The length of the head is as much as two-fifths of the total without the caudaL 



The maximum height — which is just in front of the pectoral fins — is one-fifth of 

 the length without the caudal. 



The vent is equidistant from the base of the caudal and the nearest point of the 

 opercular margin. The attachment of the ventrals is half-way between the vent and 

 the nearest point of the opercular margin. The diameter of the eye is a third of the 

 length of the head and is more than the length of the snout. The eyes are separated 

 by less than their diameter. The snout is 3f in the length of the head. The mouth 

 is nearly horizontal. The posterior end of the maxilla reaches nearly as far back as 

 a vertical through the centre of the eye. The upper jaw slightly overlaps the lower. 

 Teeth are conspicuous and occur on the premaxillae, dentaries, palatines and vomers. 

 The gill-cover is voluminous and widely open below ; it is covered like the rest of the 

 head with soft black skin. The gill-rakers are numerous, long, lanceolate and acute, 

 the pseudobranch is present but small. The scales are rather large, their length and 

 breadth are equal. 



The dorsal and anal fins are approximately of the same length and lie opposite 

 to one another. Stomach siphonal. There are seventeen pyloric caeca of moderate 

 length. 



Colour in spirits. — Head jet black, body brownish black, fins black with a bluish
