IHcrolene, Goode & Bean, Bull. Mua. Comp. Zool., x, No. 5, 202, 1883 {intronigra). 



Brotulids with body moderately compressed ; head somewhat com- 

 pressed; mouth lj>rge; tip of maxillary much dilated; eye large, placed 

 close to dorsal profile. Head with supraorbital spines; several strong 

 spines on jireoijercle and 1 long spine at upper angle of opercle. Suout 

 short, not projecting beyond the upper jaw; jaws subequal. Teeth in 

 narrow villiform bands in each jaw, on head of vomer, and on palatines. 

 No barbel. Gill openings wide, membranes not united; gills 4; gilllaminse 

 of moderate length ; gill rakers rather long, not numerous; pseudobran- 

 chiic absent. Caudal not confluent with dorsal and anal, but without a 

 distinct peduncle. Dorsal and anal fins long; pectoral rays in 2 gronp.s, 

 several of the lower ones being separated and much produced; ventrals a 

 pair of bifid rays, close together on the isthmus. Branchiosteguls 8. Body 

 and head covered with small scales; lateral line close to base of dorsal 

 flu, apparently becoming obsolete on posterior third of body. Stouiach 

 siphonal; pyloric c:eca few and rudimentary; intestine shorter than body. 

 Deep sea; a single species known. (Sijr/adoj, forked; coXevrj, \imh.) 



2893. DICROLENE INTRONIGRA, Goode & Bean. 



Head 5; eye large, 4 in head; interorbital width 4. D. 100; A. about 

 85; C. 6or 7; V. 1; P. 19 + 7 or 8; scales 110 to 120. Body moderately 

 compressed, its dorsal and ventral outlines approaching at an equal angle 

 the horizontal axis, and tapering to a narrow point. Head somewhat com- 

 pressed, with flattish upper surface, which is encroached upon by the 

 upper margin of orbit; a strong spine at posterior upper margin of orbit, 

 pointing backward and upward; a long, sharp spine at upper angle of 

 opercle, its exposed portion 2 in eye; 3 equidistant spines on lower pos- 

 terior border of preopercle, much weaker than that on opercle. Large 

 muciferous cavities in bones of head; a row of large cavities extending 

 backward from upjier angle of oibit, and continuous with those on lateral 

 line. Mouth large, its cleft considerably more than 4 head, the maxillary 

 extending beyond eye and with scales upon its expanded tip. Distance 

 from snout to origin of dorsal fin 5 total length; anal inserted under 

 twenty-fifth or twenty-sixth dorsal ray ; height of dorsal and anal fins each 

 about equal to eye ; length of caudal fin 2 in distance from snout to dorsal ; 

 ventrals about equal to upper jaw; pectorals inserted close to branchial 

 aperture, the 8 lower rays free and much prolonged, the longest and most 

 anterior being about 3 in body, and more than 3 times as long as the con- 

 tiguous posterior ray of the normally constructed portion of the tin, 

 which is, however, about equal to the last free rays. West Indies, Gulf of
