D. x 11 ; A. iii 11 ; P. 14 : Sc. 4/50/11. Depth of body 25, 
length of head 2*85, of caudal fin 3'15, of pectoral 4/25, of ventral 
4*25 in length of body. Depth of peduncle 2*75, length of snout 
3*75, diameter of eye 275, width of interorbit 3*(5, length of max- 
illary 2 - 6, longest dorsal spine 1*5, longest anal 2*3 in length of head. 
Body ovate, the dorsal and ventral contours about equally arched, 
,its depth one eighth more than the length of the head ; caudal 
peduncle slender, its length 1*35 time its depth, which is 3*1 in that 
of the body. Upper profile of head and nape rectilinear and moder- 
ately oblique, with a slight convexity in front of the dorsal ; snout 
short and rounded, 1*35 in the eye-diameter, and about equal to the 
flat interorbital width; lower jaw projecting ; maxillary extending 
to below the anterior border of the pupil, the width of its distal 
extremity 3*6(5 in the eye-diameter. Preorbital and preopercle feebly 
.serrulate; opercular spines strong, the lower the longer. Upper 
surface of head wholly naked ; cheeks and opercles with finely 
ciliated scales, in four series on the former. 
Dorsal originating behind the base of the pectoral, its outer 
border strongly arched ; first spine shortest, 1*4 in the ninth, which 
iis-1'6 in the last ; fourth longest, a little longer than the fifth and 
one fourth longer than the anterior ray ; last spine nearly as long 
as the third or sixth. Middle caudal rays 1*6 in the outer and as 
long as the head in front of the hinder margin of the eye, the lobes 
acutely pointed. Anal originating below the first dorsal ray, its 
distance from the caudal 17 in its length; second spine a little 
shorter than the third, which is rather less than the tenth dorsal and 
rather more than the anterior rays. Fourth pectoral ray longest, 
1*5 in the length of the head, and not extending to the vertical from 
the vent. Ventral as long as the pectora!, reaching to the anal. 
Grill-rakers 22, the longest half the eye-diameter and twice as 
-long as the gill-fringes.
