D. xi/12; A. iii/11: P. 18; V. i/5 ; C. 17. 55 pierced scales on the 

 lateral line, of which Hve are beyond the hypnral joint. About 63 rows 

 of scales above the lateral line between its origin and the hypural joint, 

 of which the anterior ones are very irregular; 52 rows between the 

 posterior margin of the supraclavicle and the hypural joint. 10 scales 

 between the origin of the dorsal fin and the lateral line, and 20 more to 

 the ventral surface. 



Deptli before the ventrals 21 in the length to the hypural joint; 

 head 36 in the same. Breadth at the pectoral bases 2*5 in the depth. 

 Eye shorter than the snout, 1'7 in the interorbital space, and 3*9 in the 

 head. Interorbital width 21, and snout 3 in the head. Depth of the 

 caudal peduncle 1 -t iti it.s length, and 21 in the head. Sixth dorsal 

 spitie 29, second dorsal ray 2'4, and pectoral 15 in the head. 



Body broadly elliptical, compressed, the upper and lower profiles 

 almost equally arched. Head obtuse, almost as deep as long ; the snout 

 is very convex before the eyes, but thence the profile rises evenly to the 

 origin of the dorsal. Eye almost entirely in the anterior half of the 

 head, and well below the upper profile ; interorbital space convex. 

 Preorbital, snout, and lips naked, the rest of the head covered with 

 strongly ctenoid scales. Preorbital and preoperculum serrated ; two 

 weak opercular spines. Nostrils approximate, near the eye, with low 

 skinny margins. Maxillary scaly, just reaching the vertical of the 

 anterior orbital margin ; jaws equal. Teeth in a single row in each jaw ; 

 the horizontal and vertical portions of the median premaxillar}' teeth 

 subequal in length. An angular patch of minute teeth on the vomer, 

 and a very small patch on the anterior part of each palatine; a vei'v 

 broad patch on each pterygoid, and a broad curved patch on the antei^ioi' 

 part of the tongue. 



Body entirely covered with strongly ctenoid scales, which also extend 

 over the greater portion of all the rayed fins, and form sheaths at the 

 bases of the dorsal and anal spines. Lateral line followitig the curve of 

 the back. Post-temporal bone seri-ated. 



Dorsal commencing a little behind the vertical of the ventral spine: 

 the margin of the spinous portion is evenly arched, and the sixth spine 

 is longest and much longer than the anterior rays. Soft doisal much 

 shorter than the spinous portion ; its margin is almost straight, and the 

 rays decrease in length backward. Anal a little farther back than the 

 soft dorsal; the second and thiid spines are subequal, and the anterior 

 i-ays are distinctly higher than those of the dorsal. Pectoral short and 

 broad, the fifth ray longest, the margin rounded. Ventrals reaching 

 about two-thirds of their distance from the vent. Caudal dee[)ly 

 emargiuate, the lobes pointed. 



Colour. — Dark silver, with longitudinal stripes extending along the 

 sides between each row of scales. Head silver and bionze ; a bi-onze 

 stripe across the eye and another across the cheek, between which is a 

 brilliant silver area. Opercular margin blackish. First doisal olive- 

 black, the other vertical fins lighter though dark towards their margins. 

 A blackish spot beneath the pectoral at the lower angle of its base.
