The humeral process is not always equally developed ; it varies 

 considei'ahly in its extent backwards, and is constantly less deve- 

 loped in immature examples. This species has, like its congeners, 

 the pharj'ngeal teeth in a triple series ; therefore Bleeker's division 

 " Chedri'^ is not only not founded in nature, but based on erroneous 

 characters. 



The spots on the scales are nearly constantly well marked, but the 

 bars across the back are visible in well-pi'cserved examples only. 



Opsarlus dualis, Jerdon, Madr. Journ. Lit. & Sc. xv. 1849, p. 330, 

 from Coimbatoor and Palghat, appears to be very closely allied to 

 the preceding species ; but it is said to be without barbels, and the 

 height of the body is contained thrice and two -thirds in its length.

Two barbels, nearly half as long as the head, inserted at the 

 upper end of the maxillary ; sometimes another pair of minute 

 barbels towards the lower end of the maxillary. The height of the 

 body is two-elevenths of the total length (without caudal), the 

 length of the head two-ninths or one-fifth. Moiith obliquely 

 descending backwards, rather wide, the maxillary extending nearly 

 to below the middle of the eye. Jaws equal in length, the lower 

 slightly projecting when the mouth is open. The diameter of the 

 eye is equal to, or rather more than, the length of the snout, less 

 than the width of the interorbital space, and two-sevenths of the 

 length of the head. The third suborbital bone is twice as wide as 

 the soft naked portion of the cheek. Dorsal fin higher than long, 

 its origin is midway between the eye and the root of the caudal ; 

 and its last two rays are above the front part of 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. Twelve blackish cross bars descend 

 from the back to the lateral line.
