aurignacensis but not so marked as in Heidelberg Man. The 

 limbs of the dental arches are divergent owing to the consid- 

 erable basicranial breadth and the arches themselves are 

 squarer. All the teeth show a well-marked neck at the gingival 

 line and the roots are long and unfused. All the incisors are 

 stout, relatively large and long rooted teeth and the crowns 

 are vertically placed. The upper teeth overlap the lower very 

 slightly. The spatulate form of the upper median incisors is

very pronounced and in these as well as in the laterals the 

 long axis of the root forms an angle with that of the crown, a 

 secondary specialization also found in the great modern An- 

 thropoids. The cingulum is elevated into a small palatal cusp 

 more pronounced in the lateral than in the central upper in- 

 cisor. The canines are stout teeth projecting only slightly 

 beyond the general occlusal plane. The maxillary canines 

 possess a very pronounced palatal cingular cusp connected
