igiy.] Fauna of the Chilka Lake : Fish. 499 



of the specimen, was about the time when the mother-fish spawned. The species is, 

 however, very common in the brackish and fresh waters of Orissa and individuals 

 are often noticed even in nayan jhuris (road-side drains). This fish is proverbially 

 clever in eluding capture and special traps are constructed to secure it. It is not 

 improbable, therefore, that specimens in the lake escape capture. The presence of 

 the species after the freshets is, however, well established, as this individual was cap- 

 tured at a considerable distance from the mouth of any river. 



Distribution : — Estuaries and rivers of Bengal, Bihar and Orissa, United Provinces 

 and Burma, found far above tidal influence in fresh water.

There is only one specimen in the collection, 107 mm. in length. It was secured 

 at Satpara ; the time of capture is not stated. Probably the fish is only a casual visi- 

 tor to the outer channel. 



Distribution : — Seas of India ; coasts of Ceylon, Java, Sumatra and Borneo.
