as in Q. viridis, from which it may not be distinct; but the above charac- 

 ters appear in our specimens (from near the Pribilof Islands) and in Rich- 

 ardson's figure of G. utiimaculafus. The white spots on the head were 

 mistaken for "very small scales" in the original description of G. stigma 

 from Dr. Collie's notes. This description is, in substance, as follows : No 

 trace of ventral fins; dorsal, caudal, and anal fins united into a trans- 

 parent ridge; rays of branchial covering distinct; scales very small. 

 Color dilute brown, with void swathes and spots; a purplish spot near 

 beginning of dorsal fin. Snout obtuse; chin with a large gibbosity; 

 teeth small. Length about 5 inches. (Lay & Bennett.) Arctic regions, 

 Greenland to Bering Sea, with the preceding, and apparently equally 

 common. {6riy/ja, spot.)

943. LYCOCARA, Gill. 



Uronectes, Gunther, Cat., iv, 325, 1862 (parrii) ; name preoccupied in Crustacea. 

 Lycocara, Gill, Proc. Ac. Nat. Sci. Phila. 1884, 180 (parrii). 



Body ensiform, compressed; tail long and tapering; ventrals none; vent 

 not far distant from the head; numerous minute teeth in jaws and on 

 palate ; lower jaw the longer ; 110 barbel ; scales and gill openings unknown . 

 One species, very imperfectly known, no specimens having been obtained 

 by any recent collector. {Xvho^, "wolf; xapa, head.) 



2842. LYCOCARA PARRII (Ross). 



Head 4. D. 50; A. 45; P. 37. Head very obtuse, its length, depth, and 

 breadth equal ; head broader than the body, flattened and grooved be- 

 tween the eyes, which are lateral and rather large; lower jaw the longer; 

 jaws and palate with minute teeth; greatest depth of body somewhat 

 more than length of head; neck much arched. Dorsal inserted just 

 behind head ; pectoral extending beyond vent. Vent not far distant from 

 head. Color uniform. Baffius Bay. (Giinther.) (Named for Capt. William 

 Edward Parry, the Arctic explorer.)

944. MELANOSTIGMA, Gunther. 



Melan ostium a, Gunther, Proc. Zool. Soc. Lend. 1881, 21 (gelatinosum). 



This genus is distinguished from Bothrocara by the much more elongate 

 teeth, which in the jaws, as well as on the vomer and palatines, stand in 

 single series. Gill openings much smaller than in related forms, reduced 

 to a small foramen above the base of the pectoral. Skin loose and mov- 

 able, as in Liparis, enveloping the vertical fins; pectorals very small;
