INDIAN FRESII-WATER FISHES. 
Dr. Day, who appears to have examined specimens, 
says that it properly belongs to this genus. 
Hab. Bengal and Orissa. 8 inches or more. 
Char. Anal rays 39 to 43. Barbels not longer 
than the head. Dorsal spine nearly smooth. 
GENUS SCHILBICHTHYS. 
Char. This genus is nearly allied to Pseudeu- 
tropius. The points of difference seem to be, 
no adipose fin in the adult. Nostrils close together, 
very wide. Head covered with skin. 
1. Schilbichthys garna. 
Dr. Day remarks that the young of this species are 
provided with an adipose fin, which becomes al- 
together absorbed as the fish grows larger. 
Hab. Northern India. 
Char. Anal rays 29 to 36. 1 to 2 feet in length. 
The maxillary barbels extend as far as the ventral 
fins. Nasal barbels short. Dorsal and pectoral spines 
serrated interiorly. The amount of the serrature 
appears to vary. 
GENUS AILIA. 
Char. Dorsal fin absent. Adipose fin very small. 
Barbels eight, all of them long, the mandibular 
pairs being placed in one line. 
I. Ailia bengalensis. 
“ This small but well-flavoured fish is found 
throughout all the large rivers of India, excluding 
those of Madras and Bombay. It attains about 7 
inches in length.” Day. 
Char. Anal rays 70 to 72.
