Tiie muzzle is not prominent, and does not project beyond tlic»ii)per 

 lip. The eantiius rostrales are straij^ht, and tlie top of tiie head is Jlat. 

 The tympanic disk is a vertical oval, of whicii tiie sliort diameter is 

 one-half the lengtii of the eye. Tlie edjjo of tiie vomerine patciies of 

 teeth are a little posterior to the line eoiinectinn" tli«^ posterior border of 

 the uares. The latter are about as larjje as tlie ostia pharyii^i'ca. 



The dorsolateral plandular ridj-'e is tiiit^k, and extends a little beyond 

 the sacrjil diapophysis. There are si.x or seven rows ol short loii<,'itudi- 

 nal glandular tubercles in the space between them. There are similar 

 elongate warts on the sides. The posterior and posteroint'erior faces of 

 the femora finely granular; rest of the inleiior sui faces smooili. 



The first finger is longer than the second, and «'(pials the fourth. The 

 heel of the extended hind leg reaches to the middle of the eye. The 

 foot is of moderate length. Three of the phalanges of the f'oiirih digit 

 are entirely free, and the web is excavated to opposite the middle of 

 the first phalange, extending as a margin on each side of the distal 

 half. The inner cuneiform tubercle is not large, and has an acute 

 apex; no external tubercle. A slightly defined tarsal dermal ridge. 



In alcohol the ground color is light brown, with the tloisolateral 

 ridge and the inferior surfaces straw-color. The spots are a darker

 sjwts are irregularly rounded, and are in three or four longitudinal rows. 

 There are two rows on the top of the muzzle and head, crossing the 

 inner edge of the eyelid. There are two Rjmts near the external edge 

 of each eyelid. Spots on the sides smaller, in about four lows. The 

 lores and upper lip are rather coarsely marbled with brown; gular 

 region faintly speckled with the same. No band, but a sjxit on the 

 front of the humerus; a spot on the elbow, and three cross lines on the 

 fore-arm. Four narrow cross bars on the femur and five across the 

 tibia. Three cross-bars on the external side of the tarsus and five on 

 the external face of the fourth toe. The i)osterior face of the fenmr
