processes, but the styloids were apparently not much developed, a 

 condition often observed in the Indian. The petrous portions are 

 seen in a moderate depression between the basilar process and the 

 sphenoid, about as in the average Indian." 



Yentrally may be seen a moderately high metopic crest; impressions 

 of brain convolutions are perceptible, especially over the orbital roof, 

 but are not pronounced ; the sella turcica is normal, the clinoids are 

 rather stout, the anterior and posterior lxing united on the left : the 

 dorsum sellae shows in its superior border a deep (4 mm.) median 

 notch. 



The thickness of the frontal bone is not greater than in many 

 Indian crania (see measurements). 



There are traces of the nasal suture, but its exact state can not be 

 determined ; the naso-maxillary and the naso-frontal articulations 

 seem to be patent on both sides; the malo-frontals show no oblitera- 

 tion; there is no trace of metopic separation; the spheno-frontal, 

 which can be seen on the left, seems to show some synostosis, but the 

 spheno-malar and the spheno-temporal sutures appear open; there 

 are no signs of obliteration in the coronal and in the right spheno- 

 parietal suture, and the same statement applies to what remains of 

 the right temporo-parietal and the temporo-occipital articulations. 



Irrespective of its large defects, the specimen shows remarkably 



few injuries, and it is wholly inconceivable that it should have been 



rolled about in a stream bed or subjected to pressure in gravel deposits. 



The measurements permitted by the condition of the skull are as 



follows :

" In undeveloped and low-form crania the inferior surface of the petrous bones IB on a 

 level with the neighboring surfaces, while In the best developed skulls of whites and 

 other races the petrous portions appear deep In a depression.
