LYCODOPSIS, Collett.

 teurynnis, Lockington, Proc. U. S. Nat. Mus., 1x79, 326. 



Zoarceoids with body elongate, eel-shaped, covered with small, smooth, imbedded scales. 

 Head large; snout broadand long; interorbital space very narrow; month large, horizontal: 

 teeth conical, thoseof the upper jaw in a single row, those of the lower in a band in front, 

 the inner series enlarged, larger than the upper teeth; no teeth on vomer or palatines. 

 Ventral fins very small: vertical tins continuous, without spines. (Collett.) 



This genus is represented by one or two species from moderately deep water off the 

 coast of California, Oregon, and Washington.

Gymnelis, Reinhardt, Dansk. Vidensk. Scl.sk. Afhandl., vn, 131, is:;s (type, Ophidium viride, Fabrieius). — 

 GONther, Challenger Report, xxn, 18s", si. 



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; pylo- 

 ric creca none; no anal papilla. Size small. Arctic seas.

Gymnelis pictu8, GtJNTHER, Cat. Fish. Brit, Mus., IV, 1862, 324. 



Height of body one-half the length of the head, which is contained about 0J times in 

 the total length; snout subcorneal, 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 2J times length of head. 



Pectoral rounded, inserted low, its length less than half that of the head. Dorsal com 

 mencing over posterior third of pectorals. 



Radial formula: D. 100; A. 80. 



Color, brownish, usually with dark transverse markings, but sometimes unspotted. 



This species has been found in abundance in the Arctic seas, from Alaska to Nova Scotia. 



MELANOSTIGMA, Gunther. 



Melanostigma, GOnther, Proc. Zool. Soc. London, lssi, 20; Challenger Report, xxn, 1877,82. 



This genus agrees with Gymnelis and Maynea in the absence of ventral fins, and tech 

 nically may be distinguished from both by the much more elongate teeth, which in the jaws, 



as well as on the vomer and palatines, stand in a single scries. However, there are other 

 striking differences, which will be mentioned in the subsequent description.
