and are much darker than specimens from Mindanao. The 

 white granules on the back form rather indistinct transverse 

 lines. The median double row of black spots is present but 

 dim, with some spots confluent. 



Cosymbotus platyurus Schneider. 



Specimens were taken in Zamboanga, Basilan, Bongao, Simo- 

 nor, and Sitanki. The cutaneous expansion from axilla to 

 groin is apparently wider in these than in specimens from 

 Negros or Manila with which they were compared. 



Hemidactylus frenatus Dumeril and Bibron. 



Very common throughout the Archipelago; numerous speci- 

 mens were taken. 



Peropus mutilatus Weigmann. 



A very common forest species, present on nearly all the islands 

 visited.
