In Dr. Annandale's collection there is a half-grown specimen and two young ones 
of this species. The former was collected at Singgora, while the latter were obtain-

and B. Pak Cha. The species is known to ascend tidal rivers and its range extends 
from Red vSea through the seas of India to the Malay Archipelago and beyond.

There are altogether six specimens of this species in the collection, three were 
obtained at the mouth of the Patalung river, while the remaining were netted in small

members of which have not hitherto been found east of the Peninsular India. 
Pristolepis fascintus is found in fresh-waters of Burma, Siam and the Malay 
Archipelago.
