1120 Catalogue of Malay mi Fishes. [Nov. 



The length of the head is 3|- in the total, measured to the centre of 

 the posterior margin of the caudal ; the depth at occiput is a little 

 less than the length of the head. The diameter of the eye is ^ of the 

 length of the head. The forehead between the eyes is arched, not 

 trenchant. The angle of the mouth is opposite the posterior margin 

 of the orbit. The card-like teeth of the jaws, vomer and palatals are 

 rather large, recurvous ; those of the tongue velvety. The greatest 

 vertical diameter of the body, in front of the first dorsal, slightly 

 exceeds the length of the head. No immoveable spine is perceptible 

 in front of the first dorsal fin. The anterior third of the lateral line is 

 a little arched, the rest nearly straight. The first dorsal is small : its 

 height but ^ of the greatest vertical diameter of the body ; the point 

 of the second dorsal is more than double the height of the former. The 

 length of the ventrals equals that of the head ; the anterior half of the 

 fifth ray is connected to the abdomen by a membrane. The length of 

 the pectorals is \ of that of the body, the caudal not included. The 

 caudal lobes are f of that distance. Single individuals occur rarely 

 at Pinang. This species greatly resembles Seriola nigrofasciatus 

 (Riippell,)* from which it, however, may at once be distinguished by 

 the remarkably shorter distance between the first and second dorsal.

Differs from Seriola in having one or two long arched teeth on each 

 side of the symphysis of the upper jaw ; in having a single series of 

 fine teeth in the lower, and on the symphysis one or two longer ones ; 

 and in the absence of free spines in front of the anal fin.
