rotten stumps, and in other similar habitats. These differ from 

 the type specimen in having fewer preanal pores. There are 

 three to five pores, four being the usual number. Slight differen-

Gekko gecko Linnseus. 



Specimens were taken on Jolo, at Siet Lake and Camp Roman-

 scales perforated, and they resemble the preanal pore scales 

 of the males, save that the perforations are distinctly smaller. 



Gekko monarchus Dumeril and Bibron. 



Two specimens were obtained on Bongao at an elevation of 

 about 500 meters. They were found hiding under the loose bark
