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 these 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. dirostratus it is dis- 
tinguished by a larger first dorsal, etc., from P. guiescens by a larger number 
of scales, by the postorbital groove, and the scaleless area in front of the 
dorsal, from P. albirostris by a straighter profile, and the postorbital groove, 
from P. xensma by the larger first dorsal, the naked space behind the 
occiput, and by absence of papille on the throat, and from P. gymnostethus 
by the squamation of the breast, ete.

Bror. 7; D: VIM, 18=195 A. 8195 V. 65 BP. 12 = 2 a as in: 
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 subopercular, as appears on 
P. crustosum. 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
