332 Records of the S.A. Mx'seum 



])efore backwards and from side to side. Anteriorly, there is no evidence of 

 the metopic suture, and the glabella and superciliary ridges are markedly devel- 

 oped. The coronal suture is sharply inclined posteromedially, very slightly 

 dentated in its f^ars hrci/iiuitica. and somewhat more so in its pars complicata. 

 At either stciiiiaiiidn. irregular stellate Wormian bones have been developed, 

 and at tlie left pterion is a large "Os epiptericuin." The ]3arietal eminences 

 have been completely obliterated, the greatest width falling below the squamoso- 

 parietal suture. In the sagittal suture at the obelion there appears one large 

 median parietal foramen. 



The occipital bone, narrow, elongated, and flat, meets the parietals in a 

 \crv denticulated lambdoid suture, marked by a Wormian on the right side, 

 and, well up in the angle included by the converging arms of the suture (slightly 

 to the left of the midline) presents a flattened circular exostosis I to 2 cm. in 

 diameter. 



.\ small dro]5-like exostosis appears on the posterior aspect of the right 

 mastoid. 



Grooves of com])ression are obvious, and proceed from the frontal to the 

 occipital bones continuously. From before backwards one notes the frontal 

 depression, the bregmatic swelling, and the post-bregmatic depression, already 

 referred to as appearinp; in distorted skulls of the couche type. Midwav between 

 the laml)da and the mastoids on either side is a marked groove broad and shallow, 

 tending to disappear posteriorly. 



The orbits vary in width, lieing 3-8 cm. (right) and 4-1 cm. (left), while 

 the height of each is 3 4 cm. 



The superior orbital margin recedes slightly, exposing the fossa for the 

 lacrimal canal : on either side there is a very narrow lacrimo-ethmoidal suture 

 marking a .strong tendency towards a fronto-maxillary union. The lacrimal 

 bones are continued forward to the anterior aspect of the inferior orbital margin 

 by means of an interposed ossicle. 



On the left the supraorbital notch is present, on the right a tri-radiatc 

 foramen, the infraorbital suture is ossified on both sides. The malar bone 

 enters into the formation of the inferior orbital fissure laterally: the zygomata 

 are widely separated from the infratemporal fossae, the skull being phaeno- 

 zvgous. 



The nasal aperture is pyriforni and its lower margin infantile. A prominent 

 nasal s\m-\e overhangs small praenasal fossae. All but five teeth have been 

 lost post mortem ; these are sound, well-rooted, and are free from disease, as is 

 also the alveolar margin.
