Closely allied to A. surinamensis, from whicli it may be distin- 

 guished by the following characters: — JN^ostril 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 prae- 

 anal plates, decreasing gradually in size from the centre ; femoral 

 pores very numerous, twenty-eight (twenty-four according to 

 Dumeril and Bibron). The colour is described as rubiginous olive, 

 with light spots on the loins, limbs, and tail. 



Prom snout to vent 107 millim.
