I shall now pass over to a more minute description of the dif- 

 ferent parts of the cranium. Seen from above, (Text-fig. 11 and PI. 

 III., fig. 1), the brain-ease exhibits a symmetrical, broad oval outline on 



which the well developed pa- 

 rietal eminences are plainly 

 marked, while the frontal emi- 

 nences are very slightly pro- 

 nounced. The form agrees 

 best with the »typus sphénoï- 

 des» proposed by Sekgi, or 

 the »forma cuneato-ovata» of 

 the older authors. The sagit- 

 tal suture is almost wholly 

 obliterated. The coronal su- 

 ture is somewhat indistinct in 

 its middle portion; below the 

 temporal line, the highest point 

 of which is about 59 ram, from 

 the median line, it is comple- 

 tely obliterated. The incon- 

 siderable height of the cra- 

 nium is apparent from the 

 side-view (Text-fig. 12 and 

 figs. 3 on PI. II. and III.). The 

 profile of the forehead conti- 

 nues rather slantingly above

the well pronounced superciliary ridges, with a somewhat sharper 

 turn at a height level with the frontal eminences, up towards the re- 

 of the vertex, where the highest point of the curve lies about 3 

 behind the bregma. At the lambda there is a moderate bathro- 

 cephalie projection, below which the occipital bone projects outwards 

 and downwards more than usually, its convexity being quite great 

 also below the inion. The relatively great development of the back 

 of the head is also evidenced in the comparatively important part 

 taken by the occipital bone in the formation of the sagittal circumfe- 

 rence. The curve of the occipital bone (136 mm.), namely, occupies 

 more than \'3 (35 i°/o) of the entire distance from the root of the nose 

 to the foramen magnum. In this connection should also be mentioned 

 that the height of the skull-eap (Schvvalbe's »Kalottenhöhe ;>) is 109 mm,
