scarcely as broad as the head across the eyes, broader than long, 

 the widest part a little in front of the middle, obliquely narrowed 

 in front, much narrowed behind, with tw^o longitudinal ridges on 

 the disk, which meet in the middle and at the front margin ; the 

 sides finely crenulate ; strongly and closely punctured, which gives 

 it a dull appearance as compared with the elytra. Elytra at the 

 base broader than the thorax, and about three times as long, con- 

 siderably broader near the middle, and then narrowed towards the 

 apex, which is about as broad as the base ; strongly punctate- 

 striate, the surface rather undulating ; there is a strong transverse 

 impression on the disk near the middle. Legs rather long and 

 slender; tibiae pitchy. Length 2| millims.

Geographical Distribution of Indian Freshwater Fishes. — 

 Part III. Conclusion. By Feancis Dat, Esq., F.L.S. &c. 



[Eead December 5, 1878.] 



In the pages of the J ournal of this Society I have given an analysis 

 of the distribution of the A canthopterygian^ and Siluroid^ fresh- 

 water fishes of India, Ceylon, and Burma ; and I now propose 

 completing my inquiry by examining into what obtains in the 

 families Scombeesocid^, Ctprinodontid^, Cypetnid^, Noto- 



PTEEID^, and SYMBEANCHIDiE. 



Family Scombeesocid^. 



One freshwater form is found amongst the Indian genera. 



1. Belone^, Cuvier. Troj)ical and temperate seas ; some spe- 

 cies inhabiting fresh waters. 



Grenus Belone.
