compressed, metatarsal tubercles. The hind limb being carried

 Male with two external subgular vocal sacs.

Closely allied to P. Tcroyeri, from which it difiers in the following 

 characters: — The distance between the tarsal and the inner meta- 

 tarsal tubercles is less than that between the two metatarsal tuber- 

 cles. Dorsal folds nearly straight. Sides of the snout with a white 

 line between two blackish ones, as in Leptodactylus mystacinw.
