Numerous examples of Lycodes with a weakly developed lower pectoral lobe were 

 caught by the DALNEVOSTOTCHNIK (1932) off Beriag Id., at depths of 200-235 meters, 

 sandy bottom, bottom temperature 2.3° (st. 5 and 70 (59)).

Head 18 .4-21 ,2% TL, eye large, 26 . 1-34. 8% head. Snout usually equal to dia- 

 meter of eye, 26.7-30.6% head. Mouth small, upper jaw extends oiily to vertical 

 from front edge of eye or sligjitly farther , Bony interorbital very narrow , 



Teeth on jaws small, sharp, increasing in size anteriorly slightly. Upper 

 jaw teeth in 2 rows, anteriorly a third row of 8 small teeth . Lower jaw anteriorly 

 with 3-4 rows, reduced posteriorly to 2 and 1 row. 2 or 3 slightly enlarged teeth 

 on vomer. Palatine teeth blunt, often tubercle -shaped, about 7 teeth m one row. 

 Mandibular flaps weakly developed, free, m form of low thm folds, which come close 

 together anteriorly. Upper lip thins slightly posteriorly. Lower lip widens slightly 

 posteriorly. Small head pores and sensory cavities on upper and lower jaw are 

 distinct. Nasal tubes well developed, bluish black, about 2/3 diameter of pupil, 

 surrounded by small pores (5-8) extending toward eye. Gill opemngs extend 

 ventrally to level of lower edge of pectoral, or lower . 



Body very elongated, depth at base of anal 6.5-8.9% TL, predorsal 22 .0-24 . 7% L . 

 preanal 33.4-39.1% L. 



Squamati on well developed . Scales small, completely covering body and 

 vertical fins . Anteriorly they greatly decrease in size, extending on nape to 

 line connecting gill openings; laterally extending to pectoral and on the abdomen 

 as far as the ventrals . 



Lateral line hardly visible, ventral. Originates at gill openings, forms 

 lower limit of scales on nape, extending down and back towards base of anal fin 

 but not reaching it; terminating 1/3 of body from tail . Pectoral cut, forming a 

 weak lower lobe (6-7 rays) and is covered with dense skin. Middle 3-4 rays 

 slightly shortened giving the cut a shortened appearance . Shorter than in the 

 typical L . diapterus Gilbert (Oregon) and L . diapterus nakamurae Tanaka from 

 Japan & Okhotsk Seas. Length of upper pectoral lobe 12.0-14.9% L, lower lobe 

 8.9-11.8% L. Ventral slender, 2.2-3.1% L. It is attached at vertical from 

 lower edge of gill openings . 



Coloring: Scales ligjit, surrounding area greyish brown, darker on abdomen 

 and gill membranes. 5-6 light bars across body extending on dorsal fin, widening 

 ventrally in form of/\ . In young examples (to 100 mm) the pattern is distinct. 

 Ventrally lower portions of /\ connected m middle of body by light lines . Dorsal 

 and anal greyish, darker above and posteriorly darkemng to an intensive bluish 

 black color. Ventral weakly pigmented. End of pectoral darker. Usually a dark 

 spot at dorsal base (more distinct in young; in adults the striped pattern is weak 

 and often disappears) .
