Length of specimens to 5| inches. 



Length of head nearly \, of pectoral a little above i, of base of 

 dorsal yS^, of base of anal above A, of caudal a little more than \ of 

 the total length. Height of head j^jj, of body above i, of dorsal fiu 

 nearly i, of anal nearly \ of the total length. 



Eyes. Orbits circular, their upper margin close to the profile. 

 Diameter not quite \ of length of head, 1 diameter apart posteriorly, 

 I anteriorly, and the same distance from the end of the snout. 



Profile rises to over the centre of the pectoral fin, whence it pro- 

 ceeds direct to the base of the caudal. Its abdominal profile is more 

 convex than its dorsal. Abdomen sharp, cutting anteriorly j body 

 and head compressed laterally. 



Cleft of mouth extending to beneath the anterior third of the 

 orbit ; the lower jaw is directed obliquely upwards, so that its ante- 

 rior extremity is nearly level with the dorsal profile. The lower jaw 

 has a knob at its symphysis, which is received into an emarginatiou 

 formed by the intermaxillary bones. Nostrils generic. Prseorbital 

 nearly oval, its superior and inferior margins being twice the length 

 of its anterior and posterior ones. 



Fins. Dorsal situated in the posterior third of the distance be- 

 tween the snout and the base of the caudal fin, and over the com- 

 mencement of the anal. Pectoral commencing under the posterior 

 extremity of the opercle, extends to rather beyond the base of the 

 ventral, which does not quite reach so far as the anal. Dorsal and 

 anal both highest anteriorly, with their external margins shghtly 

 concave, their first undivided rays minute. Pectoral and ventral 

 pointed, the outer ray of the first strong and undivided. Caudal 

 deeply lobed. 



Scales moderately large, and with six or eight well-marked lines 

 radiating from their bases towards their circumferences. A few scales 

 exist along the anterior portion of the base of the anal and caudal fins. 



Lateral line consisting of a single tube in each scale ; commencing 

 on a level with the upper margin of the opercle, it bends downwards 

 for about twelve scales, when it reaches above the base of the ventral 

 fin, from here it follows the curve of the abdomen to opposite the 

 lower third of the base of the caudal, when it suddenly ascends to 

 attain its centre. 



Teeth. Pharyngeal teeth curved, pointed at their extremities, and 

 in three rows, 5, 3, 2/2, 3, 5. 



Colours. Brilliant silvery, with a brownish-green back, divided 

 from the abdomen by a broad green band, which extends from be- 

 hind the upper part of the orbit to the centre of the caudal fin. 

 Fins yellowish ; external portions of dorsal and caudal stained with 

 dark, due to numerous minute black spots. Outer margin of anal 

 also darkish.
