Nasion-opisthion arc ' 37.4 



Nasion-bregma 12.4 



Bregma-lambda - 12.9 



Lambda-opisthion, about 12. 1 



Transverse arc, approximately 30. 8 



The bones of the vault are rather above medium in thickness, tlie 

 left parietal above and along the squama measuring from 6 to 8 mm., 

 the frontal 8 to 9 mm., with the occipital in places less, in others 

 slightly more massive. 



All the above features are of ordinary nature, especially when the 

 skull is compared with those of Indians, and there is nothing that 

 indicates geologic antiquity. 



Specimens marked "Post-pamiJean fossil man from Bio Dulce de 

 Santiage, 2 leagues north of the haths of Rio Hondo. Carles 2d journey." 



STiull A. — An adult male skull of an individual beyond middle age. 

 Shows marked occipital flattening. The bones are yellowish and 

 grayish on surface, nearly wlrite on fracture. They are not mineral- 

 ized and the skull is not, so far as can be judged by hand, of more 

 than ordinary weight. 



The skull is large and shows no primitive characteristics. The 

 supraorbital ridges were not excessive; the forehead is well arched; 

 and there is a rather heavy occipital torus. The face and base are 

 wanting. 



Measurements : 



cm. 



Diameter antero-posterior from ophryon 18. 3 



Diameter lateral maximum 15. 8 



Height, biauricular line, bregma, api)roximately 12. 7 



Diameter frontal minimum 9.9 



Skull B. — This is a mascuhne cranium of an adult near middle a^e. 

 It is in general well-developed but presents a moderate occipital 

 flattening. The bones are brownish on the surface and fragile but 

 are not perceptibl}^ mineraHzed. The specimen has been partially 

 restored. The gla])ella and a part of the right supraorbital ridge 

 have been gnawed away to some extent, although the loss of sub- 

 stance is not deep. 



Principal measurements: 



cm. 



Diameter antero-posterior maximum, about 17. 9 



Diameter lateral maximum 14. 2 



Basion-bregma height, approximately 13.4 



The supraorbital ridges are of moderate masculine dimensions. 

 The forehead is well-arched. A slight sagittal elevation extends for 

 some distance beyond the bregma. The mastoids are of good 

 mascuhne size and ordinary form. 



1 This is probably slightly in excess of what it was originally, owing to imperfections in repair.
