Description. — Adult female, USNM 96313 (cotype of Ceratophrys 

 fusciventris), Tijuca, city of Rio de Janeiro. Vomerine teeth in two 

 very long, posteriorly converging, nearly contiguous series well behind 

 the choanae; tongue three-quarters as wide as mouth-opening, round, 

 fairly free posteriorly and slightly so anteriorly due to its attachment 

 on a stalk (as in Craspedoglossa) ; snout very short and rounded when 

 seen from above, somewhat trimcate in profile, the upper jaw not 

 projecting beyond the lower; nostrils lateral, slightly projecting, their 

 distance from end of snout about two-thirds that from eye, separated 

 from each other by an interval 1% times as great as their distance from 

 eye. Can thus rostralis low and rounded; loreal region concave and 

 nearly horizontal due to the extreme flaring out of the upper hp. Eye 

 small, anterolateral, with a large meniscus on upper border of pupil; 

 eye diameter a little greater than its distance from nostril ; interorbital 

 diameter twice the width of upper eyelid, equal to interval between 

 nostrils. Tympanum not visible. Fingers free, not fringed, their tips 

 blunt, not dilated, second longer than first and equal to fourth, extend- 

 ing to base of penultimate phalanx of third; no pronounced pollex, but 

 palmar and subarticular tubercles moderate; a very distinct fold of 

 skin along the sides extending from the groin nearly to the elbow and 

 forming an axillar wing; toes without webs, fringes, or disks, third 

 longer than fifth, reaching to base of antepenultimate phalanx of 

 fourth ; a prominent blunt oval inner and a small rounded outer meta- 

 tarsal tubercle; a very indistinct inner tarsal ridge; body quite stout, 

 in postaxillary region a httle less than the width of the very broad head; 

 whan hind leg is adpressed, heel reaches to posterior tympanic region; 

 when limbs are laid along the sides, knee and elbow fail to meet ; when 

 hind legs are laid at right angles to body, heels just meet. Skin of 

 upper parts fairly smooth except for some minute glandules on top of 

 head and tibia; a heavy semicircular fold from posterior corner of eye 

 encircling tympanic region and ending in front of shoulder; another 

 heavier glandular fold originating on the posterior corner of the eyeUd, 

 nearly converging between the shoulders, then abruptly diverging and 

 continuing longitudinally nearly to the groin; ventral surface smooth 

 excepting for a granular postanal patch. (A slight skinfold across the 

 throat but apparently no external vocal sac in the male.) 



Dimensions. — Head and body length 20.5 nun.; head length 8
