86 LIZARDS OF THE PHILIPPINE ISLANDS 



short, compressed, distal phalanx, with retractile claw ; legs bor- 

 dered with cutaneous lobes; upper and lower surfaces covered 

 with juxtaposed granular scales; pupil vertical; males with pre- 

 anal pores. 



The three species of this genus are confined to the Philippine 

 Islands, 



Key to the species of Luperosaurus Gray. 



a^. No enlarged chin shields. 



6\ Upper labials, 16; lower labials, 14 or 15; (body with lateral fringe?) ; 

 pores present; tail narrow, annulate, the lateral keel with a slight 

 fringe formed by projecting elongate scales. 



L. cumingii Gray (p. 86). 

 h^. Upper labials, 14 or 15; lower labials, 14; preanal pores, 16; tail 

 narrow, depressed, the annuli marked by spinelike scales. 



L. macgregori Stejneger (p. 87). 

 a^ Enlarged chin shields present; upper labials, 11; lower labials, 11; 

 preanal and femoral pores, 31, in a continuous series; tail rather 

 flattened, annulations marked by 2 spinelike lateral scales. 



L. joloensis Taylor (p. 88). 



In the generic description Boulenger* says : "Males with prse- 

 anal pores," but he does not mention the number of scales or 

 pores in the description of the type. The plate giving a figure 

 of the species plainly shows the presence of a lateral fold or 

 fringe. This is not mentioned in the description, as Stejneger 

 points out.f Luperosaurus macgregori Stejneger appears to be 

 rather closely related to L. cuTrdngii save for this difference. 

 No specimens of these very rare species are at hand for com- 

 parison. I refer Luperosaurus compresicorpus Taylor to a new 

 genus, Pseudogekko. It was suggested in the original descrip- 

 tion that this might be necessary.J
