This species is well represented in our material from the Okhotsk, Bering 

 and Chukchi Seas, differing greatly from previously described forms. Nearest to 

 Lycodes knipowitschi Popov (in the mandibular flap, lips, etc.), but differs from it 

 in the well developed scales, characteristic coloring, measurements, etc. Common 

 in far eastern seas, usually on clay bottoms, to 130 meters. 



93. Lycodes knipowitschi Popov 



Lycodes kiipowitschi Popov, 1931, I.e., p. 138 & 152, fig. 1, pi. 2, fig 4 

 (Okhotsk Sea, 40 meters). 



This species, recently described by Popov on the basis of a single young 

 example, 1/ from the Okhotsk Sea, was taken by the DALNEVOSTOTCHNIK 

 expedition in 1932 m the Bering and Chukchi Seas. 



1. Chukchi Sea, st. 32 (26), 66° 45.5' N, 169' 35.5' W (24 miles NE of Cape 

 Unimark). 47 meters, clay mixed with sand, bottom temp. 0.4°, Aug. 17, 1932, 1 

 ex. A. Andriashev. 



2. Anadyr Gulf, St. 52 (45), 64° 21' N, 178° 45' W, 66 meters, smaU coarse 

 gravel covered by clay, Aug. 29, 1932, 2 ex. A. Andriashev. 



Head 23.4 22.6% TL, eye smaU, 13 .2-18 .9% head, snout 30. 7-32. 1% head. Bony 

 interorbital very broad, 1.3-1.7% L, 6.7-7.6% head. Mandibular flaps free, fleshy, 

 low, their anterior lobes rounded. Lower lip with a wide flap posteriorly, an- 

 teriorly broadly adnata. Upper lip slightly widened anteriorly. Upper jaw notice- 

 ably projecting, so its teeth are visible. Posterior end of upper jaw reaching to 

 vertical from posterior end of eye . Teeth on lower jaw (in Chukchi Sea example 

 unequal in length. Main row of 9-10 teeth, outside row shorter (3-4 teeth); the 

 several rowed tooth plate in the anterior portion of jaw is absent. On upper jaw 

 thin, blunt teeth in a single row (9 teeth) which increase in size anteriorly. Inner 

 row not developed, their being but a single tooth on each side anteriorly. Vomer 

 and palatine with strong, conical teeth. Gill rakers 3 plus 1/0 plus 13; rakers 

 of inner row each with 2-3 elements, outer row ending in a single element. 



Body slightly elongated, depth at base of anal 9. 1-12.0% L, predorsal 

 26.6-27.0% L, anterior part of body very Ipng, preanal is 52.0-52.7% L. 



Squamation weak, scales small, sparce, covering only posterior portion of 

 body. Anteriorly the very sparce scales reach to vertical of anus, only a few 

 individual scales occur as far the posterior portion of pectoral. Abdomen and 

 vertical fins naked, only a few scales on the base of latter posteriorly.

Remaining two examples of 105. 1 and 92.5 mm ("varieties or juveniles" of 

 Popov) belong to the above described - Lycodes raridens Taranetz & Andriashev.
