FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 33 



twice as long as broad and taper posteriorly, their tips extending well 

 beyond the axilla; parietal crests indistinct; a heavy curved ridge 

 along the upper lip; interocular space smooth, flat, much below the 

 level of the ridges. Eye moderate, not projecting beyond the heavy 

 crests surrounding it, its diameter equal to three-fourths its distance 

 from end of snout; interorbital diameter twice the width of upper 

 eyelid, nearly twice the interval between the nostrils. Tjanpanum 

 rather small, distinct, higher than wide, its vertical diameter nearly 

 two-thirds the width of eye, separated from eye by a space equal to 

 half its own diameter, including the postocular ridge. Fingers free, 

 distinctly fringed, first much longer than second, which is shorter 

 than fourth; no pronounced pollex, but a wart at base of first finger 

 and a larger one on palm of hand ; subarticular tubercles well developed, 

 the basal ones single and quite large, the others double and smaller; 

 toes one-third webbed, fringed, third longer than fifth, reaching 

 slightly beyond base of antepenultimate phalanx of third ; a prominent 

 oval inner and a much weaker outer metatarsal tubercle; subarticular 

 tubercles like those of the fingers; a very sharp inner tarsal ridge 

 fading out halfway to heel. Body stout, in postaxillary region Iji 

 times the greatest width of 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 bent at right angles to body, 

 heels fail to meet. Skin of dorsum rough with large and small warts 

 mostly tipped with small black spines, the central area of the back 

 fairly smooth, with the large warts arranged in an irregular row on 

 each side of the faintly indented midline, the warts on the sides and 

 limbs small, fairly uniform in size and closer together, some of these 

 forming a partial lateral row behind each parotoid; upper eyelid set 

 with many conical sharp spines; a pair of heavy ) (-shaped scapular 

 ridges standing out from the plane surface behind the head; a very 

 heavy gland along the top of the tibia extending from just behind the 

 knee almost to the heel, deeply pitted like parotoids; ventral surface 

 covered almost uniformly with polygonal granules, each of which has a 

 central black spiny point; lower surface of tibia nearly smooth. No 

 skinfold across the chest. Apparently a very slight external vocal 

 sac, indicated by a transverse fold across the throat; thumb of male 

 with a heavy black area in the breeding season. 



Dimensions. — Head and body 170 mm.; head length 43 mm., 

 width 66 mm. ; femur 64 mm. ; tibia 6 1 mm. ; foot 58 mm. ; hand 40 mm. 



Color in alcohol. — Ground color above sepia, with an irregular 

 seal-brown spot on each side of the back near the ends of the scapular 

 ridges; a pair of smaller )(-shaped spots at the beginning of the lumbar 

 region, and a few less distinct paired spots behind the parotoids and 

 along the dorsolateral region and usually coloring the base of the
