14 ON NEW GENERA AND SPECIES OF FISHES 
CARANGID &. 
TRACHINOTUS VELOX sp. nov. 
D. yi, 1 25; A. ii, 1 26; Sc. 100 cire. Depth ati bady 
22, length of head 3% in the length of the body. Dorsal 
profile a little more arched than the ventral ; profile of head 
slightly convex from behind the feebly declivous snout 
to the nape, thence obliquely linear to the origin of the 
dorsal fin. Snout as long as the diameter of the eye, which 
is 34 in the length of the head ; interorbital width rather 
more than the diameter of the eye. Jaws equal; maxillary 
reaching to below the anterior border of the pupil, its 
width at the distal extremity $ of the eye. Jaws with a 
narrow band of villiform teeth, the outer series slightly 
enlarged ; vomer with a triangular patch, palatines each 
with a short band of similar teeth. Cheeks and upper 
third of opercles scaly ; anterior half of lateral line undu- 
lating and slightly descending: posterior half straight. 
Anterior rays of the dorsal fin extending to the tip of the 
last ray, of the anal fin to the base of the caudal, the former 
1£, the latter 12 in the length of the body : upper lobe of 
caudal fin considerably longer than the lower lobe and a 
little longer than the produced anal rays: pectoral fin 
just reaching to the vertical from the vent, 7 of the length 
of the head: ventral reaching $ of its distance from the 
vent, its length 3 of the head. Bluish gray above, silvery 
on the sides and below; a series of from five to seven 
more or less conspicuous bluish spots above but usually 
touching and anteriorly sometimes even encroaching upon 
the lateral line : elongate rays of the dorsal and anal, and 
the outer rays and tips of the caudal lobes dark leaden 
blue (velox, swift). 
Type in the collection of the Amateur Fishermen’s 
Association of Queensland ; Cat. No. 289. 
By previous writers on Australian zoology this very 
distinct species has been confounded with the Indian 
Trachinotus russellii, the confusion having doubtless arisen 
through the similarity of the color markings in the two 
species. The western fish may, however, be easily distin- 
guished by its deeper body (21 in the length); by the 
shortness of the dorsal and anal lobes, which do not extend 
to the end of their respective bases, and of which the dorsal
