In all the skulls except one (No. 48665, cT) the bones of the skull are 

 completely fused; in this the nasal sutures are still open, yet this skull, 

 judging by other features, is one of the oldest of the series. In cranial 

 measurements the sexes are similar, but the small series of females indicates 

 a greater length of forearm than in the males, an apparent difference that 

 would probably disappear in a larger series. The cranial measurements 

 of males and females are practically the same.
