FOSSIL REMAINS OF MAN. 153 



and there is an unusually deep vascular groove immediately 

 behind the coronal suture, which, as it terminates in a 

 foramen, no doubt transmitted a vena emissaria. The 

 course of the frontal suture is indicated externally by a 

 slight ridge ; and where it joins the coronal, this ridge 

 rises into a small protuberance. The course of the sagittal 

 suture is grooved, and above the angle of the occipital 

 bone the parietals are depressed.
