Head 20.9 22,8% TL, eye small 17.2-20.9% head, smaller than snout which is 

 26.5-28 .6% head. Uppei jaw extends to vertical from middle of eye. Lower lip 

 adnate anteriorly, with a very wide lobe posteriorly. Mandibular flaps free, high 

 their anterior edges rounded without anterior lobes. Upper and lower jaws have 

 well developed shallow sensory cavities . Head with many pores having raised 

 edges . Nasal tubes long, almost equal to diameter of pupil witii small pores . 

 Interorbital 5.5-5.6% head. 



No scales. Lateral line single, mediolateral, distinct. With large pores 

 having raised edges . Above LI are individual widely spaced pores . Predorsal 

 27.3-28.3% L, preanal, long, 48.2-49.7% L. Precoral rounded, small 11.5- 

 12 .4% L (m an example 92 mm. is 15 .2% L) . 



Coloring characteristic, remaining the same throughout life as described by 

 N. M. Krapowitch (I.e., 1906, p. 16), Upper part d body and head is dark. Along 

 nape a light line . Ten wide light bars on body extending on dorsal fin. Lower part 

 of body light (yellowish white) . 



According to N. M. Knipowitch this species, a high arctic type, is commonly 

 found below zero, usually below -1° . Most common on clay, though sometimes on 

 sandy bottoms. Hofstenl./ also considers this a high arctic type. It is interesting 

 to note that there is no single wide spread form of the genus Lye odes in tjie 

 Atlantic and Pacific, though this genus is represented in tiie northern part of these 

 oceans by a large number of species (more than 30 in the Pacific). L. agnostus 

 is the only known member of the genus Lycodes which has an uninterrupted distri- 

 bution from E. Barents Sea to the N. part of Bering Sea.

The scalloping of the pectoral is not sufficient to recognize Furcimanus Jordan 

 & Evermann as a separate genus as it varies in L. soldatovi Taranetz & Andriashev 

 and L . brevipes diapteroides Taranetz & Andriashev, and from a weakly divided 

 lobe in this subspecies to the distinct lobes of L. diapterus diapterus, L. diapterus 

 nakamurae and L. macrochir Schmidt, sp. nov., in litt (Okhotsk Sea). 



On the other hand, the Furcimanus series is not natural because its forms indep- 

 endently possess (as if adapted) larger or smaller variations of the lower pectoral 

 lobe, as occurs in other groups . For example, L . diapterus and subspecies has 

 a ventral -lateral lateral line and weakly developed mandibular flaps, whereas L. 

 machrochir Schmidt with a ventral -lateral line has well developed mandibular flaps. 

 This compels us to regard Furcimanus as a genus or subgenus but with the under - 

 standing it is a polyphyletic group which should be identified with a distinct name 

 (for instance, congenus) .
