bottoms, in depths of 33-81 meters in temperatures a little above 0' . 



Our examples are without nasal spines . Skin on head smooth, pores little 

 developed, cirri almost completely obsolescent. No tubercles on occipital. LI 

 with 21-22 pores. 



This form is known from the Okhotsk Sea and Western Bering Sea. Absent 

 in Anadyr gulf and to the north. In the Japanese sea probably replaced by a 

 similar form described by V. K. Soldatov as Artediellus aporosus . 



41. Artediellus scaber beringianus Schmidt 



This high -arctic species is very common along the northern coasts of Asia 

 where it is known from the Barents sea to Bering Strait as a subspecies described 

 by P . Y . Schmidt, beringianus from the northern part of Bering Sea (Tkachen Bay) . 

 Our collections of the subspecies beringianus Schmidt show that it is common in 

 the Chukchi sea northward (70° 25 N, 172° 10' W, west of Herald Bank) and to 

 the south to Anadyr Gulf and Cape Navarin. Further south it is absent and re- 

 placed by the pacific representatives of the genus Artediellus (A . miacanthus 

 Gilbert & Burke and A. pacificus ochotensis Gilbert & Burke). 



Common at depths of 31 to 55 meters on sandy clay bottom at negative 

 temperatures or close to 0° (-1 .6 to 0.4°) . A few examiDples deviating from the 

 usual form toward A. miacanthus Gilbert & Burke were caught at great depths 

 (to 93 meters) off Cape Ginter and Navarin in higher temperatures (1 . 7-2 . 1*) . 



P 20-23 LI 25-29. 



Nasal spines absent, occipital tubercles low, weaker developed than in 

 typical form. Skin on head granulated with small popillae which occur to I D. 

 Though the granulations vary it is characteristic that they do not extend beyond 

 the first dorsal; often weakly developed as in an example from southern Anadyr 

 Bay wherein the papillae are often absent . 



Cirri on head and upper part of body numerous and well developed. A long 

 cirrus always behind the eye; also on skin covering occipital tubercles and 

 posterior to them . Cirri on preopercular, opercular and posterior end of lower 

 jaw. Above LL is a row of cirri which become shorter posteriorly and less 

 branched. Number varies, reaching vertical from end of ID and even to middle 

 of 2 D, but sometimes weakly developed there . In addition to granulations on 

 top of head are pores with raised lips . First dorsal high, ends of rays free and 

 a black spot on posterior end of fin. Some examples have a light line on the nape 

 which reaches to the preopercular spines .
