lightening to buff on throat, with many small black spots everywhere; 

 anal region and lower surface of tarsus Indian purple, the glandular 

 ridge edging these areas anteriorly white; iris pale wood brown tinged 

 with drab, the iris black and vertical. 



From a living specimen, USNM 97243, from Manguinhos, the 

 following color notes were taken on the date of its death, June 21, 

 1935: Dorsum and upper limbs between citron yellow and apple 

 green, spotted posteriorly and on the snout with small gray dots. 

 Throat, anal region, and heels below pale malachite green, chest and 

 belly pale orange-buff. Webs of fingers and toes as well as entire 

 anterior and posterior distal parts of femur brilliant cadmium orange. 

 Outer ring encircling iris marine blue. Iris cinereous. Pupil black, 

 vertical, opening from a narrow slit to an elliptical shape. 



Variations. — In a series of 18 adults from near the city of Rio de 

 Janeiro, the relative stability of the specific characters is well attested. 

 The relatively large head and the enlarged disks of fingers and toes 

 are quite apparent in well-preserved specimens, while the dark, coarse 

 network pattern on femur, sides, and forearm appears on every unfaded 

 specimen. The tongue is subject to some variability in size, and this 

 does not appear to be entirely due to the mode of preservation. For 

 instance, in USNM 96123 the tongue is only slightly over one-third 

 of the mouth-opening, while in USNM 96124 from the same lot the 

 tongue measures a full two-thirds of that distance. A very slight 

 indentation is sometimes visible on its posterior border. The usual 

 slight differences in femur and tibia length appear in the series. In 

 color, some are more heavily patterned than others. On loreal region 

 and under eye and tympanum a few short gray longitudinal lines are 

 sometimes present, being made up of the fusion of gray dots which in 

 other examples a,re scattered in this region. In a few examples, a 

 distinct white line appears on the upper eyelid, widening above the 

 ear and continuing over the shoulder until it is invaded by the black 

 dots and later by the coarse network on the sides. The ventral 

 surface may be nearly immaculate, or rather heavily spotted with 

 dots and dark vermiculations. A few black spots occur irregularly 

 on the back of some individuals. On the whole, the species is easily 

 recognizable a.nd seem^s to vary little. 



Remarks. — A topotype of Bradymedusa moschafa, USNM 101721, 

 corroborates Mertens' supposition that moschata is identical with 

 rohdei, described only a day earlier. 



In captivity this frog appears to sleep steadily all day and wakes 

 at night. It has often been collected in and near the city of Rio de 

 Janeiro, where it is not rare. The eggs are laid on leaves, often of 

 orange trees. A cluster of about 40 eggs, USNM 96210, was taken 

 at Amorim in January 1926. The eggs measure 2 mm. in diameter,
