Remarks. — As may be noted from the measurements, there is a 

 considerable amount of variation in size of these bats. On the basis 

 of size, Thomas described Rhinopoma cystops from Luxor, Egypt. 



This species may be distinguished from the smaller R. cystops by the 

 longer forearm, darker coloration, and larger skull in all measurements 

 taken.
