The height of the body is 2-2^ in the total length, the leng-th of 

 the head 5-5|, one of the candal lobes 3|-4 times. The anterior 

 rays of the dorsal and anal more or less produced. Coloration uni- 

 form ; the dorsal, caudal, and anal lobes blackish or black. 



Atlantie coasts of tropical and temperate America, crossing the 

 ocean to the west coast of Africa ; Indian Ocean and Arcliipelago to 

 the coast of Australia. 



This species belongs to those Carangidce which inhabit the seas 

 of both hemispheres. The British Museimi possesses specimens from 

 the Atlantic and the Indian Oceans, in which not the slightest differ- 

 ence can be detected. The specimens differ in the length of the lobes 

 of the fins, and in the height of the body, chiefly according to their 

 age. Old specimens gradually lose the teeth*, and the anterior pro- 

 file of the snout is entii'cly vertical, whilst it inclines slightly back- 

 wards in immatru-e fish. I suppose that the other species of Tra- 

 ckpwtus undergo similar changes.
