Habit. — Sea of Pinang, 



Coromandel, Gangetic estuaries, Java, Madura. 



Total length : 8 inch. 



The length of the head is £ of the total. The horizontal diameter 

 of the eye is contained A\ times in the length of the head, the distance 

 across the forehead is 1 \ diameter. The greatest vertical diameter, in 

 front of the dorsal slightly exceeds \ of the total length. The maxillaries 

 are narrower and longer than iu E. hamiltoni, where they reach to the 

 root of the first pectoral ray ; in the present species they reach to the 

 root of the posterior pectoral ray. The dorsal commences a little in 

 front of the centre between the muzzle and the root of the caudal ; 

 the anal commences in the centre of that space, opposite the middle 

 of the dorsal. The extent of the base of the anal is ^ of the total 

 length. The caudal lobes are equal, pointed, and as long as the head. 

 The pectorals are a little shorter. The ventrals are situated a little 

 nearer the pectorals than the anal. At Pinang this species appears to 

 be of uncommon occurrence.

Gape wide ; gill-opening very open ; muzzle projecting, supported by 

 the ethmoid bone ; upper maxillaries free, projecting beyond the opercle, 

 and in some species reaching the root of pectorals ; dorsal placed on 

 the anterior part of the back ; body elongated, compressed, tapering to 

 a pointed tail ; anal joining the caudal, elongated, low, but in one species 

 tail shortened and caudal widened, rounded ; above the pectoral two 

 groups of filaments, parting from a common base ; in general characters 

 like Engraulis (Thrissa), but the anterior pharyngeals are more dis- 

 tinctly, though minutely, toothed. 



* Zool. Misc. 9. — Mr. Gray's characters are: "Body tapering, compressed; 

 dorsal fin short, over the ventrals ; anal and caudal fin united ; pectoral fins small ; 

 rays five ; three upper long and free ; rest of the characters like Thrissa."
