Bab. Ceylon, in slow-running streams on the northern side of

 south of the island, near the village of Heneratgodde. 



Possibly a variety of P. chilinoides, from which it " only differs 

 in wanting the depression round the upper part of the \vhorls 

 and in the colouring." It is found in the same localities as that 

 species.
