of differentiation of the small scales that border the posterior 
part of the mouth, after the mouth curves upward. There are 
three or four small scales bordering the rostral behind. There 
are eighteen to twenty-two lamelle under the longest toe, the 
variation being chiefly in the basal count. The arrangement 
of the preanal and the femoral pores varies in some individuals. 
In a few of the specimens the line curves distinctly upward at 
the beginning of the femoral pores. In others no such curve is 
evident. There are eighteen to twenty-three pores on each side. 
The coloration was practically uniform in the specimens when 
they were first taken. Some of the specimens have more black 
spots on the head and the anterior part of the body than others. 
Remarks.—The species was discovered on a species of large 
Caladium. The specimen took refuge under water which was 
held in the petiole of a huge leaf. All other specimens were 
taken from Pandanus trees which were growing along small 
streams. The spiny-leaved trees were cut and allowed to fall 
in the water. The specimens were finally driven from their 
hiding places in the leaf axils and forced to swim to land. These 
spiny Pandanus trees were splendid collecting places and har- 
bored, besides the described species, several species of frogs and 
lizards, 
- This species belongs to the section of the genus Gekko which 
includes G. swinhonis and is characterized by the absence of 
tubercles on the back. The number and arrangement of the 
preanal pores and the very distinctive markings easily separate 
the species. Many differences are evident from a comparison of 
descriptions. It would appear that the species is very closely 
associated with the Pandanus trees. This association may 
account for the fact that it has not been collected before.

Ptychozoon intermedia TAYLOR, Philip. Journ. Sci. § D 10 (1915) 
95; Lizards of the Philippine Islands (1922) 101. 
A female specimen of Ptychozoon intermedia Taylor (No. 
1075), taken near Zamboanga, agrees with the type specimen 
taken in eastern Mindanao, save that there are no rounded 
tubercles on the back. Each annulation on the tail is marked 
posteriorly with enlarged spinous tubercles, much as is the type; 
the granules on the neck and the back are smaller. The scales 
under the tail are divided into two rows of enlarged scutes, 
while in the type occasional scales are not divided, and others 
are divided into more than two parts.
