NYCTERIDiE 25 



from Barberton, Woodbush, and Wakkerstroom by Mr. 

 C. H. B. Grant, while Mr. K. B. Woosnam wrote that 

 he found some hundreds on the rocks in a shaft of an 

 old gold mine near Kuruman, and that they are common, 

 but only found in caves and similar localities. 



I collected some in a deep underground cave at 

 Hennops River, in the Pretoria district, where this 

 species and several others were very common, and their 

 guano formed a layer on the floor from 18 inches to 

 8 feet thick.
