A "HAIRY" FROG FROM THE GERMAN CONGO 



Owing to the extraordinary development of tubercles on the 

 skin, this species seems to have hair. The hair-like 

 appendages appear to be a peculiarity of the males 

 only, and to be most highly developed among adults, and 

 at the breeding season. They apparently serve as sensory 

 organs, and are to be considered a secondary sexual 

 characteristic, but their exact purpose is a matter on 

 which one can hardly even guess with profit. From 

 Kiikenthal. (Fig. 10.)
