 one or two large pea-green spots below the eye; sometimes a small 

 brown spot just behind the ear; prefrontals seldom touching the 

 canthals; 22-26 lamellae on the fourth toe; hind leg adpressed reaches

 anterior more faintly; three scales (an internasal and 2 prefrontals) 

 between the rostral and the supraorbital ring; posterior prefrontals 

 much the larger; nasals in contact with rostral; internasals somewhat 

 elongate, barely separated from each other by the first of the series 

 of three medial scales; prefrontals separated from the canthals by a 

 relatively large wedge-shaped scale ; two heavy rounded can thai scales
