broken up into small scales or granules; subocular bordering the 
lip ; temporal scales smooth ; front edge of the ear not denticulated. 
Dorsal scales perfectly smooth, rhomboidal, flat, larger on the middle 
of the back. Ventral plates much broader than long (the largest at 
least twice ay broad as long), in straight longitudinal and transverse 
series; 10 plates across the middle of the body. A median series 
of broad preanals, posterior largest. The hind limb reaches the 
axilla or the collar. Digital denticulations very feebly developed, 
as in A. vulgaris. The scales on the basal third of the tail, above 
and inferiorly, perfectly smooth. Greyish, brownish, or reddish 
above, sides and limbs with round white spots; back with black 
spots, which may be very small and irregular, or large and in lon- 
gitudinal series.
