262 LIZARDS OF THE PHILIPPINE ISLANDS 



of one; there are five body scales bordering the interparietal, 

 seven including the superior postoculars; the rostral is some- 

 v^hat rugose; there are twenty- four and twenty-six scale rows 

 about the body ; both specimens are females ; the largest measures 

 154 millimeters, and the tail length is contained in distance 

 from snout to vent 6.7 times. The silver blotches are confined 

 to the anal region and the tail; the head is widened behind 

 the angle of the mouth. 



The Papahag specimen is a male and consequently differs 

 from the preceding specimens in the presence of leg rudiments ; 

 these are small flaps about 3 millimeters long which fold 

 back, their tips almost in contact behind the anus; they are 

 covered with scales; the terminal scale is single; the preanal 

 scales are drawn out to a sharp point, the scales bordering the 

 anus small, with two much-enlarged scales behind them, between 

 the bases of the leg rudiments ; there is a single postocular ; the 

 prefrontal is proportionately narrower than the interparietal; 

 two large silver blotches are present, one on the anterior part 

 of the body, the second on the tail ; the tail length is contained in 

 the body length 6.7 times. The Bornean specimen is very small, 

 but has the silver blotches. 



Remarks. — All the specimens were found under fallen logs, 

 except the Bornean specimen, which was found burrowing in 

 sand at the base of a tree. 



This species differs from Dihamus nov^-guinea in the mark- 

 ings and the proportionately longer tail. In D. novse-guinea the 

 length of the tail is contained in the body more than nine times. 

 The length of the frontal and the interparietal together is in- 

 variably less than the length of the rostral from the frontal 

 to the end of the snout.
