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. Praanals 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 
wanting.
