of Primoria and Japan, omitting the northern bays of Nivel (which is the northern 

 part of Tartar Strait) and the southern Kuril Islands . Of special interest is the 

 find of ivasi in East Kamchatchan waters by V. B. Bool and K.I. PanirtJ/ in 

 September of 1933 in Kronotak and Avacha Bays. In 1934 ivasi was aeam noticed 

 on the East coast of Kamchatka in August, September and October.—' Single 

 examples were sometimes found in early November and the catch exceeded a 

 hundredweight . 



The explanation for the presence of this species m Kamchatka brought about 

 some discussion. V. B. Bool and K. I. Panin (1933, 1 .c.) postulated the 

 existance of a northern race which heretofore was not known commercially. 

 G. U. Lindbergh./ considered the waters of Kamchatka and the Commander Ids. 

 the normal northern limit of ivasi . L . S . Bergz/ considered the appearance 

 of ivasi in Kamchatka as the natural outcome of fish and other organisms 

 migrating northward, as a result of the "warming of the arctic and subarctic 

 waters (firstnoticedapproximately in 1920 and earlier)." 



However, an accepted view put forth by K. I. PamnV states that ivasi 

 extends its feeding migrations to the north in warmer years and reaches as far 

 as the east coast of Kamchatka . The periodic occurence of ivasi in the north 

 is correlated with the warm Kuro-Shio current and this fact is supported by 

 hydrographic data. In recent years (i933 and especially 1934) the appearance 

 of ivasi was characterized by increased water temperatures. However, in 1935, 

 data by M. Y. Beckman indicated the water temperature dropped, which is 

 also supported by the fact no ivasi were found in spite of a special search. 



The two specimens presented by K. I. Panin (from Petropavlovak Bay, 

 Oct. 25, 1934) have the following measurements: D( total) 18-19, A 18-19,
