94 LIZARDS OF THE PHILIPPINE ISLANDS 



on back ; the underside of the body is more or less peppered with 

 brown ; the tail is dark below. The tubercles on these specimens, 

 both of which are females, are much less prominent. 



Remarks. — This species attains a length of at least 205 milli- 

 meters. It is domestic in habit and is also found under the loose 

 bark of trees. 



The specimens of this species apparently are most numerous 

 in the southern part of the Philippine Archipelago. The species 

 is reported from Dinagat by Giinther and from northwestern 

 Mindanao by Boulenger. I collected four specimens at Buna- 

 wan, Agusan, Mindanao; two in Bongao, near Tawitawi, Sulu 

 Archipelago; and one in Negros. In all of these localities the 

 species seemed rare. 



Giinther says: 



This species attains to a length of 7 inches; the newly hatched animal is 

 2i inches long. * * * Cantor says that this species possesses the power 

 of changing its ground-color in a greater degree than any other gecko. It 

 is very numerous at Pinang, swarming at night in rooms occasionally giving 

 out a sound resembling the monosyllable "tok" repeated six or eight times 

 with increasing celerity. They are pugnacious among themselves, two or 

 more sometimes fighting for an insect. 



In Mindoro (possibly also in Luzon) this species seems to be 

 replaced by a closely related form having a very much larger 

 number of pores. T have seen no specimen from Luzon, but 

 Stejneger * reports one from Calayan Island, Babuyanes, north 

 of Luzon, collected by Richard C. McGregor. 



The species is widely distributed in the East Indian Archi- 

 pelago. It is known from Celebes, Borneo, Java, Sumatra, Malay 

 Peninsula, and even Ceylon.
