Clupanodon. gangetic fishes. 249 



5th Species. — Clupanodon cortius. 



A Clupanodon with fifteen rays in the fin of the back, and 

 twenty-four in that behind the vent ; and with no spot on the 

 shoulders. 



This fish, found in the Brahmaputra near Goyalpara, re- 

 sembles also the Manmina so strongly, that I considered it un- 

 necessary to mark any thing but the specific character. 



6th Species. — Clupanodon chanpole. Plate XVIII. Fig. 74. 

 A Clupanodon withg fteen rays on the fin of the back, and 

 twenty-one in that behind the vent ; with from three to six 

 black spots on each shoulder ; and with the ridge of the back 

 blunt or rounded. 



This fish is found in the ponds and ditches of every part of 

 Bengal, grows to about four inches in length, and is very little 

 valued. It is shaped like the wide head of a lance. Its colours 

 are green above, and silver below, with from three to six black 

 spots, extending in a line from each shoulder. The fins are 

 pellucid, and that of the tail is dotted. The eyes are silver. 



The head is oval, descending in the same gentle curve from 

 the back fin to the nose, blunt, and moderate sized. The 

 mouth is horizontal, opening a little below the end of the nose. 

 The jaws are nearly equal in length, and the bones, in place of 

 the upper Up, do not reach beyond the gap, are club-shaped, 

 and entire on the edges. The under jaw is veiled with a pro- 

 jecting membrane. The tongue is sharpish, undivided, smooth, 

 and fixed its whole length. The palate is smooth, with a con- 

 vexity on each side. The aperture of the nostril is circular, 

 and nearer the jaw than it is to the eye. The eyes are globu- 

 lar, with circular pupils. Each gill-cover consists of four 

 plates, and exposes its membrane, containing six rays. 



The scales are moderate in size, smooth, and adhere firmly. 

 On each side of the nape is a naked bony plate striated on the
