to and almost parallel with the sagittal suture ; however, the supra- 

 orbital margins on both sides and the foramen magnum are intact. 

 The skull has distinctly the characteristics of a male. The cranial 

 capacity is approximately 1,.~><IO c.c., and by estimating the circumfer- 

 ence from the sound half we get a total hori/ontal circumference of 

 ;")30 mm. 



Xornxt I'crtit-tf/in. The massive supraorl>ital ridges and external 

 angular processes enter into this view, and certainly the /ygomata 

 had they been entire would have been concealed. The vertex 

 is 3f> mm. behind the hregma, and from this point the surfaces of 

 the skull descend uniformly and rapidly in all directions. The maxi- 

 mum breadth is well down the parietals. The breadth is relatively 

 great, the cranial index being 85' 1. 



NoriiiK LatiTnli* (Plate IV., Fig. 1). This view is very striking 

 on account of its apparent great height. The real height is, however, 

 diminished by the rapid way in which the occipital bone shelves in- 

 wards and forwards below the inion. The supraorbital ridges are 

 prominent and overhanging. The outline of this view is high and so 

 rounded as to form practically the segment of a circle. The parietal 

 arc in this skull is 14 mm. longer than the frontal arc. 



Xoritui QecipitaKs. The parietal eminences are well out and be- 

 low them the lateral walls of the skull widen slightly as they descend 

 toward the mastoids, so that the greatest breadth is near the squamous 

 sutures. 



Nonnn l^icialis. The brows are beetling and the face wide and 

 square-looking. The malar bones are not prominent. The gnathic 

 index is low, being only 90'6. The orbits are microseme and the nasal 

 aperture is almost broad enough to be reckoned platyrhine. 



Norma lidxil/irix. The foramen magnum is rounded and the 

 anterior ends of the occipital condyles are far apart. The palato-max- 

 illary index is 107 "(5. 



The other bones of this skeleton are much broken. The hyoid 

 bone is complete and is a delicate well-marked bone. There is also 

 an ala of the thyroid cartilage almost completely ossified.
