dorsolateral line beginning at the tip of snout, continuing above the 

 shoulders, and fading out at midbody; inside of elbow, groin and 

 anterior and posterior femur, inside of tarsus and foot geranium red, 

 lighter on base of webs between toes; posterior half of lateral region 

 with narrow, vertical black bars; posterior surface of femur with 

 similar but coarser light-bordered black bars; outside of tibia with 

 a black, yellow-bordered stripe; heel, elbow, and anal region with 

 black, light-edged patches. Chin straw yellow; belly olive-buff; 

 lower parts of fore limbs pearl gray, of hind limbs pale geranium 

 red; disks of toes and fingers pale olive-buff above and below. Iris 

 dull straw yellow at the center, olive at the periphery; pupil black, 

 transversely elliptic. 



Remarks. — Although both forms of H. bischqffi are closely related 

 to H. raddiana, an examination of the head alone is usually sufficient 

 to separate the two species, as the flaring upper lip and broad head 

 of bischqffi are quite unlike the nearly vertical loreal region and rel- 

 atively narrow head of raddiana.

Description. — Male, IOC (cotype), Bonito, Serra da Bocaina, Rio 

 de Janeiro. Vomerine teeth in two oblique well separated patches 

 between the posterior choanal borders; tongue flattened and very 

 wide, over four-fifths the width of mouth opening, scarcely free be- 

 hind; snout short, slightly truncate at the tip v/hen seen from above 

 and in profile; the upper jaw projecting a little beyond the lower; 

 nostrils lateral, scarcely projecting, their distance from end of snout 

 about one-third their distance from eye, separated from each other 

 by an interval nearly equal to their distance from eye. Can thus 

 rostralis rounded, distinct, loreal region concave and sloping. Eye 

 large, prominent, its diameter equal to its distance from tip of snout ; 

 interorbital diameter equal to width of upper eyelid, which is nearly 

 equal to the distance between nostrils. Tympanum very small but 

 distinct, about one-third the diameter of eye, separated from eye by 

 an interval of more than 1% times its own diameter. Fingers not 

 quite one-third webbed, fourth much longer than second, reaching
