Coloring of body pale, grayish green or yellowish. Indistinct light bars 

 across body and dorsal fin. More evident in young examples, almost absent in 

 examples 200 mm long. Back along dorsal and top of head darker. At dorsal 

 usually two light lines, the first connecting the tops of the gill opening . Ventral 

 fin completely light. Anterior portion of dorsal with a black ocellus, distinct 

 in young. Fins are light, not bordered with a darker color. 



Length of our examples from 90 to 250 mm, examples described of six (mature) 

 examples 143-250 mm. L. palearis arcticus Taranetz & Andriashev is much closer 

 to the typical L . palearis of the Bering Sea and probably represents a small light 

 colored arctic worm connected by intergrades with the typical form . The above 

 differences and proportions of body indicate juvenile characteristics (large head, 

 eye, pectoral, etc . ) but are present in mature examples . Here is an example of 

 subspecies formation through neoteny, that is, the ability to reproduce at earlier 

 stages than is usually possible. 



90. Lycodes brevipefi diapteroides Taranetz & Andriashev forma nov. 



(plate I, figs. 11-12)- 



A large number of lycoids related to Lye odes brevipes Bean were found in the 

 eastern Bering Sea (KRASNOARMEIETZ, 1932) and SE of Cape Navarin (KRASNO- 

 ARMEIETZ, 1933) These examples differ from the typical form which is common 

 from the Aleutians south to Puget Sound in a larger number of D & A rays, a weaker 

 developed LI, presence of an indistinct lower lobe in the pectoral and other characters, 

 are identified by us as a separate form diapteroides .
