Length of head i, of pectoral J, of caudal ?,-, of base of dorsal \, of base of anal \ of total 

 length. Height of head J, of body \, of dorsal -j 2 .,, of anal ^, of ventral T ' 3 of total length. 



Eyes — With wide adipose lids, having a circular orifice in the centre of each, diameter f of 

 length of head, f of a diameter from end of snout, and 1 diameter apart. 



Body elliptical, highest opposite the front of the dorsal fin. Sides rather compressed, abdo- 

 minal line ending in a sharp toothed keel. Profile from snout to dorsal gradually rising, from the 

 posterior end of the dorsal sinking as gradually to the caudal. The lower profile slightly convex. 



Mouth small, half wider than deep. Lower jaw the longest, with a tubercle at the symphysis. 

 Posterior extremity of the upper jaw reaches to opposite the centre of the orbit. The nearest 

 supplementary bone to the maxilla thick and rounded above, flattened expanded and sulcated 

 inferiorly : posterior bone narrow, and with a circular expansion inferiorly. Opercle two and a 

 quarter times as high as wide, its superior and inferior margins oblique, its anterior and posterior 

 ones straight, (in immature specimens there is a slight bulging at the centre of the pos- 

 terior margin) some oblique badly marked veinings on the opercle. Subopercle trapezoid, half 

 longer than it is high. Preopercle large, with the posterior border vertical and its angle rounded. 

 Subopercle small. Branchiostegous membrane wide. Interorbital space with a V-shaped elevation 

 in its centre, apex in front, and its base emarginate behind. Nostrils oval, large, and nearer to 

 the snout than to the anterior margin of the orbit. Abdomen sharp, keeled, and its margin 

 denticulated. 



Teeth — Very small in the lower jaw, and deciduous. There are some minute ones on the 

 palate, and also a small longitudinal band in the centre of the tongue. 



Fins — The distance from the snout to the anterior extremity of the dorsal fin, is equal to the 

 distance from the base of the caudal to the posterior extremity of the same fin : pectoral situated 

 just beneath the posterior inferior angle of the subopercle : ventral under the centre of the dorsal : 

 anal midway between the commencement of the ventral and the base of the caudal. Dorsal 

 highest in front, first five rays undivided, the fifth the highest, the last rays slightly prolonged : 

 upper margin concave ; at the base of the fin there is a double row of scales, forming a groove, 

 which at its posterior end almost conceals the whole of the last two rays. Pectoral pointed. 

 Ventral triangular, with an elongated scale at its base. Anal with the first three rays undivided, 

 the fin parallel with the abdominal surface. Caudal deeply lobed, the longest ray equal to the 

 length of the head, or even more. 



Scales — Vertical diameter the longest. 



Colours — Upper surface of head and back greenish, abdomen silvery shot with green and
