44 LIZARDS OF THE PHILIPPINE ISLANDS 



protective coloration can be discovered only v^ith difficulty. If 

 the collector chances to search the earth below the log or to dig 

 it up, the gecko may even submit to burial without moving. This 

 is especially true of Gymnodactylus annulatus Taylor, a terres- 

 trial species, which is found only rarely in trees. The color 

 and markings are highly protective when on the ground. In the 

 forest, where their chief enemies are wild hogs, it is obvious 

 that these habits and the protective coloration avail much. 



Key to the Philippine species of Gymnodactylus Spix* 

 a\ Males with 4 to 6 preanal pores in an inverted V-shaped groove; 



none in females; no femoral pores G. annulatus Taylor (p. 44). 



a\ Males v^ith 12 preanal pores in a longitudinal groove arranged in two 

 parallel series; no femoral pores; no pores in females. 



G. philippinicus Steindachner (p. 47). 



a^. Males with 8 to 11 preanal pores in a broadly angular series; 9 to 11 



femoral pores widely separated from the former; pores in females 



much reduced in size G. agusanensis Taylor (p. 49).

Description of the species. — (From a large series of speci- 

 mens, including the type, from the type locality, Bunawan, Agu- 

 san, Mindanao.) Head slightly flattened, moderately large, with 

 a shallow depression delineating supraorbital regions and con- 

 tinuing on snout ; depressed area behind nostrils not prominent ; 

 eye comparatively small, its diameter little less than half the 



* Casto de Elera, Cat. Fauna Filipinas 1 (1895) 408-409, includes in his 

 list Gymnoductylus marmoratus, from Luzon and Cavite; G. consohrinus, 

 from Palawan, Samar, and Borongan ; and G. platyurus, from Palawan, with 

 specimens of all in the Santo Tomas Museum. I am inclined to regard these 

 records as doubtful as there are no specimens now in Santo Tomas Museum. 

 However, it is not improbable that the first and the second may be found 

 in Palawan; it is extremely improbable that the third species occurs there. 



Gray erroneously referred the British Museum specimens of G. philip- 

 pinicus Steindachner to Cyrtodactyliis marmoratus Kuhl. I believe no 

 other record of any of these species is to be found. I add the characters 

 of the above species. 



a. Males with 12 or 13 preanal pores in a longitudinal groove, and on 



each side, separated from these, a row of 5 or 6 femoral pores; 

 dorsal tubercles small, roundish, feebly keeled. 



G. marmoratus Kuhl. 



b. Male with an angular series of 9 to 11 preanal pores not inclosing a 



pubic groove; no femoral pores; dorsal tubercles very small. 



G. consobrinus Peters. 



c. Tail as broad as body, leaf-shaped; no preanal or femoral pores. 



G. platyurus White.
