the least depth of the caudal peduncle 10 % ; the length of the maxillary 257 % ; the 

 length of the pectoral fin 17 % ; the length of the ventral fin 94 % ; the length of the 

 base of the anal fin 38-5 %; the diameter of the eye 5 % and the length of the snout 

 is 3 '5 % of the total length. 



The snout is prominent, the maxilla is dilated above the mandibulary joint and 

 its posterior tapering portion extends further than the anterior root of the pectoral fin. 



The dorsal fin with its two spines and ten rays has an isolated scaly spine ante- 

 rior to it; there are twenty-five flat scales in front of the dorsal fin, the height of the 

 fin is J 7 % of the total length ; the origin of the fin is nearer to the end of the snout 

 than to the base of the caudal fin. 



The pectoral fin with fourteen rays has a broad appendage attached to the inner 

 side of the root of the fin and is about half its length when it lies flat against the 

 body ; the pectoral fin does not reach the root of the ventral fin, and is slightly shorter 

 than the length of the head.

The ventral fin with its eight rays has also an appendage in its axil which is 

 three-fourths of the length of the fin; the root of the ventral fin is nearer to the 

 origin of the anal fin than the mandibulary joint in the proportion of six to seven. 



The anal opening is nearer to the base of the caudal fin than the end of the 

 snout in the proportion of seven to eight, and is not reached by the tips of the ventral 

 fins. 



The anal fin has forty- three rays with one or two short compact spines. It 

 commences below the posterior rays of the dorsal fin : the length of the base of the 

 fin is contained 2-f times in the total length (without caudal fin). 



The scales are thin but not readily deciduous ; the number of scales in the lateral 

 line is fifty and across the body in the line of its greatest breadth thirteen. The 

 colour of the body is silvery with the back slightly dark and the fins hyaline. 



This new species is closely related to E. purava (H.B.) and E. mystax (Bl. and 

 Sehn.) but in a good many particulars it differs from both. From E. purava (H.B.) 

 it differs in being broader — (the height in E. purava being about four whereas in the new
