96 Lycenchelys camchaticus (Gilbert & Burke) PI 2, fig 26 



Lycodes camchaticus Gilbert & Burke, Fishes Bering Sea & Kamchatka, 1912 

 p~~89, fig. 34 (Avacha Bay, 682 fathoms) 



Among the deep water collections made by the DALNEVOSTOTCHNIK (1932) 

 were a few examples of Lycenchelys , which according to all characteristics agreed 

 with Gilbert & Burkes description of Lycodes camchaticus but differed in a ventral 

 lateral line, smaller preanal distance and in color Lycodes camchaticus was 

 described from specimens taken in Avacha Bay at a depth of 682 fathoms (1230 

 meters) Our examples are from: 



1 St. 3. Avacha Bay, July 15, 1932. 52" 41' N, 159' 13' E clay sand with 

 rare fine gravel & iron manganese nodules, 800-1000 meters, bottom 

 temperatures 3.1°, oxygen 0.43 (5.75%) deep water Sigsby trawl . 4 ex. 

 A. Andriashev. 



2. St. 5 off Cape Ushin (Bering Id.) July 17, 1932, 55° 25 N 165° 04' E, 

 sand about 200 meters. Beam trawl. 1 ex. A. Andriashev. 



The fact that some of our examples are from the same locality that L . 

 camchaticus was described and are very similar to Gilbert & Burkes description 

 (the lateral line may have been overlooked by the American authors) makes us 

 refrain from describing our form as new . 



Below follows the description of four adults (2 males and 2 female) which 

 show a strong sexual dimorphism.

Head (measured to end of operculum)i/ 14 . 1 - 15 . 8%, TL is slightly compressed, 

 equally sharpens toward the snout. Eye small 20.3-20.4% head, 2.5-3.0% L, 

 snout 25.4-28.2% head, 4.4-5.5 % L. Bony interorbital very narrow 3.0-3.2% 

 head. Structure of ventral surface of head (mandibular flaps, pores, lips) 

 very characteristic of the genus Lycenchelys Gilbert (see figs. 18-19).

Head length measured to end of gill membranes (as measured by Gilbert & 

 Burke) is 15.9-16.9% L.
