Pimelodus. gangetic fishes. 203 



The upper lobe of the tail fin is by a little the longest and 

 sharpest. It has eighteen distinct rays, besides some compact- 

 ed ones. 



31st Species. — Pimelodus menoda. 



A Pimelodus with the fin of the tail divided into two nearly 

 equal lobes ; with eight tendrils, of which two reach to the end 

 of the first back fin, and four others beyond the head ; with a 

 smooth opaque body, of a dark colour above ; with thirteen 

 rays in the fin behind the vent, and with nine in that of the 

 back. 



This fish, which is found in the Kosi, Mahauanda, and other 

 rivers in the north of Behar and Bengal, has so strong a resem- 

 blance to the Gulio now described, that I need onlv mention 

 the few particulars in which they differ, and which may perhaps 

 be considered as insufficient to distinguish them as species, al- 

 though my people from the South would not allow the Menoda 

 to be the same with their Guli, and reckoned it a species of 

 Gagora, while the Gulio they class with the Tengara. 



The Menoda has a large black spot on the hinder fin of the 

 back. 



The head is still flatter than that of the Gulio. 



The prickle of the back is barbed only behind. 



There are five undivided, and only eight branched, rays in 

 the fin behind the vent. 



32d Species. — Pimelodus cavasius. Plate XI. Fig. 67. 



A Pimelodus with the fin of the tail divided into two unequal 

 sharp lobes ; with eight tendrils, of which two reach beyond the 

 tail ; with a smooth nearly opaque body, brownish above ; 

 with thirteen rays in the fin behind the vent ; and with eight 

 in the foremost of the back.
