Gymnelis, REINHARDT, Dansk. Vidensk. Sel&k. Afhandl., vn, 131, 1838 (viride). 

 Cepolophis, KAUP, in Archiv fur Naturgesch. 1856, 96 (viridis). 



Body elongate, naked. Vertical fins without spines; ventral fins none. 

 Small conical teeth on the jaws, vomer, and palatines. Gill openings very 

 narrow. No air bladder ; pyloric caeca none ; no anal papilla. Size small. 

 Cold seas. Two or 3 species known: G. pictus, from the Antarctic, and 

 G. viridis, which ranges widely in Arctic waters, and with which the very 

 dubious G. stigma is probably identical. (yvjuvoS, naked; syx^v$, eel.) 



a. Dorsal fin inserted close behind pectoral, its distance from it much less than diam- 

 eter of eye; no ocellus on dorsal fin. VIRIDIS, 2840. 

 act. Dorsal fin inserted an eye's diameter behind pectoral; a large black spot, ocellated 

 with white, on dorsal fin above vent; other ocelli sometimes present. 



STIGMA, 2841. 



2840. GYMNELIS VIRIDIS (Fabricius). 



Head about 6; depth about 13; eye 7 in head. D. 100; A. 80. Snout 

 subconical, longer than the eye; jaws equal; mouth oblique; maxillary 

 reaching beyond eye; teeth rather small, conical, in a single series on each* 

 side, forming a patch anteriorly; distance from snout to vent 2 times 

 length of head. Pectoral rounded, inserted low, its length less than that 

 of head. Dorsal fin inserted close behind pectoral, its distance from it 

 much less than diameter of eye. Body pale, with faint dark cross shades ; 

 dorsal clouded but without black spot; anal dusky. Arctic seas, Alaska 

 to Greenland and Nova Scotia; abundant in the Arctic waters south to 

 Unalaska and Bristol Bay, where specimens were taken in shallow water; 

 our specimens from Bristol Bay. 



Ensign H. G. Dresel records 1 small specimen (No. 28636, U. S. Nat. Mus.), 

 badly preserved, obtained by Mr. Newton Pratt Scudder in Davis Straits, 

 July, 1879. Length 100 mm. D. ca. 97 ; A. ca. 80. In this specimen the 

 maxillary does not extend to the posterior margin of the eye, which is com- 

 paratively very large. Its diameter is longer than distance from tip of 

 snout to orbit, and is contained 4 times in head. Head 7 in total length; 

 depth 12. Pectoral 2 in head, (viridis, green.)

 above vent ; 2 or 3 other ocelli sometimes present ; head and nape with 

 small white spots; body with faint dark shades and bands. Otherwise
