pectoral to light spot. Males have small uniform scales throughout (in an example 

 193 mm. at end of pectoral in 10 mm. are 15 scales). Anteriorly scales reach only 

 to dorsal origin, leaving nape and back in front of dorsal naked. Gill covers 

 without scales. On abdomen small scales at pectoral base. Base of ventral with 

 only a few scales. No scales on pectoral. On dorsal and anal, smaller scales than 

 in female. Lateral line quite distinct, ventral. From gill 

 opening curves down and back, wavy over anal fin and dis- 

 appears posteriorly. In Gilbert & Burke description, 

 nothing is said about the lateral line and it is not shown 

 on their plate. Anal and dorsal not high. Pectoral 6.8- 

 7.4% L. In females it is covered thick skin, has rounded 

 edges and consists of 14 rays, only the lower 4-5 with 

 protruding tips . Males have 17 rays in pectoral, covered 

 by thin skin with tips c }nsiderably protruding. Ventral 

 in females is short, 1.4-1.6% L, not extending to base of 

 pectoral, inserted anterior to line connecting lower edges 

 of gill openings . Males have ventrals considerably 

 longer, 2.6-3.2% length, extending to base of pectoral; 

 inserted on line connecting lower edges of gill openings. 



Color (in life) uniform, greyish purple, reflecting 

 blue green, without spots or lines . Darkens ventrally, 

 acquiring a bluish black color on lower part of head and 

 gill membranes . Scales are lighter than surrounding 

 skin. Dorsal, anal and ventral of the same color, greyish 

 purple . Color of pectoral characteristic, its base and 

 edges black, middle a bright greenish blue color; on 

 the inner edge of fin this light area is smaller, crescent - 

 shaped. In formalin and alcohol examples the dis- 

 tinctness of this spot is lost.

Description is of two males (190 and 193 mm) with 

 weakly developed gonads and two females (220 and 257 

 mnT>with well developed eggs. The fifth example (from 



Bering Id.) is a young male 124 mm. TL whose sex has not been determined due to 

 little development. It appears intermediate between the sexes and so corroborates the 

 correctness of identifying our sexually differing examples to the same species. Sexual 

 dimorphism is greater developed than in other members of the genus Lycenchelys 

 (i.e., Lycenchelys J ordan! Evermann & Goldsborough and L . hippopothamus Schmidt) . 



Our examples found together with other representatives of the deep water fauna 

 ( Chionoecetes angulatus , Spirontocaris biunguis , Brizaster townsendi , Ophi ophthalmu s 

 nordmani, etc.) at the Commander Ids. in shallow water (as does L. camchaticus ) of 

 the lower part of the sublittoral zone.i'
