spine. The canine fossae are slightly depressed. Malar tuberosities 

 prominent, and zygomatic arches outstanding. 



Norma Verticalis. — Oval in outline, with prominent parietal tubera 

 but very slight frontal development. The temporal fossae are broad 

 and deep, the superior temporal line passing within 45 mm. of the 

 sagittal suture, just behind bregma. The bizygostephanic index 

 is 78. • 



Norma Posterior. — Of well marked pentagonal form, with straight 

 sides and broad base; the asterionic diameter is 116 mm., as com- 

 pared with 131 mm. for the maximum cranial breadth. 



Norma Lateralis. — The depression at nasion is very striking, 

 owing to the excessive development of the glabella. The forehead 

 retreats very rapidly behind ophryon and the apex of the curve is 

 reached about 40 mm. posterior to bregma. The occipital squama is 

 almost vertical. 



Norma Inferior. — Foramen magnum slightly rounded, measures 

 33 x 29 mm.; basilar process short and narrow. 



Sutures. — Coronal exceedingly simple; sagittal and lambdoidal 

 coarsely serrated. Synostosis has partially taken place in the coronal 

 below pterion and in the posterior third of the sagittal. There is a 

 small wormian bone in the lower left lambdoidal and one in the lower 

 temporo-parietal suture near asterion. 



Processes. — The mastoids are exceptionally massive and rough; 

 the external occipital protuberance is very large and is expanded 

 laterally into a torus occipitalis transversus. 



The external pterygoid plate has a broad lateral expansion, with 

 long sphenoidal spines. Especially massive and prominent is the 

 frontal external angular process. 



Muscular Impressions. — The temporal lines are prominent and 

 broad, with strong ridges on the mandibular angle. 



Lower Jaw. — Strong and clean cut. Mandibular angle 112 . 

 Symphysial height, 35 mm. 



B. FEMALE CRANIA. 



NO. 40,607.— Skull of adult female. The right and left lach- 

 rymal and the left 6s planum of the ethmoid bone, together with the 

 turbinals and vomer, have been destroyed. Cranial capacity 1,275 cc. 

 The teeth present are well formed, in perfect condition and but very
