in 96447, owing perhaps to a different mode of preservation, and the 

 dark dorsal tone is very sharply set off from the light ventral tint, 

 apparently not by color alone but by a difference in skin textm-e, as 

 the dorsal and upper lateral regions have a thick, glandular covering, 

 while the ventral surfaces are covered by translucent, thin skin, 

 although this may be dotted in certain regions by heavy aggregations 

 of granules. A light brown band leaves the posterior corner of the 

 eye, beginning again behind the tympanum and continuing along the 

 posttympanic skinfold to the shoulder and fading out as a series of 

 brown dots bordering the juncture of dorsal and lateral colors on the 

 sides. This specimen has the following measurements: head and 

 body 37 mm.; head length 12 mm.; head width 12.5 mm.; femur 15.5 

 mm.; tibia 16.5 mm.; foot 13.5 mm.; hand 9.5 mm. 



Remarks. — Accompanying the adult from Teres6polis are five tad- 

 poles of various sizes and six eggs in which different developmental 

 stages may be seen. The egg-yolk with the larva already in an ad- 

 vanced stage appears to be about 4 mm. in diameter, the gelatinous 

 envelope adding another 2 or 3 mm. The smallest of the young 

 tadpoles is 13 mm. in total length, of which head and body make up 

 4 mm. A highly advanced tadpole, with all four limbs well developed 

 and the tail partly absorbed, measures 35 mm. in total length, the 

 head and body 18 mm. The adult male is only 37 mm. in length, 

 so that the metamorphic frog is almost half as long by actual measure- 

 ment. The eggs are laid in leaves of small plants overhanging the 

 water, about 50 to each ball of gelatin. In two or three days after 

 laying, the tadpoles flop themselves out of the egg mass into the 

 water. The time occupied by entire metamorphosis is not known. 



The species is not common, having been found near running water 

 first in Sao Bento and later in Teres6polis. Its voice is like that of 

 P. guttata and is described as a long rasping sound followed by two or 

 three clucking notes. It is closely related to guttata, but the two can 

 be quite easily distinguished by the structm-al characters of amount 

 of webbing and shape of snout, as well as by color pattern.
