Description. — Adult male, USNM 98245, Pirapora, Miuas Gerais. 

 Tongue elongate, spatulate, oue-third the width of mouth-opeaing, 

 free behind; snout short, truncate at the tip when viewed from above 

 and in profile, very much swollen in the nasal region; upper jaw pro- 

 jecting considerably beyond lower; nostrils almost at the tip of snout, 

 more superior than lateral, horizontal, bounded beneath by a heavy 

 bony ridge, separated from each other by an interval equal to their 

 distance from eye. Canthus rostralis marked by a thin curving ridge, 

 forking in front of the eye to form a strong continuous ridge in front 

 of and below eye and a narrow supraocular ridge which continues 

 behind the eye, bifurcating into a rather weak parietal ridge and a 

 strong supratympanic ridge which merges with the small parotoid 

 gland; no definite curved row of tubercles from corner of mouth to 

 parotoid. Eye large and prominent, its diameter equal to its distance 

 from end of snout; interorbital region concave, its width Iji times that 

 of upper eyelid, and twice that of interval between the nostrils. Tym- 

 panum small, distinct, its diameter one-half that of eye, separated 

 from eye only by the narrow postocular ridge. Fingers free, with 

 serrated lateral fringes, not dilated, first and second subequal, shorter 

 than fourth, which reaches to base of penultimate phalanx of third; 

 no pronounced pollex; an oval tubercle on base of first finger and a 

 much larger round one on palm; subarticular tubercles prominent, the 

 proximal ones single, the distal ones double; toes one-third webbed, 

 fringed, their tips not dilated, third slighth^ longer than fifth, reaching 

 to base of antepenultimate phalanx of fourth; inner and outer meta- 

 tarsal tubercles subequal, conical, small but prominent; subarticular 

 tubercles not well distinguished from the other metatarsal warts, 

 apparently single proximally and double distally; no pronounced 

 tarsal ridge. Body stout, in postaxillary region about 1)4 the greatest 

 head width; when hind legs are laid along the sides, heel reaches almost 

 to posterior tympanic border; when limbs are laid along the sides, 

 knee and elbow fail to meet; when hind legs are bent at right angles to 

 the body, heels touch. Dorsal skin closely set with tubercles, some 

 larger ones between the shoulders; no especially heavy sacral gland; 

 venter finely gi-anular anteriorly, coarsely so on posterior abdomen and 

 lower femur; parotoid glands elongate, straight, extending as far back 

 as the axilla, coarsely tuberculate. A loose fold of skin at center of 

 throat marking the presence of an external vocal sac.
