ji^yes diameter 2|- in the length of the head, f of a diameter from the end of the snout, 



and rather more than 1 apart. Interorbital space flat or rather concave. Barbels — 

 absent. Teeth — rudimentary. Fi7is — dorsal commences between the hind edge of the 

 orbit and the end of the lower caudal lobe, anteriorly it is two-thirds as high as the body. 

 Ventrals commence midway between the hind edge of the eye and the base of the caudal 

 fin, reaching to the end of the base of the anal. Anal begins on a line below the 

 middle of the dorsal fin. Scales— 28 rows between the occiput and the base of the dorsal 

 fin. CoZoMrs— bluish, becoming silvery along the abdomen : pectoral nearly black with 

 the first ray white, and an oblique wide white band crossing from its outer edge to a little 

 in front of its base. In one specimen the ventral is black tipped : caudal grayish.

 and preceded at its base by a small forwardly-directed spine : anal short. Scales large, 

 no enlarged roiv at base of anal fin. Lateral-line complete and continued to opposite the 

 centre of the base of the caudal.

 serrated, caudal deeply forked, its lobes acutely pointed. A small horizontal spme in 

 front of the dorsal fin pointing forwards and scarcely protruding from beneath the skin. 

 Lateral-line— complete. CoZo;(rs— brilliant silvery with lilac and blue shades and a 

 tinge of olive-yellow on the back. Dorsal fin orange-scarlet superiorly bordered with
