scales. Twelve rows of ventral plates. Brachials rather small, in 

 seven rows above, and two below, not separated from antebrachials 

 by granules, but joining an area of small scales in seven rows above, 

 and ending in one row of broad and one of narrow antebrachials 

 below ; postbrachials small, three rows larger ; tibial plates in four 

 rows, two on under face, the outer of seven plates, of which the

Nostril in the anterior nasal ; three supraoculars ; five supra- 

 ciliaries, second longest ; median gular scales minute, those of the 

 mesoptychium larger, in six rows. Ten longitudinal rows of ventral 

 plates. Prteanals in a series of three or four large marginal, one or 

 two large median, longitudinally arranged. Three (two small, one 

 large) antebrachial series, scarcely continuous with brachial row ; 

 postbrachials small, in three short rows ; femoral plates numerous ; 

 external tibial plates seven, very wide, second, third, and fourth 

 largest, third broad, fourth narrow, transverse ; a slight tendency 

 to acumination in the heel-scales of some specimens. External toe 

 extending beyond extremity of internal. Femoral pores eighteen. 

 Two indistinct light bands — the superior from the supercilium, the 

 interior from the superior margin of the auricular opening — enclose 

 a black band, which is continued some distance upon the base of the 

 tail, with its inferior light border ; beneath greenish or yellowish 

 white, the pectoral and gular regions more or less black. The female 

 differs in having the brown of the back lighter and marked with a 

 narrow median line. The black upon the throat is also sometimes
