FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 249 



indentation on its nearly attached posterior margin; snout bluntly 

 pointed when seen from above, slanting backwards to the upj 3r lip in 

 profile, the upper jaw extending far beyond the lower; nostril lateral, 

 scarcely projecting, about three-fifths the distance from eye to tip of 

 snout, separated from each other by an interval equal to 1}^ times 

 their distance from eye. Canthus rostralis prominent but rounded, 

 the loreal region vertical, with a slight groove on its lower edge where 

 the upper lip projects slightly outwards. Eye large and prominent, its 

 diameter equal to its distance from end of snout; interorbital diameter 

 equal to width of upper eyelid, about three-fourths the distance be- 

 tween nostrils. Tympanum large and very distinct, one-half the 

 diameter of eye, separated from eye by an interval equal to one-third 

 its own diameter. Fingers free, their tips very slightly dilated into 

 disks which all have a pair of rather indistinct pads divided by a faint 

 median longitudinal furrow on top and a transverse groove across the 

 upper part of the joining between the last two phalanges; second and 

 fourth fingers subequal, reaching to base of penultimate phalanx of 

 third; a wide dermal fringe on the margins of fingers and toes; no 

 pronounced pollex, but a rounded palmar tubercle and another below 

 first finger; subarticular tubercles single, prominent; a patch of five or 

 six small black spines on the outer side of first finger; toes webbed at 

 the base, their disks with very prominent pads and a median furrow; 

 the transverse groove across upper part of toe between each two 

 terminal phalanges followed by a pad, causing the tei-minal phalanx of 

 toes as well as fingers to bend forward (in a preserved specimen) at a 

 right angle to remainder of digit; third toe much longer than fifth, 

 reaching to base of penultimate phalanx of fourth; a sharp oval inner 

 and a smaller round outer metatarsal tubercle; a wide dermal flap 

 along inside of tarsus; body stoutly built, in postaxillary region a 

 little wider than greatest width of head; when hind leg is adpressed, 

 heel reaches to between eye and nostril; when limbs are laid along the 

 body, knee and elbow overlap; when hind legs are bent at right 

 angles to body, heels just touch. Skin of upper parts quite smooth 

 anteriorly, a few scattered tubercles appearing on the sacral region 

 and becoming more concentrated on the sides; a slight ridge encirchng 

 the upper part of tympanum and ending above the shoulder in a low 

 glandular swelling with a large gland in front of it behind comer of 

 mouth; ventral surface smooth except for a small granular postanal 

 patch. No external vocal sacs, but forearm and upper arm greatly 

 enlarged. 



Dimensions. — Head and body 29 mm.; head length 11 mm., width 

 10.5 mm.; femur 14 mm.; tibia 14 mm.; foot 14 mm.; hand 7.5 mm. 



Color in alcohol. — Head and back uniform slate-gray above; a white
