Type locality: — East Indies. 



This species was described from a single example in the Brussels museum 

 with no definite locality. It has since been taken three or four times in the 

 mountains of west Java. Bryant got one specimen on the slopes of Mt. Gede, 

 near Tjibodas, during August, 1909. This single individual agrees generally 

 with the original description. It does differ, however, in having an apparently 

 rather smaller tympanum, which is bordered above by a strong fold running 

 from the eye to the axil. So that it is possible that this specimen, which is an 

 adult female, may in reality represent a second species of this little-known genus ; 

 though without more material conjecture is futile. The type was a male, and 

 there may easily be some sexual dimorphism.

TTjpe locality: — Java. Incorrect, it has not been taken in the true 

 Malayan Islands. 



A single young individual evidently of this species was taken under a rotten 

 log in the woods near Ansus, Jobi Island, New Guinea. This specimen has no 

 light dorsal line as van Kampen has noted for some Papuan specimens, and 

 Boettger (Abh. Senck. nat. ges., 1901, 25, 2, p. 367) for Halmahera. Five speci- 

 mens have just been received from Goram Island, a new locality for the species. 



Now known from the Philippines, Ceram, Halmahera, Batanta, New 

 Guinea, Jobi, Misori Island, and the Bismarck and Solomon Islands. 



Cornufer corrugatus rubristriatus Barbour.

 Barbour, Proc. Biol. soc. Wash., 1908, 21, p. 190. 



Type locality: — Roon Island, Geelvink Bay, New Guinea. 



Two examples from this island seemed almost specifically distinct from true 

 C. corrugatus. They both lack the characteristic dermal fold which extends from 

 the eye to the shoulder. The tympana are round instead of vertically oval, 

 there are three palmar tubercles, and the tibiotarsal articulation reaches only to 

 the eye. The inner sides of the thighs are yellow, and down the brownish olive 

 back runs a brick-red vertebral stripe. 



In other characters there does not occur any such divergence. It seems
