90 LIZARDS OF THE PHILIPPINE ISLANDS 



Measurements of Luperosaurus joloensis Taylor. 



mm. 



Total length 59 



Snout to vent 36 



Tail . 23 



Width of head 5.5 



Length of head 10 



Axilla to groin 17 



Foreleg 10.5 



Hind leg 14.7 



Variation. — A second specimen captured in the same im- 

 mediate locality is a male, and consequently differs from the 

 type (which is an adult female containing undeveloped eggs) 

 in the presence of distinct femoral and preanal pores. There 

 are thirty pores in a continuous series from knee to knee, 

 forming a distinct arch in the preanal region. The tail is 

 missing. The color is brown with a wide occipital spot of gray 

 and black mixed, and five irregular bands of gray and black 

 intermixed across the back; length from snout to vent, 27 

 millimeters. 



Remarks. — This species differs much from other Philippine 

 species of the genus. The presence of chin shields, spinelike 

 scales on side of neck and head, the much lower number of 

 labials, and the large number and the arrangement of the fem- 

 oral and preanal pores are all distinctive characters. 



These two specimens were taken at Siet Lake, Jolo,* September 

 22, 1917. The female, which had evidently been running on the. 

 bole of a large dapdap tree, first made its presence known by 

 jumping on my shoulder and escaping to the ground where it 

 was later captured. The male was taken at the foot of the same 

 tree in a pile of rocks.

* Siet Lake is a small crater lake situated in the central northern part 

 of Jolo, only a few hundred meters from the coast. A small Constabulary 

 Post is maintained there. The post is situated on the edge of the crater 

 on a side which juts into the lake, forming a small promontory. It was 

 in this exact locality that the types were collected.
