74 INDIAN FRESH-WATER FISHES. 



Chest and middle of abdomen scaleless; post pelvic 

 region covered with very large scales. 



This seems to agree pretty closely with the fish 

 described by Dr. Day under the name of Mayoa 

 modes ta. 



I have in my note-book a sketch of another species 

 of Discognathus with 44 scales, from the base of the 

 Khasia Hills. Dorsal rays 2+6. 



GENUS PSILOEHYNCHUS. 



The two fishes belonging to this genus are found 

 in the hill streams in N. E. Bengal and Assam. 

 The snout is very long, the mouth underneath. 

 Barbels none. 



1. Psilorhynchus sucatio. 3 inches. 



Char. Snout much longer than the rest of the head. 

 Sides clouded with dots. Colour above greenish, 

 below whitish and diaphanous, fins dotted. 



2. Psilorhynchus balitora. 2 inches. 



Colour reddish brown, with irregular black blotches, 

 disposed in longitudinal rows. Three bars on the 

 caudal fin. Body diaphanous.
