FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 349 



its diameter a trifle shorter than snout; interorbital diameter equal 

 to that of upper eyelid and to that of interval between nostrils. 

 Tympanum faintly visible on right side in this specimen, hidden on 

 left side. Fingers moderately long, free, with faint lateral ridges, the 

 tips ball-like but not enlarged into disks, second a little shorter than 

 fourth and longer than first; metacarpal and subarticular tubercles 

 well developed; no antebrachial tubercles; toes webbed at base with 

 narrow but distinct lateral fringes, their tips rounded but not dilated, 

 third shorter than fifth, reaching beyond the base of antepenultimate 

 phalanx of fourth; a prominent inner metatarsal and a much smaller, 

 rounder outer one; a small conical tarsal tubercle about midway on 

 the inner tarsal border; a flat irregularly shaped inguinal gland. Body 

 rather slender, in postaxillary region about equal to head width ; when 

 hind legs are adpressed, heel reaches to center of eye ; when limbs are 

 laid along the sides, knee and elbow barely touch ; when hind legs are 

 bent at right angles to the body, heels considerably overlap. Skin of 

 upper parts finely glandular, with a heavier row on each side of the 

 back posteriorly; a low curving supratympanic fold ending above 

 shoulder; ventral surfaces pustular, more coarsely so on posterior 

 throat and abdomen; region around anus weakly granular; skin of 

 belly very loose, forming a large ventral disk. A very heavy external 

 vocal sac beginning behind the corners of the mouth and extending 

 entirely across the throat. 



Dimensions. — Head and body length 26 mm.; head length 8.5 mm., 

 width 8.5 mm.; femur 11 mm.; tibia 13.5 mm.; foot 15 mm.; hand 7 

 mm. 



Color in alcohol. — Wood brown above, slightly paler on the belly; 

 a dark line across loreal region from nostril to eye; a dark area cov- 

 ering the inguinal gland. 



Variations. — The Nova Teutonia specimen, USNM 103684, is slate- 

 black above; the tympanum is black, and a down-curving black 

 lateral stripe extends from it onto the sides, edging the heavy lateral 

 fold below. The upper arm, posterior bellj^ and proximal femur are 

 drab-gray, the belly with many black spots becoming coarser an- 

 teriorly, but with a slight median line on the chest, which the spots 

 do not invade. The throat and chin are black, including the heavy 

 diagonal folds of the vocal pouch that in development somewhat sug- 

 gest those of Lcptodactylus sibilatrix. The femur towards the knee 

 becomes spotted with fine slate dots. The concealed anterior part of 

 the femur, also the inside of the tibia, are sabnon color. The upper 

 surfaces of legs and forearms have diagonal black crossbars. A very 

 heavy ventral disk is present in the male.
