Type locality : — East Indies. 
Depth of body 1-9 to 2 in its Length; dorsal eontonr rather more elevated 
than the ventral, its anterior profile linear and strongly acclivous to above the 
middle of the eye, thence by a moderate convexity to about the 5th dorsal spine, 
beyond which it descends in a long gentle curve to tlie middle of the soft dorsal, 
whence it bends more abruptly downwards to the caudal peduncle; ventral 
contour feebly convex between the chin and the wmtrals. thence linear to the 
anal, the base of which is evenly (*onvex ; least d(‘pth of peduncle b-75 in the 
length of the Imdy. Width of luaul l-b in its leiigth, which is M5 to 1-8 in its 
depth and 8-7 to 8-85 in the body-length. Diameter of eye 1*15 in the length of 
the snout, which is 2*7 in that of tlu' head; intcu’oi'lutal la^gion as wide as and 
one sixth less high than the eye-diamet(u\ .Maxilh-nw (xlimding to below the 
anterior nostril. Preorl)ital coarsely denticulated, its width 1-2 in the eye- 
diameter. Hinder limb and j^osterior half of lower limb ol* i)recpercle strongly 
serrated, the former inclined somewhat ])ackwards; spine long and curved, 1-75 
in the length of the head, and extending to beyond the middle of the pectoral 
])ase; subopercle serrated. 
Scales ctenoid, the exposed portion coarsely and horizontally striated, 
the stria^ smooth, each termhiating in a stout spinule, the l)asal portion with the 
margin conspicuously lobulate; in 51) series above the lateral line and (>,1/18 or 
19 betw^een the spinous dorsal and the vent. Scattered squamuUe ]^resent. 
Lateral line incomplete, terminating near the base of tin* last dorsal ray, the 
tubes simple. 
Dorsal fin originating above tlie operele, with xv lb rays, the soft portiioi 
2-6 in the length of the spinous; spines graduated, the 1st well developed, 1-75 
in the last, which is 1-8 in the longest ray and b-l to b*88 in the body-length; 
procumbent spine present; soft dorsal with acutely ])ointed outline, the 8th and 
9th rays longest, extending to beyond the levi'l of the middh* of the caudal, its 
hinder border feebly concave. Chuidal fin rounded, tin* midtile rays longer than 
the outer and -L-l in the length of the body. Anal fin with iii 18 rays, originating 
below the 10th dorsal spine, the 1st spine 1*88 in the last, which is 1*8 in the 
longest I’ay and b-25 to 6-5 in the body-kmgth ; soft anal similar in height and 
shape to but much longer than the soft dorsal. Pectoral with lb or 17 rays, its 
length 3-9 to 4 in that of the body; nth ray long(^st, extending to below the 7th 
dorsal spine. Ventral much longer than the pectoral, the spim* l-b in the outer 
ray, which is well produced, 8-85 in the ]>ody-length, and reaches beyond the base 
of the 1st anal spine. 
Gill-rakers 8-|-l^, short and pointed, except the anterior pair on the 
upieer branch, which are rudimentary. 
Posterior half of trunk and tail deep blue-black, the color continuous on 
the soft dorsal and anal and on the interspinous membrane of the anal and the
