152 MR. J. D. OGILBY ON FISHES [Mar. 19, 
dorsal profile, from the tip of the snout to the origin of the caudal 
fin, forms a graceful and gradual curve, which is more abrupt on the 
head than on the body; the ventral profile is flat from the isthmus 
to the origin of the anal fin, behind which there is a gentle ascent. 
The lower jaw projects slightly beyond the upper when the mouth is 
closed. The cleft of the mouth is very oblique ; the maxilla reaches 
to beneath the posterior edge of the pupil of the eye; it is exceed- 
ingly broad, being no less than three fifths of the diameter of the eye 
at its hinder margin, while the breadth of the preorbital bears a 
similar proportion to it. The nostril is provided with two openings, 
the posterior of which is situated on the anterior margin of the eye, 
on a line with the upper edge of the pupil, and is of moderate size 
and round, while the anterior, which is placed midway between the 
eye and the tip of the snout ona slightly lower level, is oval and very 
minute. The opercle is armed with three spines, of which the 
middle is much the longest, while the upper is so small as to be 
difficult of detection ; the vertical limb of the preopercle is finely 
serrated, and three or four of the teeth on the rounded angle are 
much larger and stronger than the others; the horizontal mb is 
entire. Jeeth—there are one or two small canines on the front of 
each ramus of either jaw, between which are patches of small teeth, 
separated by a naked space at the symphysis; behind the canines 
are small cardiform teeth in a double row anteriorly, but posteriorly 
in a single row, where, in the lower jaw, they are distinctly longer: 
the vomerine teeth form a triangular patch, the palatine a narrow 
band; the tongue is toothless. Jins—the dorsal fin commences 
above the base of the middle opercular spine ; the spinous portion is 
much lower than the soft, and its baseis about one tenth shorter ; 
the spines are slender, and the variation in length is very slight, the 
last being the longest, and two and three fourths in the length of the 
head; the intervening membrane is deeply notched, and is without 
a filiform appendage ; the soft portion increases gradually in length 
to the thirteenth ray, beyond which it descends rather abruptly ; the 
longest ray is one half longer than the last spine. The third anal 
spine is the longest, but little shorter than the last dorsal, while its 
rays are much longer than those of that fin’. The ventral spine is 
one third longer than that of the anal, and the second ray, which is 
the longest, reaches only to the vent, and is four fifths of the length 
of the head. The pectoral fin is elongate and pointed, reaching to 
opposite the origin of the anal,'and equal in length to the head. 
The caudal fin is deeply forked, with equally developed lobes, none 
of the rays of which are elongate ; its length is just one fourth of 
the total. Scales—of moderate size, finely ctenoid, and firmly 
adherent; the basal half at least of all the fins is scaly, and the 
entire head is covered with scales, smaller, especially on the snout, 
than those of the body. The Jateral line has a long, gentle curve 
parallel to the line of the back. Colows—head and anterior half of 
the body rose-coloured, with a narrow, pale blue line running from 
1 In our specimen the fourth and fifth (Bleeker’s longest, vide figure in Atl. 
Ichth. t. vii. pl. xi. fig. 1) rays are broken off close to the base.
