TIGER PIMELODUS. 179 



distinct. It is destitute of scales; has a spinous 

 process on the body, near the opercle, which the 

 serrated spiny ray of the pectoral fin strikes against. 

 Lateral line straight, from the opercle to the middle 

 of the tail ; the ventral fin about the middle of the 

 fish. Tongue fleshy, upper jaw produced, teeth 

 fine and thickly set in both jaws ; intestines making 

 several flexures ; vent situate near the ventral fin. 

 Air-bag single, heart-shaped. This fish lives half 

 an hour after being taken from the water; it is 

 caught by the hook, baited with a piece of flesh or 

 other fish, and is sometimes also shot with the 

 arrow. They are not found below the falls, and 

 therefore few except Indians enjoy this delicious 

 fish. The length of the specimen was two feet 

 three inches."
