BATRACHIAAyOURA. 39 



are a little nearer the orbits than the margin of the upper jaw. The 

 eyes are subelliptical, of medium size. The eyelid is perfectly 

 smooth above, like the upper surface of the head. The tongue is 

 subelliptical, slightly notched posteriorly as well as anteriorly. The 

 vomerine teeth are disposed upon two oblong groups, situated be- 

 tween the inner nostrils, quite apart from each other, almost trans- 

 versal, the anterior extremity of each group reaching the inner 

 margin of the latter openings, which, themselves, are quite conspi- 

 cuous, well proportioned to the average size of the animal, and subcir- 

 cular in shape. The openings of the Eustachian tubes are quite small. 

 The tympanum is very small, its diameter being less than half that 

 of the eye. 



The body is elongated, subcylindrical, broader anteriorly than the 

 head, tapering posteriorly, though in general appearance raniform. 



The limbs are rather slender ; the anterior ones, when bent back- 

 wards alongside to the body, are made to reach the groin with 

 the extremity of the fingers ; the latter are subcylindrical, slightly 

 swollen upon their extremities, and provided under their articulations 

 with small rounded tubercles ; the second and fourth are equal in 

 length, and shorter than the first. The palm of the hand is tubercu- 

 lous; the first finger possesses a large, basal, and oblong tubercle; an- 

 other, still larger tubercle, may be seen at the base of the carpus. The 

 land legs are longer than the body and head together, for the whole 

 length of the toes and metatarsus. The toes are subdepressed, 

 bordered with a membranous fold, and slightly webbed at their base. 

 Their articulations are provided underneath with small tubercles; a 

 few granules may occasionally be seen on the sole of the feet. The 

 metatarsal tubercle, at the base of the first toe, is large and con- 

 spicuous, whilst the other is quite small. The tarsus is provided 

 inwardly with a cutaneous fold, and the leg, from the knee to the 

 tarsus, has a conspicuous, floating membrane, outwardly. 



The skin is generally smooth all over the head, body, and legs. 

 Occasionally small pustules are observed on the dorsal region and on 

 the sides of the abdomen. 



The lumbar glands are large and ovoid. 



The ground color is reddish or greyish-brown, maculated with deep 

 chestnut-brown. The maculae on the upper parts of the body are 

 either distinct or confluent, always very irregular in shape or out- 

 lines. The dorsal blotches may be margined with a light whitish line ;
