Variation. — This species is a variable one. There are at 

 least four recognized subspecies, three of which are admirably 

 figured by Barbour.* In the Philippines the variations noted 

 do not appear to be geographical, as two or more variations may 

 be found in the same immediate locality. The following local- 

 ities are represented: Palawan, three specimens; Negros, two; 

 Mindoro, one; Luzon, one; Mindanao, fifteen. 



Two color forms are present in the Palawan specimens. Two 

 of the specimens are bluish with a darker wash (in alcohol) , with 

 numerous quadrangular dark spots on back and a dim, elongate, 

 Y-shaped, darker spot on base of tail, and numerous milky blue 

 spots are scattered on side and back. The second form has a 

 greenish blue neck and the shoulders with quadrangular black 

 spots; back with brownish wash and whitish dots; V-shaped 

 mark present ; a dark line along groin continuing on tail : a dis- 

 tinct dark line from snout to ear. 



The Mindoro specimen resembles the second Palawan form, 

 but the quadrangular marks on neck are wanting and there is a 

 series of spots on first half of tail. 



The two Negros specimens differ; the one has black quadran- 

 gular spots over a greenish background, and the tail is light 

 greenish brown with no spots; and the other has a few small
