A. scaber , as noted by P. Y. Schmidt (1927, p. 1), is close to A. miacanthus 

 Gilbert and Rirke, which it approaches in the absence of nasal spines, but varies 

 in roughness of head skin, presence of occipital tubercles, pores on head and a 

 greater number of pores in the lateral line, and in other characters. Parti- 

 cularly close to A. miacanthus are examples from Anadyr Gulf, which have the 

 occipital tubercles hardly noticeable and the skin just slightly rough. The 

 papillae are small and hardly noticeable as are the pores on the top of head and 

 spines on occipital. The larger number of LL pores (27-29) and general habitus 

 of the sample allow to confidently call it a deviation from the typical form 

 of A . scaber beringianus Schmidt .

 Artediellus dydymovi gomojunovi Taranetz, 1933, I.e., p. 71 (W sect of 



Bering Sea N to cape Chuckchi) . 



This subspecies recently described by A. Y. Taranetz on material of the 

 1931 and 1932 expeditions is very common in western Bering sea; north of Anadyr 

 Gjlf is rare. Single specimens reach Bering Strait (DALNEVOSTOTCHNIK, 1932, 

 St. 23 (17) and 38 (31).). Often found on rocky gravel bottoms near Koriak land 

 (Cape Olytorsky to Cape Navarin) . Together with Triglops beari and Icelus spatula 

 spatxila composing the basis of the catch. (To 150 examples or more of 

 Artediellus dydymovi gomojunovi m a 15 minute beam trawl haul.) Common on 

 rocky and gravel bottoms but rare on clay and sand where it is found only singly. 

 Temperature range wide (-1.7'' to 2.6"; young to 5.8°), but in temperature sjaelow 

 zero only found as single examples. 



It is interesting to note that this form, as Icelus spatula spatula produces 

 albino variations . For example, some have white spots on the occiput or two 

 small spots on the preopercular, as we found in 10-15% of total among those from 

 Anastashiya (Korykakay gulf) and in the Anadyr cold spot .
