species it is only 3f ) , and in having a slightly shorter head and larger eye. In E. purava 

 the origin of the dorsal fin is midway between the snout and the base of the caudal 

 fin or a little nearer to the base of the caudal, but in the new species the origin of 

 the dorsal fin is nearer to the snout than the root of the caudal fin. The maxillary 

 is slightly longer in the new species than it is in E. purava. From E. mystax (Bl. and 

 Sehn.) the new species differs in having a shorter anal fin, a shorter head, a more promi- 

 nent snout and in having the origin of the dorsal fin nearer to the snout than to the 

 caudal fin. In E. mystax the pectoral fin when laid against the body reaches the root 

 of the ventral fin, whereas in the new species there is some distance between the tip of 

 the pectoral fin and the root of the ventral fin. In E. mystax the root of the ventral 

 fin is midway between the mandibulary joint and the anterior root of the anal fin, but 

 in the new species it is nearer to the anterior root of the anal fin. The new species 

 resembles Engraulis spinifer, Cuv. et Val., in having the origin of the dorsal fin nearer 

 to the end of the snout than to the base of the caudal fin, but it differs from it in 

 possessing a larger number of scutes, a longer maxillary and in many other important 

 particulars. It resembles E. valenciennesi (Blkr.) in having a longer anal fin and in 

 having the origin of that fin a little before the end of the dorsal fin and also in the 

 maxillary reaching slightly beyond the anterior root of the pectoral fin, but differs 

 from it in not having the dorsal profile convex and in not having the origin of the 

 dorsal fin nearer to the base of the caudal than to the snout, in having the pectoral 

 fins not reaching the root of the ventrals and in having a larger number of scutes. 

 Type.— A specimen 140 mm. long dredged in shallow water on i8-ix-i4 off 

 Nalbano Island. It is numbered F 11 ^ 1 in the Indian Museum register. 



Engraulis kempi, sp. nov. 

 (Text-figure 4.) 



The dorsal profile is almost straight as far as the dorsal fin, behind which it is 

 convex; the ventral profile is convex to the anal opening, posterior to which it is 

 somewhat concave. The body is compressed, and the shape is lanceolate. The ante- 

 rior abdominal edge is provided with twenty-three scutes beginning from the throat, 

 eight of these scutes are post- ventral. 



The height of the body is 28 % of the total length, the length of the head 20-5 %, 

 the least depth of the caudal peduncle 10%, the length of the maxillary 20-5 %, the 

 length of the pectoral fin 19 %, the length of the ventral fin 10 %, the length of the 

 base of the anal fin 32 %, the diameter of the eye 6 % and the length of the snout 5 % 

 in the total length without the caudal fin. 



The snout is prominent with a rostro-frontal projection which is rounded. The 

 maxillary is dilated above the mandibulary joint and its posterior tapering portion 

 does not extend beyond the gill-opening. 



The dorsal firfhas two spines and ten rays with an isolated spine' in front and 

 twenty flat scales. The point of origin of the fin is slightly nearer to the snout than 

 to the root of the caudal and its height is 19 % of the total length.
