commences midway between the end of snout and the base of the caudal fin ; its 

 undivided rays are strong, and spinous, the last being strongly serrated along ahnost 

 the whole of its posterior edge, and its length equals |th of that of the body beneath 

 it. The pectoral rather longer than the head. The ventral commences on the vertical 

 below the last undivided dorsal ray, and reaches above half-way to the anal ; the 

 latter fin when laid flat almost extends to the base of the caudal, which is deeply 

 forked, its central rays being only equal to fth of the outer ones. The lateral line 

 descends to above the base of the ventral fin, from which it is divided by three and 

 half rows of scales. This fish is silvery-blue along the back, becoming white on the 

 sides and beneath ; some of the scales with dark marks along their bases. A black 

 band down the middle of the dorsal fin. Outer edges of caudal Kkewise black.
