NO. I THE HYFOTROCHANTEKIC FOSSA HRDLICKA 49 



The incidence and development of the fossa shows also some sex 

 and side differences, but these are neither very marked nor of great 

 importance. 



The future of the hypotrochanteric fossa in man probably will be, 

 in general, a gradual further diminution in both its incidence and 

 development.
