Variations. — Two other specimens have been captured: one, 

 an adult from Tawitawi; the other, a young example from 

 Papahag. The first specimen does not differ from the described 

 specimen save that the black spots on the back form continuous 

 dotted lines, and there is a bright orange band along the side 

 (greenish in alcohol). Throat bluish with indistinct bluish 

 longitudinal lines; labials with black spots; tail flecked with 

 white. The young specimen is olive green, with a broad black 

 stripe beginning behind the eye; sides of neck and body green- 

 ish; below greenish white. De Rooij, (op. cit.) states that the 

 range of scale rows is between thirty and thirty-six.
