This skull is an exceedingly light one, and less marked in the extent of its 

 deformation than either of the previous specimens. 



In norma verticalis it is a medium ovoid, and in norma lateralis presents 

 the bregmatic svi^elling between two depressions already described for i and 2. 

 The bony ridges are poorly marked; the sutures open. A right-angled bend in 

 the coronal suture at the bregma indicates an original articulation between the 

 right parietal and the left frontal. Epipteric bones are developed in both 

 pterionic angles. On either side at least three epipteric laminae are super- 

 imposed, those on the left side being the larger. 



The parietal eminences are strongly marked and 

 their prominence accentuated by the marked com- 

 pression grooves passing on either side from the 

 ])ost-bregmatic area to the occipital bone midway 

 between the lambda and the mastoids. One exceed- 

 ingly small right-sided parietal foramen is present ; 

 the main blood return probably having been by 

 means of a large median foramen in the squama of 

 the occipital bone that emptied into the torcular 

 1 lerophili. 



The lambdoid suture is extremel}- serrated, and encloses several large 

 W orniian bones more or less symmetrically disposed. 



There is no torus occipitalis. 



The orbits are unequal in size, being 3 t W, 3-2 H (right) and 34 \\", 

 ^■2 11 (left). The supraorbital ridges and glabella are slight. The supraorbital 

 nutcli is duplicated on the right, and on the left there is a broad shallow groove 

 surmounted by a "foramen. Infraorbital sutures are present on both sides, anil 

 tlie malar bones are excluded from the inferior orbital fissure by frontosphenoidal 

 sutures. The lacrimo-ethmoidal sutures are very narrow. The nasal aperture 

 is pyramidal and sharp edged. .\ prominent subnasal spine overhangs small 

 praenasal depressions, and is continued down as a slight median ridge.
