WHOLE VOL. SKELETAL REMAINS OF EARLY MAN HRDLICKA 287 



Age. — The patent sutures indicate a young adult. The wear of the 

 teeth, if these were for instance Eskimo jaws and the teeth were worn 

 ofif as they are in this individual, would indicate a fully adult stage, 

 though not past the 35 year mark. With a broad leeway the La 

 Quina individual may safely be placed at between 25 and 35 years 

 of age. 



Details: supraorbital arches. — There is complete meeting over the 

 glalx;lla, which itself is slightly elevated ; the arches, which measure 

 15-16 mm. in thickness about the middle, diminish but slightly towards 

 their distal portions. The maximum transverse diameter of the arches 

 reaches only 11.4 cul, which is less than in any of the other Neander- 

 thal adults. 



The forehead is low, sloping, and narrow (see Dr. Martin's measure- 

 ments). The nasion-bregma diameter or arc is longer than in Spy 

 No. I, but on the other hand the sagittal (B-Z) diameter or arc is 

 shorter, the sum of the two being very nearly equal in the two speci- 

 mens. These dimensions, as the student may readily satisfy himself 

 on modern material, are largely of a compensating nature, and no 

 great weight can therefore be attached to either an exceptionally short 

 or an exceptionally long frontal alone. 



The sutures are relatively simple. The parietal region, ovoid from 

 side to side, shows but a slight ridging along the anterior two-fifths of 

 the sagittal. It is remarkably low. The parietal bosses, as in other 

 Neanderthalers, are situated low (only slightly above the mastoid 

 parts of the temporal), though they are relatively a trace less posterior 

 than the Spy No. i and the Neanderthal. The occiput, except for 

 being narrower, is typical neanderthal oid, being moderately prominent 

 with a flattening above and below. There is a rather marked occipital 

 torus reaching on each side the lambdoid suture. The region below the 

 torus is concave in its upper part, indicating the attachment of 

 powerful nuchal muscles. 



The temporal squamae are relatively small ; the root of the zygomae 

 forms a pronounced dull crest ; the zygomae are stout ; the meatus 

 of moderate size ; the mastoids above average feminine or submedium 

 masculine. The temporal fossae were spacious ; but the temporal lines 

 are rather low and but slightly distinct. 



The face. — The orbits are relatively large, high, and irregularly 

 rounded as in the other Neanderthalers. The upper borders are less, 

 the lateral and lower better defined. The nasal process of the frontal 

 was evidently stout. The plane of the orbits, as in other Neander- 

 thalers, was inclined downwards and forwards, and also somewhat 

 more outwards and backwards than in modern skulls. The malars
