Variation. — Two other specimens have been examined; an 

 adult from Tawitawi and a young example from Papahag. The 

 first specimen does not differ from the one described, save 

 that the black spots on the back form continuous lines and that 

 there is a bright orange band along the side (greenish in al- 

 cohol) ; the throat is bluish with indistinct bluish longitudinal 

 lines; the labials have black spots, and the tail is flecked with 

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

 stripe beginning behind the eye ; the sides of neck and body are 

 greenish, and below it is greenish white. De Rooij * states 

 that the scale rows range between thirty and thirty-six.
