The following table lists the results obtained by K. I. Panin in the measure- 

 ment of 572 examples from the northwestern part of Anadyr Gulf (KRASNOARMEIETZ, 

 1933, St. 17 & 18).

Navaga are amphiboreal fish (not circumpolar as 

 stated by Jordan & Evermann (1898) and other authors). 

 They are known along the Murmansk coast east of Cape 

 Ob. The subspecies gracilis extend from the Chukchi 

 Sea south to Puget Sound and Korea. We found wachna 

 (Russian for gracilis ?) in Avachin Bay where m June 

 it occurs in considerable numbers m seld (herring) 

 and salmon nets . According to K . A . Vinogradov occurs 

 in Avachin Bay in winter. This was substantiated by 

 a very successful under ice catch made m the winter 

 of 1932/33 . According to local inhabitants, it occurs 

 in April in Providence Bay. In our collections there 

 is a single example from Olytorsky Gulf (PALTUS, 1932) .

In the Bering Sea, treska is common on both coasts, 

 the Aleutians and Commander Ids . The northernmost 

 record from Providence Bay (DALNEVOSTOTCHNIK, 

 St. 20 (14)). Treska were absent from every haul north 

 of St . Lawrence Id . Local inhabitants state that treska 

 fill the bays in the southern part of the ChuJcchi 

 peninsula (Providence Bay, Vusten River, Kuguan Gulf, 

 etc.) in winter (November -December). This fact 



in these localities does not make great migrations and does not move 



do the Atlantic treska. i.'

These statements also apply to the treska of eastern Kamchatka . They do not 

 migrate f^r and merely go from deep water to the coastal region. V. F. Shmidt's 

 data indicate treska eggs are widely distributed; this and the absence of large 

 schools in which fish of this type usually migrate, the narrow continental shelf
