D. circ. 85. A. circ. 65. P. circ. 22. V. 2 (coherent at base). 

 Differs from N. macrops only in the following particulars : — 

 (1) Length of head about 3'- in the total. 



(4) Major diameter of the eye about one-sixth the length of the head. 

 (6) The bands of teeth in the jaws are not very broad. 

 (8) There are no spinules at the angle of the pre-operculum, which is 

 rounded. 



(13) The longest dorsal rays are about two-fifths of the greatest body height. 



(14) The distance between the first anal ray and the base of the pectoral 

 fin is equal to the length of the post-orbital portion of the head. 



(15) Pectorals rounded, their length not much more than half that of the 

 head.
