The typical form of Icelus uncinalis Gilbert & Burke was taken in north 

 eastern Kamchatka (off Cape Africa) and the coast of Koriak land (to 61''N). 

 In reviewing the Pacific species of two horn Icelus, I find the following forms: 



1 . Icelus uncinalis uncinalis Gilbert & Burke - -Bering Sea 



2. Icelus uncinalis crassus Andriashev, subsp, nov. - Okhotsk Sea 



3. Icelus uncinalis stenosomus Andriashev subsp. nov. -N. Japan Sea 



4 . Icelus uncmalis spatula ochotensis Schmidt . -Okhotsk Sea, region of 



Shantar Ids. and lona Id. 



5. Icelus spatula bispinis Andriashev subsp. nov. -Okhotsk Sea 



6 . Icelus spatula spatula Gilbert & Burke, see below

This form is widely distributed in the arctic sea from Novaya Zembla to the 

 Chukchi Sea and probably Greenland; in the Bering Sea south to Avacha Bay . 

 Our specimens (over 200) are from the Northern part of Bering Sea and the Chukchi 

 Sea from depths ranging from 20 to 130 meters (usually 50-70 meters) and tem- 

 peratures around 0" (usually -0.8° to 2.8°) on rocky bottoms, or with a mixture 

 of gravel. They were much rarer on sand and clay bottoms . The analysis of 

 distribution can be found in my works referred to above .

Stelgistrum beringianum Gilbert & Burke, 1912, I.e., p. 52, fig. 9 (Petrel 

 Bank, Aleutian Ids . , 43-52 fath); Andriashev, Zool. Anz., 1935, vol. 

 Ill, heft 11/12, p. 290, Cape Olytor sky, 32-34 meters, synon.). 



This species was described(by Gilbert & Burke) from the Aleutian Ids . and 

 is also known from Bering Id. (T. Bean & B. Bean, 1896 as Artedius lateralis) . It 

 was recently found off Cape Olytorsky (A . Andriashev, 1935) . In the Okhotsk and
