FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 217 



15 mm.; tympanum 4 mm. The original description is in error in 

 stating that the length of the femur and tibia together is less than the 

 length of the body. 



Color in alcohol. — Dorsum much faded but generally wood brown; 

 posterior femur with traces of wide dark and light longitudinal stripes; 

 inner surface of tibia with coarse dark reticulations; venter pale, 

 immaculate. 



Remarks. — A cotype of Pseudis fusca was compared with a cotype 

 and other examples of P. bolbodactyla. It is apparent that fusca is a 

 more heavily built frog, with thicker femur and tibia. Even the carpal 

 areas are more swollen than in bolbodactyla. While the skin of 

 fusca appears smoother than that of bolbodactyla, the great age of the 

 specimen may have caused the granulations on the back and legs to 

 become less apparent. It is unfortunate that no additional examples 

 of fusca have come to light since the original description appeared. 



The Rio Sao Francisco, in the tributaries of which P. bolbodactyla 

 was discovered, and Rio Arassuahy, the home of fusca, are not more 

 than 150 mUes apart at then- nearest points, but they are separated 

 by ranges of high mountains and hence are in totally different water- 

 sheds. The geographical separation between fusca and bolbodactyla 

 is complete, and the physical differences between them seem to be 

 great enough to warrant their being considered as distinct species.
