This specimen agrees very well with Day's description (Fishes of India, 

 p. 519) except that, in our specimen, the anal fin is inserted opposite the end of 

 the first third of the dorsal. Day says that it commences below the last thii'd 

 of dorsal fin, but his figure (Plate 121, fig. 10) shows that it commences very 

 slightly in advance of the middle of the dorsal.
