Head and body much compressed and elevated, oblong, covered with 

 prickly skiu. Mouth wide, its cleft nearly vertical; teeth in jaws conic, 

 movable, of moderate size; no teeth on vomer or palatines. Gills 2; 

 gill arches unarmed. Spinous dorsal reduced to 2 spines, 1 on the head, 

 the other on the back, the basal element of the second spine exserted; the 

 cephalic spine much elongate; soft dorsal and anal short; pectorals very 

 short, broad, of about 20 rays. Caudal fin much produced, fan-shaped,

3109. CERATIAS HOLBOLLI, Kroyer. 



D. 1-1,4; A. 4; P. 19; C. 10. Head 2f ; depth nearly 2 ; head deeper 

 than long; eyes small, not more than -$ the length of the head; free rays 

 of the head a little shorter than to the base of the caudal fin ; the forked 

 part' of the caudal fin shorter than the length of the fish; the length 

 of the pectoral fin equals almost ^ - the entire length of the fish, the mem- 

 branes from the dorsal and anal fins posteriorly extend almost to the base 

 of the caudal fin. Color entirely black. (Kroyer.) North Atlantic ; 4 

 specimens known; 3 from Greenland, 1 from Nova Scotia. (Named for

General characters of Ceratias, but with the spinous dorsal reduced to 

 a single rostral spine, and 2 fleshy claviform tubercles or caruncles behind 

 it. Pectoral fins narrow, with 10 to 15 slender rays, (mancus, defective, 

 " with a quasi-diminutive termination to correspond with Ceratias.") 



a. Dorsal caruncles placed before dorsal fin a distance 6 times in length of trunk from 



gill opening to base of caudal. URANOSCOPUS, 3110. 



aa. Dorsal caruncles placed nearer dorsal, the distance from dorsal 4 J times in trunk, 



as above. SHUFELDTI, 3111. 



3110. MANCALIAS URANOSCOPUS (Murray). 



D. I, 3 or 4; A. 4; C. 8; P. 10. Anterior spine of first dorsal produced in 

 a long filament, ending in a pear-shaped bulb, terminating in a semitrans- 

 parent whitish spot, this spine originating on posterior part of head, and 

 reaching, when depressed, nearly to the tip of tail; far behind this are 2 

 short, fleshy tubercles, lying in a depression in front of second dorsal. 

 Teeth moderate, depressible. Skin everywhere with minute embedded 

 conical spines. Eye very small, placed high on the middle of the head.
