176 gangetic fishes. Order V. 



12th Species. — Pimelodus ram a. Plate III. Fig. 55. 



A Pimelodus with six tendrils shorter than the head ; with 

 the fin of the tail divided into two lobes ; and with a diapha- 

 nous body. 



This small fish, which I found in the Brahmaputra river, so 

 strongly resembles the Chandramara, already described, (page 

 162,) that I shall only mention those circumstances in which it 

 differs from the description of that species. 



The colour is yellowish, without dots. On the nape is a 

 large black spot, divided into four lobes. The six tendrils are 

 distinctly visible, and are thicker than the two which the 

 Chandramara has. In the fin behind the vent there are fifteen 

 rays. 



13th Species. — Pimelodus tengana. Plate XXXIX. Fig. 58. 



A Pimelodus with eight tendrils all shorter than the head ; 

 with the tail fin bifid ; with a diaphanous body dotted on the 

 upper parts ; and with fourteen rays in the fin behind the vent, 

 and eight in the foremost on the back. 



This is a pretty little fish, which grows to about three inches 

 in length, and is found in the Brahmaputra river. It is long 

 in proportion to its breadth, more prominent on the back 

 than below, and compressed on the sides ; and tapers gradu- 

 ally to both ends from the commencement of the first fin on 

 the back. The body is diaphanous, with a silver coloured 

 membrane investing the viscera and spine, and with a gloss of 

 gold on the sides. On the back are many black dots, which 

 are collected into a spot above each pectoral fin, and also on the 

 crown of the head. The fins of the back and tail also are dot- 

 ted, so that the edge of the last is black, and several spots are 

 formed on the first. 



The head is short, rather thick, oval, and a little sharp, with
