Remarks. — The species is known by the unique type spec- 

 imen, collected by Dr. E. A. Mearns, U. S. A., Malindang Moun- 

 tain (338 meters altitude), Misamis Province, Mindanao, May 

 24, 1906. 



In the collection which I made in the mountain near Zam- 

 boanga during the month of September, 1917, a specimen of 

 what was very probably this species was captured. It agreed 

 in having the lips and underside of head dark, and the fronto- 

 parietals divided. Unfortunately the specimen escaped from a 

 faulty collecting bag. No other specimen was seen. The 

 character of the temporals seems to differentiate this species 

 from the many other small Philippine skinks. The species is 

 very probably confined to western Mindanao.

 small, much narrowed laterally in front of first labial; fronto- 

 nasal broader than deep, forming a rather broad suture with 

 rostral and a smaller suture with frontal; prefrontals about 

 half the size of frontonasal, separated, not in contact with 

 supraocular; frontal longer than wide, about equal in width to 

 supraocular region, in contact with two supraoculars; fronto- 

 parietals large, distinct; interparietal large, the parietals form- 

 ing a moderate suture behind it; nostril pierced in middle of 

 nasal; two frenals, first as high as nasal and narrower, second 

 slightly broader and lower than first; two unequal-sized pre?- 

 oculars between first superciliary and third labial, lower much 

 the larger ; a row of small suboculars separates labials from 

 orbit ; four large supraoculars, first longest, second widest, these
