198 BATRACHIA SALIENTIA. 
Skin with tubercles, minute on the back and small on the sides; a narrow, more or less 
indistinct, glandular fold on each side of the back. ‘The hind limb, without tarsus, as 
long as, or rather shorter than, the body; fourth toe (from metatarsal joint) five-ninths 
of the length of the body. Brownish, with rounded darker ocellated spots, and generally 
with greyish or whitish dots. Lower parts and thighs punctulated with white; upper 
parts of the legs with irregular dark cross-bars. Also the tympanum is dotted like the 
skin round it. Sometimes uniform brown. 
Male with a large external vocal sac between the angle of the mouth and the 
humerus. 
Length of body of adult female 110 millim., of adult male 70 millim. 
The peculiar coloration of this species is so well described by Troschel that I cannot 
doubt that his Rana adtrita is based upon a specimen of &. montezume. The only 
divergence in his description is that the tympanum is said by him to be smaller than 
the eye-opening.

* According to Garman (Bull. Ess. Inst. xvi. p. 41), Kalm did not use the specific term “ halecina,” but 
commences his specific diagnosis with the word ‘“wirescens.” I am not inclined to assist in substituting the 
latter term for one so generally adopted hitherto.
