FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 203 



in color pattern from the typical Rio de Janeiro guttata, because it 

 has a very heavy marbling of dark (maroon purple in alcohol) spots 

 along both sides of femur and tibia, and similar but smaller spots on 

 upper arm and along inner forearm, the spots being particularly dark 

 and conspicuous on upper surface of hand and foot. The dark spots 

 on the sides of the body tend to a more linear arrangement, while 

 their upper edges are sharply set off by a narrow white line which 

 originates behind the angle of the mouth and continues down the sides 

 to the groin, then along femur and on tibia where the narrow glandular 

 ridges appear. Some slight differences in proportion also exist; the 

 adpressed heel reaches the nostril in the Serra da Bocaina frog, due 

 to an apparently greater tibial length, since the overlapping of heels 

 is greater when hind legs are bent at right angles to body. The toes 

 and fingers of this specimen also appear more slender than in the 

 Rio de Janeiro specimens, but this m.ay be due to the obvious drying 

 out of the specimen. In a series of newly metamorphosed frogs, 

 USNM 96551-6, accompanying the one from Serra da Bocaina, just 

 discussed, nearly all show a trace of marbling on the legs also, but 

 this pattern is not well developed in the young at that stage, as two 

 others, USNM 96548-9, from the same place fail to show it. 



Without additional adidt material from Serra da Bocaina or the 

 neighboring territories, it does not yet seem feasible to bestow a 

 subspecific name based on the specimen mentioned above, or to apply 

 to it the name fimbriata proposed by Miranda-Ribeiro (1923, p. 4), 

 based on a frog from Alto da Serra, Sao Paulo. 



Remarks. — Dr. A. Lutz found this species to be fairl}'" common near 

 mountain brooks in the States of Rio de Janeiro and Sao Paulo. The 

 adults habitually sleep in the daytime. The voice is the same as that 

 of P. appendiculata and P. rohdei, a long rasping sound followed by 

 two or three clucking notes. 



No eggs of this species have yet been collected, but numerous funnel- 

 mouthed tadpoles have been taken in eddies at the foot of cascades. 

 The tadpoles can easily be seen hanging from the surface by their 

 funnels. 



The smallest tadpole, one of USNM 96227, collected on February 

 25, has a total length of 33 mm.; the head and body, exclusive of 

 mouth-disk, being 12 mm.; at this stage the posterior limb buds are 

 just beginning to appear. The mouth is on the upper surface of the 

 head, equipped with a black serrate beak very much like that of 

 ordinary tadpoles, while above the beak is a single transverse row of 

 heavily pigmented teeth which may be broken at the midline, and 

 below the beak two other rows of teeth, the inner one usually discon- 

 tinuous in the middle. The membranous disk has four elongate 

 glands leaving the region of the beak diagonally, and numerous small
