lateral line. The lateral line on both sides has a strong sinuous curve above the 

 pectoral fin. 



The fin-rays are weak and filiform : the dorsal begins in front of the eye, 

 on the snout. The caudal peduncle is strongly constricted, and expands again 



at the insertion of the fin, which is long and pointed, — 6- in the total length. 

 The pectorals are slender : that on the coloured side is much larger than its 

 fellow, its upper rays being nearly as long as the caudal. Both ventrals are well 

 developed. 



Colours : dull dusky brown, the peritoneum showing through as a black 

 patch ; iris and fins black ; tongue dusky brown.

The largest specimen is 8- inches long.

Cleft of the mouth very narrow : teeth in the jaws only, in broadish villi- 

 form bands on the blind side, gradually becoming obsolescent on the coloured 

 side. Byes on the right side, very large, almost in contact, the upper bulging 

 beyond the dorsal profile, the lower in advance of the upper. The dorsal fin 

 begins above the middle of the upper eye. Both pectorals and both ventrals 

 well developed. Scales of moderate size, stout ctenoid* and adherent on the 

 coloured side, thin cycloid and deciduous on the blind side. Lateral line with a 

 strong curve above the pectoral. 



Gill-openings somewhat contracted, the membranes very broadly united 

 below the isthmus : gill-rakers numerous, of good length, pointed. Six branchi- 

 ostegals. 



Closely allied to Pleuronedes.
