182 LIZARDS OF THE PHILIPPINE ISLANDS 



Mount Maquiling, Luzon; and from Mindoro. They vary as 

 follows : 



Canlaon specimens. — The anterior frenal consists of either a 

 single vertical scale or two superimposed scales (44 per cent 

 show the latter condition) ; the second loreal is small and is 

 never in contact with the labial. The specimens reach a larger 

 size, and are darker in color. The median dark line has the 

 appearance of being continuous with a chain of lighter spots 

 on it ; the limbs are shorter in proportion to the size of the 

 body ; the adpressed limbs do not meet ; the male has a brilliant 

 rose red spot below the neck, and the belly is canary yellow; 

 usually black spots are present on the preanal scales; the pre- 

 frontals occasionally are separated. Fifty-five specimens were 

 examined. 



Mindoro specimens, — The specimens here agree well with 

 those from Negros. In the four specimens examined from this 

 island the frontal is broken and forms a small, regular scale 

 between frontal and prefrontal.* The markings are very 

 similar. 



Butuan specimens. — Ten specimens of this form were col- 

 lected in the swamps near the town of Butuan, Mindanao. The 

 f renals are normal ; that is, both are vertical and both in contact 

 with the labials ; the color is chestnut brown ; the body is slender- 

 er, and the tail elongate. The snout and body appear slenderer 

 and more elongate than in the typical form. 



Mount Maquiling specimens. — Eight specimens were collected 

 on Mount Maquiling. These on the whole are smaller than other 

 specimens; the markings are very similar to those of the type 

 form. The frenals are vertical, both touching the labials. 



Remarks. — It is possible that some of these forms might 

 profitably be separated into species or subspecies, since to the 

 eye they appear distinctly different. However, the absence of 

 stable characters to define these differences causes me to wait 

 until specimens from more localities are available.

 Sphenomorphus llanosi Taylor, Philip. Joum. Sci. 14 (1919) 121, pi. 2. 



Description of species. — (From the type, an unnumbered spec- 

 imen in Santo Tomas Museum, Manila; collector unknown; 

 probably from Luzon.) Habit lacertiform; snout narrower 

 and longer than in Sphenomorphus jagorii; rostal much wider 



* This same curious anomaly occurs in specimens of S. jagorii divergens, 

 found in the same locality.
