 I.euryiinU. LoCKixGTox, I'loc. U. S. N.at. Mus., 1879, 326. 



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

 Head large; snout broad and long ; interorbital space very narrow ; month large, horizontal; 

 teeth conical, those of the npi)er 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 ou vomer or palatines. 

 Ventral fins very small; vertical fins continuous, without spines. {Collett.) 



This genus is represented by one or two species from moderately deep water oft" tlie 

 coast of California, Oregon, and Washington.

 Gt'iNTiiER, ChallonjicT Ri'iiort, xxii, 1887, 81. 



Body elongate, naked. Vertical flus without spines; ventral flus none. Small, conical 

 teeth on the jaws, vomer, and palatines. Grill-opeuings very narrow. No air-bladder; pylo- 

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

(iymnclis picliis, Gunther, Cat. Fish. ISiit. Mus., iv, 1862, 324. 



Height of body one-half the length of the head, which is contained about Ci times iii 

 the total length; 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. 



I'ectoral rounded, inserted low, its length less than half that of the head. Dorsal com- 

 mencing over posterior third of pectorals. 



Radial formula: 1). 100; A. 80. 



Color, brownish, usually with dark tran.sverse markings, but sometimes unspotted. 



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



MELANOSTIGMA, Gunther. 



Mclanostigma, Gunther, Proc. Zool. Soc. London. 1881, 20; Cliallengor Roport, xxii, 1877, 82. 



This genus agrees with Gi/mucllx and Miujuea in the absence of ventral fins, and tech- 

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

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

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