The table shows the principal variations. The number of 

 supraoculars is variable. The type has only four supra- 

 oculars. 14 



In the type the hind leg is said to reach the axilla. I found 

 this to be the case in only very young specimens. None of the 

 specimens listed here has the toes of the hind leg reaching much 

 beyond the elbow of the adpressed foreleg. All the specimens 

 agree with the type in color. 



Tropidophorus grayi Giinther.

This species was found to be very common on Polillo Island, 

 but is apparently absent from Calotcot Island, lying east of 

 Polillo. The latter condition is probably due to the fact that 

 there is no standing or running water on the island. A few 

 specimens were obtained on Mount Maquiling and on Mount 

 Mariveles. Gregorio Alforo y Lopez collected a single specimen 

 of the species at Cabalian, Leyte.

One small specimen has five instead of four labials preceding 

 the large subocular labial on one side. The same specimen also 

 has each frontoparietal broken into two scales. The Leyte spec- 

 imen differs from the specimens from Polillo and Los Banos 

 in having slightly longer toes with five more lamellae than the 

 average for the more northern specimens. The height of the 

 spiny keels on the neck and back is distinctly greater. 



"Boulenger, Cat. Liz. Brit. Mus. ed. 2, 3 (1887) 254, states that the 

 supraoculars are 5. The drawing, pi. 17, fig. 1, leads me to believe that 

 the "first very small" supraocular should be regarded as a superciliary.
