110 DEEP SEA FISHES. 



lateral line and with others from the line down and backward to the white 

 (red) of the lower portion of the entire body. A darkish spot below the eye 

 on the cheek. Lower ends of the oblique streaks on the flanks darker ; 

 upper portion, as also the basal parts, of the dorsals darker. Or tliese fins 

 may be described as similar to those of P. miles in having a lighter longi- 

 •tudinal area in the middle. Upper twelve rays of the pectorals darker, 

 lighter toward the ends. Caudal reddish with blackish upper edge and 

 with two transverse lunate bands of blackish. Ventrals white. 



This species is separated from P. miles by the postocular tubercles, the 

 shortness of head and body, and other features ; from P. birostratus it is dis- 

 tinguished by a larger first dorsal, etc., from P. quiescens by a larger number 

 of scales, by the postoibital groove, and the scaleless area in front of the 

 dorsal, from P. albirostris by a straighter profile, and the postorbital groove, 

 from P. a-euisma by the larger first dorsal, the naked space behind the 

 occiput, and by absence of papillae on the throat, and from P. g^mnosteihus 

 by the squamation of the breast, etc.

Br. r. 7; D. VIII, 18-19; A. 18-19; V. 6 ; P. 12 + 2 ; LI. 33; Ltr. 4. 



Body moderately elongate, depressed, slender behind the body cavity. 

 Head massive, tapering to narrow from the orbits, more than one third as 

 long as the distance from snout to end of caudal, twice as long as deep, 

 three fourths as wide as long ; width of crown equal to length of orbit or to 

 width across ends of rostral processes ; suborbital keel prominent from the 

 rostrum backward widest in a blunt angle opposite the hind border of the 

 eye; a less prominent keel on the suboperculum, sharper backward. No 

 smaller angle between the suborbital and the subopei'cular, as appears on 

 P. cnisiosum. A slight prominence on the suborbital keel opposite the for- 

 ward half of the eye. Snout depressed, broad, concave longitudinally, arched 

 transversely, more than half as long as the head ; rostral processes as long as 

 the orbit, separated at the mouth by about one third of the orbital length, 

 converging forward, depressed, blade-like, wider than the space between them, 

 denticulate on the edges, rounded and bearing several larger denticles on 

 the ends, top of each basal portion with a large backward inclined spine
