The species of the three jSTandioid genera found in India give the 

 following results : — Nandus is generally distributed except in Sind 

 and elevated regions, extending eastward at least to Siam. It is 

 a widely diffused fish. Badis shows species (perhaps the two are 

 varieties of one) extending from the plains on to moderately ele- 

 vated hills, and having a wide distribution to the east. Pristole- 

 pis is more confined to hilly regions or their bases in India pi'oper, 

 or, rather, Malabar ; and then a wide hiatus exists, as it has not 

 been discovered nearer than Burma, where it is found in the 

 plains. There is, however, a slight difference in tiiese fishes, Avhicli

 Cania, in Ceylon, and which may be one of those mentioned as found in India. 

 Anyhow it proves the existence of this genus in the fresh waters of Ceylon,
