter metbod is rarely practised, bowever, and only by natives who bave lived on tbe Yukon. 

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

 of the same kind and about one-third as many of tbe large Sboveled-jawed Whitefisb so numer- 

 ous at tbe Y'ukon mouth in winter — Russian name Nelma. 



Upper surface dark browni.sh olive, becoming satiny white on flanks and abdomen and over 

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

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

 i.sh-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 portion of the caudal. 



This species is common at different seasons, both along tbe coai?t of Bering Sea and in the 

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

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

 just before ice makes iu the large sti"eams, 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 Whitefi.sb taken in gill-nets on the north coast of Sil.>eria iu Augu.st, 

 1881, which I considered to be this species. 



In spring, during June, the Whitefisb of various species run up tbe smnll streams.
