FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 195 



Sacral diapophysis dilated and directed backwards. 



Anterior limb short, not reaching to end of urostyle with tip of third finger when 

 adpressed backwards against the body. Fingers without webs, provided with 

 adhesive disks a little smaller than the tympanum, in the following order of size: 

 2,1,3,4. [His figure of the hand shows the following order of size: 2, 1, 4, 3.] 

 Inner surface of fingers, Hke palm of hand, provided with a series of callosities of 

 irregular size and shape. Posterior limb, when adpressed along the body, passing 

 beyond eye with the heel. Toes very deUcate, with adhesive disks on the tips 

 smaller than those of fingers. The four last phalanges are united by a membrane 

 which does not reach the distal end of the first phalanx. Toes in following order 

 of size: 1, 2, 3, 5, 4. Sole of foot and inner surface of toes with a series of irregular 

 callosities less evident than those on inner surface of fingers and palm of hand.

A large pouch on the back [in the female], almost double the width of abdomen, 

 including all the upper surface from shoulders to coccyx. The opening of this 

 pouch is median, consisting of a longitudinal slit beginning anteriorly as a 

 Y-shaped convergence that limits a wedge of concave margins insinuated within 

 the pouch opening. The transparent dorsal wall permits a series of 12 embryos, 

 completely formed and measuring approximately 5 mm., to be seen clearly in the 

 interior of the pouch. In the midline the margins of the pouch fold inside verti- 

 cally, forming a double partition that does not reach to the depths of the pouch. 

 On the inside and bottom of the pouch the dorsal skin lies in folds forming the 

 cellules in which the embryos are lodged. 



The ventral skin of the type is shghtly granular on the abdomen and gular 

 region; smooth on both surfaces of limbs and upper part of head. 



Generally light straw color, much discolored by the action of light, so that no 

 vestiges of the spots mentioned by Mirando-Ribeiro in his description of 1920 

 may be perceived. . . .

Bokermann reports four additional male frogs of this species from the 

 Organ Mountains, State of Rio de Janeiro, in which the color pattern 

 is still perceptible. The ground color of all specimens is dark yellow. 

 In the one appearing as figure 4 in Bokermann's paper, there are two 

 interrupted dark lines extending from the nostrils to the anal region 

 on each side of and near to the midline. One of the others has a dark 

 line between the eyes, and two more lines from the posterior comers 

 of the eyes reaching to midbody.
