128 INDIAN FEESH- WATER FISHES. 



GENUS SILUKICHTHYS. 



Char. Similar to Silurus, from which it may be 

 recognised by its having 8, or less, rays in the ven- 

 tral fin. Canclal forked. Anal and candal fins confluent. 



1. Silurichthys lamghur. 



Hab. Cashmere. 



Char. Anal rays 53. Ventrals 6. Barbels 4. 



Lower jaw prominent. Pectoral spine serrated. 



GENUS WALL AGO. 



Char. Barbels 4 ; viz., one maxillary, and one 

 mandibular pair. 



ISTo adipose fin. Dorsal very short. Anal fin not 

 joining the caudal. 



1. Wallago attu. "TheBoalli." 



Hab. Throughout India. Attaining sometimes as 

 much as 6 feet in length, according to Ham. Buchanan. 



This is a remarkably good fish for eating purposes, 

 when taken from clean water, and is much in request 

 among the natives. In Sylhet they capture it by spear- 

 ing from a boat rowing slowly up stream and coming 

 behind the fish. This would seem to indicate that it 

 is not a bottom feeder like many of the Siluridse. Dr. 

 Day states, however, that it is not a cleanly feeder ; 

 and I can well imagine, being a most voracious fish, 

 that its taste and habits are readily adapted to circum- 

 stances. 



Char. Anal rays 86 to 93. Maxillary barbels 

 long, nearly twice the length of the head. Pectoral 

 spine feeble, not serrated exteriorly.
