INDIAN FRESII-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 PSILOEHYNCnUS. 
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.
