GYMNODACTYLUS 49 



taken in Mindoro are very much darker above and below; one 

 young specimen, locality unknown but said to be Dumaran Is- 

 land, near Palawan, is almost black with deep black bands; the 

 belly also is black. This locality is doubtful. 



Remarks. — This species is distinctly larger than G. annulatus 

 Taylor and differs also in the arrangement of the preanal pores ; 

 in color and markings they are quite similar. Individuals are 

 most frequently encountered under the loose bark of trees near 

 the ground. They take fright easily, apparently not relying 

 much on protective coloration to escape observation. In Min- 

 doro the species was common about Lake Naujan; in the moun- 

 tains of Negros it was rare. It is known from Luzon, Mindoro, 

 Polillo, Dinagat, and Samar and probably is confined to the 

 Philippines.*

 90. 



Description of species. — (From a series of specimens, includ- 

 ing the type from Bunawan, Agusan, Mindanao.) Head large, 

 oviform, with a depressed area above delineating supraorbital 

 regions and continuing some distance on snout; depressed areas 

 behind nostrils giving the appearance of a ''nose;" eye very 

 large, its diameter only slightly less than its distance from nos- 

 tril, which equals distance of eye to auricular opening; depth of 

 head in occipital region equals length of snout ; auricular opening 



* Boettger, Abh. Senckenb. Ges. 20 (1900) 332, lists Gymnodactylus phil- 

 ippbiicus Steindachner from Halmahera. De Rooij, Rept. Indo-Aust. Arch. 

 1 (1915) 17, says: "At a closer examination of a specimen preserved in the 

 British Museum and four specimens of the Senckenberg Museum in Franc- 

 fort, named by Boettger G. philippinicus, I came to the conclusion, that they 

 did not belong to that species, but were most probably G. fumosus, slightly 

 different from the typical Celebes-specimens. The dorsal tubercles are 

 somewhat larger and more numerous; the ear-opening is oval, oblique. 

 That they could not belong to G. philippinicus, was evident at first sight, 

 because the last-named species has a pubic groove with two parallel series 

 of six preanal pores, and the subdigital transverse plates scarcely differ 

 from the surrounding scales." 



It is doubtful whether de Rooij has bettered matters by referring these 

 specimens to G. fumosus Miiller, since that species, according to the same 

 author, has "a pubic groove and a continuous series of 42^52 pores, pierced 

 in enlarged scales, which are visible in the female." Boettger specifically 

 states that his specimens have seven to thirteen preanal pores in an 

 angular inverted V-shaped row. It may in fact be related more closely 

 to G. annulatus Taylor, but this I cannot affirm.
