bluish beneath. Other specimens agree with these in markings 

 and coloration, according to their age. 



Remarks. — This species is retiring and is seldom observed. 

 It is arboreal in habit, feeding for the most part in the trees. 

 Usually the animals inhabit trees which are densely covered 

 with vines. I had resided at Bunawan, Agusan, nearly a year 

 and a half before specimens of this species were taken, and 

 then they were discovered in a small clump of trees about 200 

 meters from my house. Several specimens were taken.
