220 LIZARDS OF THE PHILIPPINE ISLANDS 



Color in life. — A bright golden brown above with four heavy 

 black stripes from head to base of tail; the two median stripes 

 begin on anterior part of supraocular region and continue 

 practically the same width to base of tail, and they usually 

 continue some distance on tail as dim dotted lines; the two 

 lateral stripes begin on point of snout, continue through eye, 

 and along side to above hind leg ; belly yellow to pinkish brown ; 

 chin and throat more or less speckled with brown; tail usually 

 pinkish brown above and flesh pink below ; labials spotted brown ; 

 digits with brown crossbars.

Variation. — A few differences in coloration are discernible 

 in the specimens at hand. Some specimens have a heavier wash 

 of brown on the tail; the continuation of the median stripes on 

 the tail is variable; sometimes even the dotted lines are absent, 

 or dim. In certain specimens there is indication of a banded 

 arrangement of the brownish coloration on the tail ; in two spec- 

 imens there are faint suggestions of longitudinal lines on the 

 belly. Specimens from the Sulu Archipelago are usually darker, 

 and the markings frequently appear as three yellow to golden 

 brown stripes on the back; the sides of the neck, the chin, and 

 sometimes the sides are dark, specked with white. In scalation 

 the chief variations are in scale rows and the number of lamellae 

 under the fourth toe ; the length of the legs and the proportional 

 length of the fourth and third toes vary. Only one specimen 

 has twenty-two scale rows; the others have twenty. In each 

 of them there is a distinct depression marking the position of 

 the auricular opening. The longest is 90 millimeters long ; snout 

 to vent, 41 millimeters. 



Remarks. — This species is commonly found under bark on 

 dead trees and stumps, where it remains concealed, feeding on 

 the larvae of beetles and other insects which live in such local- 

 ities. I have never observed it crawling in daylight unless 

 routed from its natural habitat. 



It is not rare at Bunawan, at Zamboanga, or in the Sulu Ar- 

 chipelago. I have failed to find specimens in any other local-
