Description. — Adult male, USNM 115606, State of Rio de Janeiro, 

 Vomerine teeth in two small, slanting, widely separated patches on 

 the inner border of the choanae; tongue rounded, very slightly in- 

 dented on its free posterior border, about one-half the width of mouth- 

 opening; snout fairly long, rounded when seen from above, sloping 

 forwards in profile, the upper jaw slightly projecting beyond the 

 lower; nostrils superior, scarcely projecting, situated on the sharply 

 ridged, straight canthus rostralis three-fifths of the distance from 

 snout tip to eye, separated from each other by an interval a little 

 greater than their distance from eye; loreal region concave and slop- 

 ing outwards. Eye quite small but prominent, anterolateral, its 

 diameter equal to its distance from nostril; interorbital diameter 

 1% times the width of upper eyelid (minus the horn), equal to interval 

 between nostrils. Tympanum very distinct, separated from eye 

 by an interval equal to lYi times its greatest diameter. Fingers free, 

 with dermal ridges along their sides, their tips not dilated, fourth 

 much longer than second, first slightly longer than second; two 

 heavy rounded tubercles on palm and on base of first finger; toes 

 webbed at the base, not dilated, fifth a little longer than third ; a large 

 shovellike inner metatarsal tubercle; outer tubercle greatly reduced 

 in size; a very heavy inner tarsal ridge beginning above shovellike 

 tubercle and ending before the heel. Body very stout, in postaxillary 

 region as wide as the very broad head; when hind leg is adpressed, 

 heel reaches to axilla; when limbs are laid along the sides, knee and 

 elbow are widely separated; when hind legs are laid at right angles 

 to the body, heels fail to meet. Skin of upper parts heavily glandular, 

 with distinct ridges bordering the dark dorsal spots on the bony 

 shield; blunt tubercles on posterior part of back and on the sides; 

 venter nearly smooth, with faint glandular patches on sides behind 

 axillae ; a heavy, bony ridge along upper lip border, bifurcating below 

 loreal region and sending its upper branch to the supratympanic 

 region, lower branch continuing to corner of mouth; another less dis- 

 tinct ridge below eye, and another from nostril forward to upper lip 

 ridge; eyelid with a single short dermal horn. No apparent skinfold 

 across throat.
