 Mountains [Serra das OrgSos, Rio de Janeiro], Brazil). 



Description. — Young frog, USNM 97717, Guapi, Teres6polis, Rio 

 de Janeiro. Tongue one-half the width of mouth-opening, spatulate, 

 without indentation on its free posterior border; snout moderately 

 elongate, rounded when viewed from above, slanting forwards in pro- 

 file, the upper jaw projecting slightly beyond the lower; nostrils 

 anterolateral, midway between tip of snout and anterior corner of 

 eye, separated from each other by an mterval equal to Ij^ times their 

 distance from eye. Canthus rostralis bluntly rounded; loreal region 

 flat and sloping outwards a little; upper lip flaring slightly outwards. 

 Eye large and prominent, its diameter equal to its distance from tip 

 of snout; interorbital diameter nearly twice the width of upper eyelid, 

 1}^ times the distance between nostrils. Tympanum hidden. Fingers 

 not v/ebbed, short, the fourth a mere knob on side of hand, fu'st and 

 second very short; subarticular tubercles few but distmct; toes webbed 

 at the base; first poorly developed, third longer than fifth, with dermal 

 fringes apparent; no pronounced inner or outer metatarsal tubercles 

 or tai'sal ridges. Body moderately elongate, iu postaxillary region a 

 little narrower than head width; when hind legs are adpressed, heel 

 reaches to center of eye ; when limbs are laid along the body, knee and 

 elbow touch; when hind legs are bent at right angles to body, heels 

 touch. Skin minutely pustular above; venter also minutely pustular 

 except on the sides and the anus, where larger granules occur. (No 

 vocal sac apparent in the male.) 



Dimensions. — Head and body 12 mm.; head length 5 mm., width 

 5 mm.; femur 5.5 mm.; tibia, 5.5 mm.; foot 4 mm.; hand 2 mm. 



Color in alcohol. — Dorsum wood brown; faint traces of darker cross- 

 bands on legs and arms; venter pale buff. 



Remarks. — The single example in the U. S. National Museum was 

 examined and identified by Parker. It measures only 12 mm. in 

 total length and thus is apparently not fully grown, as the type is 

 18 mm. It agrees well with the description of the type, except in 

 having the eye as long as the snout, to be expected in a young individ- 

 ual, and in having the dorsal pattern very indistinct. There are no 

 vomerine teeth, and the tongue is spatulate and free on its posterior 

 part, which is not indented. The dorsal skin on this somewhat dried 

 specimen appears under the lens to be minutely pustular, with a few 

 weak glandules on the sides.
