in the Philippine Islands by endemic genera. Only a single, 
recently described genus, Hazelia, appears to be confined to the 
Archipelago. Fifteen genera, all that are known from the Is- 
lands, are found in Mindanao; five of these have been discovered 
also in Luzon, and ten in Palawan. The five genera known 
from Luzon also occur in Celebes and Borneo, and two of them 
occur in Japan; the latter, however, are the widely spread genera 
Rana and Polypedates.

* Very doubtful in the Philippine Islands. 
New Guinea has four genera in common with Mindanao, three 
of which are also common to Borneo. Celebes has six genera 
im Common with Mindanao, of which only two are found in New 
Guinea, while all of them are found in Borneo. 
Thus, of the fifteen genera, only three might be regarded as 
having been derived from New Guinea; these are Phrynixalus, 
Chaperina, and Cornufer. It is significant, however, that single 
representatives of the two genera last mentioned are known in 
Borneo. Eleven of the genera, which are for the most part 
Southern Asiatic or Malayan in distribution, have undoubtedly 
entered our territory from Borneo through the Sulu and Pa- 
Wan groups.
