Closely allied to A. swrinamensis, from which it may be distin- 
guished by the following characters:—Nostril pierced in the posterior 
border of the anterior nasal; fifth toe relatively longer, reaching 
quite as far as the inner; mesoptychial shields a little larger; one 
row of brachials and two of antebrachials, widely separated by 
several rows of scales ; three rows of tibials, outer very large, inner 
very small; a regular transverse row of eight or ten posterior pre- 
anal plates, decreasing gradually in size from the centre; femoral 
pores very numerous, twenty-eight (twenty-four according to 
Dumeéril and Bibron). The colour is described as rubiginous olive, 
with light spots on the loins, limbs, and tail. 
From snout to vent 107 millim.

Nostril in the posterior border of the anterior nasal; five occi- 
pitals ; four supraoculars; seven or eight supraciliaries; loreal un- 
divided; six or seven upper labials. Five or six lower labials; 
chin-shields, one anterior and four or five pairs; a few slightly 
enlarged gular scales forming a small group on the middle of the 
throat ; mesoptychium with several rows of enlarged scales, which 
are larger than the median gulars. Dorsal granules small, smooth. 
Ventral plates in ten or twelve longitudinal rows; thirty-four to 
thirty-six transverse rows. Three enlarged median preeanal plates, 
forming a triangle. A single row of humeral plates, more or less 
distinctly continuous with the antebrachials, which are in two rows ; 
postbrachials small. Six or seven rows of femoral shields; two or 
three rows of tibial shields, the outer extremely large, the inner, if 
present, very small and irregular. Femoral pores thirteen to seven- 
teen. Digits feebly serrated, fifth extending quite as far as inner. 
Caudal scales keeled. Olive-brown above; a series of black spots 
on each side of the body; flanks, hind limbs, tail, and sometimes 
hinder part of back, with numerous round white spots; lower sur-
