In the very young the upper jaw is very short, as in the tropical HemirampJius, 

 but gradually increases with age until it becomes almost as long as the mandible.

Length of head 3j to 4, of caudal fin 7|, height of body 15 to 16 in the total 

 length. Eyes large, 2j to 2f diameters in the length of the postorbital portion 

 of the head, 6| to 7 diameters from the end of the upper jaw, and 1 ^ diameters apart. 

 Upper surface of head not grooved : some slight grooves about the superciliary 

 region. Maxillaries concealed by the preorbital. Upper jaw not so long as the lower, 

 which latter has a soft termination. Teeth small, in some examples a small oval 

 patch is present on the vomer, in others it is absent. Fins the anterior dorsal 

 rays are elevated forming a lobe, while the posterior ones are of about the same 

 length and terminate opposite the anal ones, which is some distance from the base 

 of the caudal fin. Pectoral, if turned forward, does not reach the eye. Ventral 

 situated nearly midway between the opercle and the base of the caudal fin. 

 Caudal forked, lower lobe the longer. The free portion of the tail compressed, 

 nearly twice as long as high, and deeper than broad. Colours of a sea-green or 

 bluish-green along the back, becoming of a changeable blue and purple along the 

 sides, and silvery white beneath.
