2836. LYCODOMJS MIBABILIS, Goode & Bean. 



Head 7 in total length j depth about 18. D. about 80; A. about 70; C. 9; 

 P. 18 ; V. 3 ; scales as in Lycodes, the scales not extending out upon the fins ; 

 no scales on head and nape. Lateral line apparently obsolete posteriorly ; 

 not extending back of the extremity of the pectoral, its position median ; 

 eye high up, 2 in head, equal to postorbital portion of the head ; the width 

 of interorbital space less than diameter of pupil, 3 times in long diameter 

 of eye ; nostrils immediately in front of eye ; maxillary extending to verti- 

 cal through anterior margin of pupil ; mandible, to a little behind vertical 

 through posterior margin of the pupil; dorsal fin inserted slightly behind 

 vertical through base of pectoral (the portion of the fin present in the 

 mutilated specimen before us contains 80 articulated rays; the first 10 or 

 11 scutes do not support rays, but whether rays were originally present 

 or not can not be ascertained) ; longest dorsal ray about equal to longest 

 anal ray, its length about 3 in head; distance of vent from snout twice 

 length of head; anal beginning immediately behind vent, of about 70 

 articulated rays ; caudal rays extending beyond tips of ultimate dorsal and 

 anal rays, about 9 in number; distance of ventral from snout equal to 

 twice length of upper jaw; middle ventral ray longest, it being ^ as long 

 as postorbital part of head; length of pectoral equaling 3 times that of 

 snout. Off the New England coast, in depths of 721 to 1,309 fathoms; a 

 most remarkable little fish, (mirdbilis, wonderful.)

940. LYCONEMA, Gilbert. 

 Lyconema. GILBERT, Kept. U. S. Fish Comm. 1893 (1896), 471 (barbatum). 



Generic characters as in Ly codes, but the lower jaw covered with a dense 

 mass of slender filaments or barbels, between which can be seen the 

 mucous pores of the mandible. In Iluoccctes, a related genus from the 

 Antarctic, the mandible is provided with a series of hollow tubes, which 

 are doubtless the produced margins of the pores. Alaska. (Xvnos, wolf; 

 rijfj.a, thread.) 



2837. LYCOXEMA BARBATUM, Gilbert. 



Head 6; depth 11|; maxillary 3 in head; eye 3; snout 4|. D. 103; A. 

 90 (each counted to middle of caudal) ; P. 15, its length !-&- in head; ven- 

 trals very short, i to f diameter of orbit. A dense fringe of filaments 

 covers the entire under surface of lower jaw, extending to behind angle of 

 mouth ; another series laterally on the throat, and a few scattering ones 

 sometimes present on the brauchiostegal membranes; upper jaw without 

 barbels. Body slender; upper jaw overlapping the lower; mouth small, 

 maxillary reaching vertical from front of pupil ; teeth all conical, none 

 of them much enlarged, those in lower jaw in a patch or irregular 

 double series, narrowing to a single series laterally ; in upper jaw, a single 

 series, the teeth of which increase in size toward the middle line, the mid-
