and the root of the caudal. The height of the body is much less 

 than the length of the head, which is two-ninths of the total (with- 

 out caudal). The free portion of the tail is rather deeper than long. 

 Snout somewhat pointed, of moderate length, a little shorter than 

 the postorbital portion of the head. Eyes small. Upper margin of 

 the dorsal fin straight, oblique. Body with about eight dark cross 

 bands, finely edged with black ; they are angularly bent, the angles 

 pointing backwards. A black spot at the root of the caudal ; three 

 black bars across each caudal lobe.

 Caudal fin slightly emarginatc. Origin of the dorsal fin nearly 

 midway between the end of the snout and the root of the caudal. 

 The height of the body is somew hat less than the length of the 

 head, which is one-fifth of the total (without caudal). Snout of 

 moderate length, obtuse, a little shorter than the postorbital portion 

 of the head. Eye small. Length of the pectoral more than one- 

 half of the distance of its base from the ventral. Upper margin of 

 the dorsal fin straight, nearly horizontal. Body with about fifteen 

 rather irregular blackish cross bands ; a black band across the root 

 of the caudal. (Heck.)

A comparison of this species with the figure of C. tigris does not 

 show any essential difference, except that the Indian species is pro- 

 vided with a dark spot below the eye.

 The length of the head is one-seventh of the total (with the 

 caudal), the height of the body one-eleventh. Scales well developed. 

 The diameter of the eye is nearly one-fourth of the length of the 

 head. Base of the dorsal fin midway between the snout and the 

 posterior extremity o£ the caudal fin. Caudal slightly lobed at its 

 posterior extremity. Reddish brown, with very narrow light- 

 reddish vertical bands*, most distinct in the posterior part of the 

 body, where there are sixteen posterior to the commencement of the 



* The author has probably confounded the ornamental with the ground- 

 colour.
