Length of head 4f to 6, of caudal 5|, height of body 4f to 5 in the total length. Bye — ^with a broad 

 posterior and a moderately wide anterior adipose lid, the former covering two-thirds of the width of the iris, 

 diameter of eye 2/7 of length of head, 3/4 of a diameter from end of snout, and If apart. The width of the 

 head equals 2/3 of its length. Interorbital space rather convex and equal to about half the length of the head. 

 Preorbital scaled, curved, not emarginate and very finely serrated at its outer extremity : the end of the 

 maxilla uncovered. The mandibles meet at an acute angle, are not notched, but end in a knob which is 

 received into a corresponding depression in the upper jaw. Uncovered space below the chin long, narrow, and 

 pointed. Upper lip rather thick, oblique, and forming part of the end of the snout : a deep transverse groove 

 before the vomer. Teeth — a few minute ones in the lower jaw. Fins- — dorsal spines weak, the fin commences 

 midway between the base of the caudal fin and end of snout, or slightly nearer to the latter, its first spine 

 strongest, equal to half the length of the head, but not quite so high- as the second dorsal, which latter is 

 emarginate superiorly and covered with fine scales, its base is nearly as long as its height. Pectoral situated 

 above the centre of the depth of the body, and nearly or quite as long as the head. Ventral arises on a vertical 

 line, midway between the bases of the pectoral and first dorsal fins. Anal rather higher than the second dorsal, 

 its anterior fourth is vertically before that fin, its base is nearly as long as its anterior portion is high, its lower 

 edge concave, third anal spine 1/3 the length of the head, and 1/4 longer than the second. Caudal lunated. 

 /ScaZes— cycloid, rounded posteriorly, many fine ones over soft dorsal, anal, and basal half of the caudal 

 fins. A long, pointed, axillary scale, one also at first dorsal and ventral, 22 rows between snout and base of 

 first dorsal fin, the first and second dorsals arise above the twelfth and twenty-fifth scales of the lateral-line. 

 Pree portion of the tail in its least depth equals half the length of the head. Colours — grayish along the back, 

 silvery in the lower two-thirds of the body, sides of the head golden : tips of both dorsals blackish : extremity 

 of caudal gray : a dark spot at the upper edge of the base of the pectoral. 



Habitat. — Seas of India to the Malay Archipelago. The specimen figured (life-size) is from 

 Bombay.
