free upon the half of its length. The eyes are of medium size, ellip- 

 tical in form, their longitudinal diameter being equal to the distance 

 between their anterior rim and the extremity of the snout. The inter- 

 ocular space is broader than the eyelid. The nostrils are elevated, 

 situated at the upper, terminal end of the snout, though equidistant 

 between the eyes and the margin of the upper jaw. There are no 

 parotid glands. The tympanum is entirely hidden under the skin. 



The forelegs are almost exiguous, and, though short, reach the 

 groins when brought backwards alongside with the body. The 

 fingers are subcylindrical ; the first one longer than the second, which 

 is nearly equal to the fourth ; the third being the longest. The arti- 

 culations are all provided beneath with conspicuously developed 

 tubercles, and the tip of the fingers slightly swollen beneath, into a 

 tuberculous-like knob. Smaller tubercles may be seen on the palm 

 of the hand, arranged in series in the direction of the fingers, each 

 series composed of at least two tubercles. There is a comparatively 

 large, horny, metacarpal disk, and a horny knob at the base of the 

 first finger. The hind legs are slender but not very long ; measured 

 from their origin to the base of the fifth toe, they equal in length the 

 head and body together. The toes exhibit the same structure as the 

 fingers ; there are but a few small granules on the sole of the feet, 

 situated towards the base of the toes. The inner metatarsal tubercle 

 is elongated ; the outer one is rounded. The inner edge of the tarsus 

 exhibits a very inconspicuous horny ridge. 



The skin is smooth, although provided above with small pustules, 

 spread over the head, body, and legs, though fewer on the latter. 



The ground color above, is greenish-brown. A deep chestnut-brown 

 vitta starts from the margin of the upper jaw, ascends the snout 

 towards the nostrils, thence along the line of the canthus rostralis to 

 the eye, and passing over the latter, extends obliquely down to near 

 the insertion of the anterior limbs. A transverse brown patch is 

 observed upon the occiput, between the eyes. A larger patch of the 

 same color is seen on the anterior portion of the trunk, and another 

 still smaller, upon its posterior portion. These three patches are 

 united together by means of diverging, narrow branches, giving the 

 back a stellated appearance. Transverse narrow bars of brownish- 

 black are observed upon the legs, more conspicuously on the poste- 

 rior than on the anterior ones, where two such bars only are seen. 

 The hands and feet above are maculated. Underneath, the color is
