Okhotsk Sea. On the east coast of Japan (south of Tokoyo) it is represented by 

 the closely related Z. bathybius (Gunther). Our example from Avacha Bay from 

 about 1000 meters (DALNEVOSTOTCHNIK, st . 3) . 



D VI, 11 A 10 P 18 LI. 16-18. 



Total length 47 mm . In percentage of body without caudal, depth of body 

 21.1, head length 36.8, predorsal 38 .2, preventrai 30 . 3, preanal 55.3, depth 

 of caudal peduncle 6.1, pectoral length 31.6, ventral length 14.0. In percentage 

 of head length, snout 25.0, eye 16.4, length of preopercular spine 37.8, 

 upper jaw 37.2, lower jaw 44.3. 



Upper preopercular spine slightly curved, long, just touching gill cover 

 End of spine not covered with skin . No hooks on spine shaft (as in Z . bathybiu s 

 (Gunther)) . A pair of short adherent posterior pointing spines on nape . A short 

 scapular spme . Nasal spines undeveloped. Lower jaw sharply protruding. On 

 upper jaw extending to preopercle are six large sensory pores. Smaller pores 

 around eye and on interorbital . Four large pores on lower jaw, anterior pair 

 united into a single larger one . Large pore below each preopercular spine . 

 Above the LL pores are smaller and irregularly placed pores. Small teeth on 

 jaws, weak on vomer and none on palatine. Color a uniform gray without spots 

 or bars, darker below. Fins dark. 



39 . Artedlellus pacificus ochotensis Gilbert and Burke 



In Bering Sea reported by P. Y. Schmidt (1927, p. 3) to 6r 08' N and by 

 A. Y. Taranetz (1933, p. 70) in the southern part of Anadyr Gulf. Our examples 

 from Imatra Bay (North part of Glyubokaya) and in southern part of Anadyr Gulf 

 (Cape Ginter) at depths of 40-81 meters, on sand, temperature 0.3 to 2.1°. 

 Absent in northern part of Anadyr Gulf. 



P 20-23 LL (25) 27-29 



Nasal spines blunt, hidden in skin, but developed. Skin of top of head smooth 

 without tubercles. Pores behind eye and on occiput well developed with raised 

 edges . Cirri on occiput, behind eyes, opercular, preopercular and angle of lower 

 jaw but more weakly developed in the examples from Avacha Bay and regions fur- 

 ther south; which bring that material slightly closer to A. pacificus from the 

 eastern Bering sea. 



40 . Artediellus miacanthus Gilbert and Burke 



In rJie collections of the DALNEVOSTOTCHNIK are two examples from SE of 

 St. Lawrence Island at Sta. 43 (36) and from Anadyr Gulf at Sta. 57 (49) on sandy
