MR. F. DAT ON THE GEOGRAPHICAL 



1 to South India and Malabar ; 1 to Java ; and 1 restricted to 

 Ceylon. 1 Scombresocid, common to India and beyond. 1 Cy- 

 prinodont, found also in Malabar. 19 Cyprinoids, 3 of which are 

 distributed through India and Malabar, 1 extending to Africa ; 6 

 to South India, 5 of which are also found in Malabar ; 1 to India, 

 excluding Malabar ; 2 to Malabar ; while 7 are restricted to 

 Ceylon. 



In short, the freshwater fish-fauna of Ceylon would show a very 

 slight connexion with Africa, and that only through the same 

 genera being distributed throughout India and Malabar ; but 

 certainly there exists a Malayan^ element, to which I shall refer 

 further on. 



The Malabar fish-fauna is intimately related to that of Ceylon 

 and (but to a decreased extent) with that of the southern portion 

 of the Coromandel coast, as some species extend their range as 

 far as the Kistna. The following Table will show the relation- 

 ship of the Ceylonese freshwater fish-fauna to that of the remainder 

 of the region on the continent of India, also how it agrees with 

 the Hindustan subregion or elsewhere. 



^ Wallace remarks of Ceylon that although it " generally agrees in its pro- 

 ductions with the southern part of India, yet it has several birds which are 

 allied to Malayan and not to Indian groups, and a fine butterfly of the genus 

 Hestia, as well as several genera of beetles, which are purely Malayan." 



2 Those genera which have marine as well as freshwater representatives are 

 printed in italics.
