The pectoral short, usually not extending halfway to origin of anal; some 

 11-13% of the length. Ventral relatively long, 2.2-2 .6% length, 11 .0-14.0% of head. 



Goicr of our examples poorly preserved, the narrow vertical light bars 

 have almost disappeared. 



Reaching a large size (to 1/2 meter), mature examples not less than 300 mm long. 



89. Lycodes palearis arcticus Taranetz and Andriashev, 

 subsp. nov. (plate 1, figs. 9-10). 



This small cold water form we consider a subspecies of the typical L . 

 palearis , differing from it primarily as follows: 



1. Smaller size of body, (matarmg at 140 mm), a female 250 mm long was 

 ripe . 2 . Large pectoral fins, a larger eye diameter, longer head and other 

 measurements (see description). 3. A much sharper mandibular flap. 4. Coloring. 



Examples belonging to this subspecies were found at many stations in Anadyi 

 Gulf and two examples were taken m the Chukchi Sea. This form occurs as one of 

 the characteristic components of the cold Anadyr biocenosis on clay bottoms to- 

 gether with. Ophiura sarsi and Lumpenus medius, comprising the major mass of the 

 trawl catches. In Anadyr Gulf it was found at depths of 84 to 110 meters, usually 

 at very low bottom temperatures (0.9° to -1.7°).

Head longer than in typical form, 20.3-21.0% of length, eye large 19.0-21.9%, 

 head length (16.0-17.5 in typical form), snout considerably elongated and sharp 

 28.9-34.5% of head. Interorbital narrow, 0.6-1.0% length, 3.0-4.6% head. Mandi- 

 bular flaps separate, thin, higji, particularly anteriorly where they form an 

 anteriorad protruding sharp lobe (plate 1, figs 9-10). Jaw extending to vertical 

 from middle of eye. Distribution of teeth on jaws, vomer and palatine as in L. 

 palearis palearis Gilbert. Depth at base of anal fin 7.8-9. 1% length, predorsal 

 24.4-27.6% length, preanal 41 .2-43.3% length. Lateral line indistinct, ventro- 

 lateral, but posterior portion on mediolateral section of body not always de- 

 tectable, particularly in young. 



Pectoral longer than in other subspecies, reaching half to two thirds the 

 distance to anal origin, 67-80% of head, 13.0-15.6% of length. About five lower 

 rays with free tips. Ventral comparatively long 2.7-3.1% of length, 13.4-15.5% 

 of head.
