distance behind the eye is present in all the specimens, but the 
narrow fold behind it is not so evident. Some of the specimens 
have numerous tubercles between the eyes and on the snout; in 
others they are largely wanting. Specimen 356 shows no char- 
acteristic mark on the back. I find no vocal sacs in any of the 
specimens. 
Remarks.—The type and three cotypes were collected in 
southern Polillo along the trail between Polillo and Bislian at 
a point near where the trail crosses the low divide. A single 
specimen was collected by Dr. F. X. Williams in mountains near 
Mauban, Tayabas, on the eastern coast of Luzon. This speci- 
men is rather different in color and markings, but there are no 
structural differences save those that may be accounted for 
by the state of preservation. The species is named for Dr. F. 
X. Williams, of the Hawaiian Sugar Planters’ Association, who 
collected the Luzon specimen. I believe that this is the first 
record of a species of Philautus for Luzon.
