46 DEEP SEA FISHES. 
the caudal, as broad as high, anteriorly wider than deep. Snout rather 
large, as long as the orbit, broad and somewhat truncate when viewed from 
above, acute as seen from the side, the extremity being the lower jaw 
extended forward of the upper. Mouth protractile, of medium width ; cleft 
rising forward ; maxillary nearly reaching a vertical from the hind border 
of the orbit, obliquely rounded on the end, three fourths as wide as the eye, 
bent downward behind the intermaxillary. Teeth small, in comparatively 
wide villiform bands on the jaws, in narrower ones on the palatines, and in 
a V-shaped group on the vomer. Tongue long, narrow, pointed, toothless. 
Kye large, prominent, hardly as long as the snout, less than one fourth of 
the length of the head. Nostrils small, widely separated ; anterior tubular, 
at the lip; posterior immediately forward of the orbit. Interorbital space 
convex, width equal to two thirds of the orbital length. Operculum with 
three somewhat hidden and drooping spines, median strongest. Preopercle 
curved and finely serrated along the middle of its hind edge. Subopercle 
elongate, thin, flexible, extending back of the opercle in the long opercular 
flap. Flap rather wide, reaching above the base of the pectoral. Gill 
openings wide; membranes not united, free from the isthmus. Gill rakers 
slender, three plus nine, with four rudiments at each end of the series. 
Pseudobranchie well developed. Suprabranchial gland  subtriangular, 
grooved in the middle. 
Hinder extremities of the fins acute. Dorsal originating little backward 
of the axils of the pectorals, outline descending toward the end of the 
spinous portion, soft rays longer and increasing in length backward, longest 
ray filamentary, two thirds as long as the head, and reaching the base of 
the caudal. Anal origin below the fifth of the soft rays of the dorsal. 
Pectorals narrow, little longer than the ventrals. Ventrals small, close 
together, inserted below the bases of the pectorals. Caudal deep, lobes 
sharp, notch one third of the length of the fin, rounded. 
Scales small, ctenoid, longitudinally striate, covering body, head, bases of 
the fins, and, to a considerable extent, the fin rays; those of the flanks 
nearly twice as long as wide. Lateral line complete, rising to within four 
scales of the fifth dorsal spine, thence gradually descending till not quite 
reaching the middle of the caudal peduncle. Four pyloric ceca. Longest 
specimen seven and one fourth inches. 
Red in life; with a band of brown from each eye to the end of the snout, 
with a narrow white (or blue) band from the suborbital to the pectorals.
