SILURIDJB. 133 



this mark is very indistinct in Madras specimens, but exceedingly 

 dark in those from Burma. 



The only objection to uniting the Madras with the Assam and 

 Burmese form is that the former has P. 1/12-13, the latter P. 1/15. 

 The shoulder-spot is not so well marked, and the dorsal fin not so 

 developed in the Madras variety. This fish is closely allied to 

 C. bimaculatus, but has a larger eye, a narrow band of palatine 

 teeth, much longer pectoral fins and maxillary barbels. The Bur- 

 mese form (C. iwtatus) is more elongated. 



Udb. Madras, Assam, and Burma.
