Vomerine teeth villiform^ those in the middle of the band conical. 
The band of vomerine teeth is in its middle rather broader than 
that of the inter maxillaries ; it has a very short process in the 
middle of its concavity. Head rather finely granulated above^ its 
length being one-fonrth of the total. Barbels slender^ those of 
the nostril one-third as long as the head, those of the maxillary 
shorter than the head. The pectoral fin does not extend to the 
vertical from the origin of the dorsal ; its spine is short, not quite 
two-thirds as long as the fin. The dorsal does not extend on to 
the root of the caudal.

Vomerine teeth granular, forming a band, which in its middle is 
broader than that of the intermaxillaries ; it has not a process 
behind in the middle of its concavity. Head coarsely granulated 
above, its length being one-fourth of the total. Barbels long : 
those of the nostril extend nearly to the root of the pectoral, those 
of the maxillary beyond the origin of the dorsal. The pectoral fin 
extends to, or somewhat beyond, the vertical from the origin of the 
dorsal; its spine is short, not quite two-thirds as long as the fin. 
The dorsal extends to the root of the caudal.
