100 LIZARDS OF THE PHILIPPINE ISLANDS 



The ear opening of Gekko mindoremsis is larger, equaling 

 half the eye. The eye itself is much larger than in G. mo- 

 narchus; the inter orbital distance is less ; there are more preanal 

 and femoral pores; the number of scale rows across the belly 

 is about fifteen less; the tubercles are fewer and much less 

 prominent; and the very characteristic markings of Gekko mo- 

 narchus apparently are wanting. The type specimen was cap- 

 tured with the assistance of Mr. Clark Burks, of Sumagui, 

 Mindoro ; two eggs were found at the same time. 



Oshima * has described Gecko kikuchii from Formosa, which 

 seems to vary from Gekko monarchus much in the same way 

 as does the present species. Although no specimen of Oshima's 

 species is at hand for comparison, the following differences are 

 evident; G. mindorensis has many more femoral pores, 55 to 

 64, while 48 are recorded in G. kikuchii. The legs are longer 

 in the present species, and the basal web on the feet is wanting 

 in both sexes.

Digits strongly dilated, entirely webbed, with undivided la- 

 mellae below; distal phalanx of toes compressed, curved, with 

 retractile claw rising a little in front of the end of digital 

 expansion, wanting on inner digits. A broadened cutaneous 

 fringe on either side of head, legs, and body. Body above with 

 small granules, tubercles present or absent; below with im- 

 bricating scales; lateral membranes covered above with rather 

 large scales, scaleless below. Pupil vertical. Male^ with pre-

 fringelike lobes. 



East Indian Archipelago, Malay Peninsula, Formosa, and the 

 Philippines. 



Only a single species is known in the Philippines, the recently 

 discovered Ptychozoon intermedia, which seems to stand between 

 the other two known species, P. kuhli and P. horsfieldii,
