with cactus and small trees. We stayed only a few hours, and 

 this appeared to be the best collecting ground. Hunted under 

 the loose lava, and found geckos fairly common. They were 

 most abundant along the edge of the cliffs, where the sea-birds 

 nested. They were nearly all. good-sized specimens that seem 

 full-grown, and are the first ones on which I noticed claws. 

 Lack of time prevented me from collecting more specimens. 

 The elevation of this plateau is about two hundred feet" 

 (Slevin). 



General remarks. — This is a very distinct species. In it, as 

 in the geckos of Chatham and Barrington islands, the en- 

 larged dorsal tubercles are much reduced in number. It agrees 

 with P. tuberculosus in the possession of enlarged subcaudals, 

 but is, I believe, closely related to the other geckos native to 

 the archipelago.
