Dorsal fin short, with less than nine branched rays, inserted 

 distinctly behind the root of the vcntrals. Anal fin elongate, with 

 ten or more rays. Mouth anterior. Barbels four, two or none. 

 The maxillary reaches to or below, but not behind the orbit. Sub- 

 orbitals generally broad, the third never being narrower than the 

 soft naked portion of the cheek, and partly situated below the orbit. 

 Gill-rakers very short ; pseudobranchia^. Pharyngeal teeth 5 . 3 or 

 4 . 2 or 1 — 1 or 2 . 4 or 3 . 5, uncinate.

Barbels none. The height of the body equals the length of the 

 head, and is one-fourth of the total (without caudal). The maxil- 

 lary extends beyond the vertical from the front margin of the orbit. 

 The third suborbital bone is more than twice as broad as the soft 

 naked part of the cheek. One or two irregular series of greenish 

 spots along each side of the body.

Our ki owiedge of Opsarius hrachialis, M'Cloll. Ind. Cypr. pp. 297, 

 418, tab. 48. fig. 6, considered by M'Clelland himself to be only a 

 variety of 0. tileo, rests on the miserable figure given in the paper 

 quoted. 



2. Barilius radiolatus. 

 D. 10. A. 12. L. lat. 58. L. transv. 10/6. 



A very small barbel at the upper end of the maxillary. The 

 height of the body is nearly equal to the length of "the head, which 

 is contained foiu" times and a half in the total (without caudal). 

 Mouth obliquely descending backwards, of moderate width, the 

 maxUlary extending somewhat beyond the front margin of the eye. 

 Jaws equal in length, the lower slightly projecting when the mouth 

 is open. The diameter of the eye is equal to the length of the 

 snout, rather less than the width of the interorbital space, and 

 two-sevenths of the length of the head. The third suborbital bone 

 is nearly contiguous with the praeopercular ridge. Dorsal fin higher 

 than long, its origin is midway between the eye and the root of the 

 caudal; and its last ray is before the vertical from the anal fin. 

 Caudal fin deeply forked. Pectoral not extending on to the ventral, 

 shorter than the head ; ventral reaching the vent. Pectoral process 

 of the humerus very short. Scales with numerous very distinct 

 radiating striaj. Silvery, back reddish.
