luian boue, olbers two smaller lateral ones, and others mere 

 traces of thesie bones. 



The skull from Gran Canaria presents some slight 

 difierences from the others. It is thicker and heavier, the 

 eyebrows more prominent, the eye sockets with a tendency 

 to squareness; the chin is very pointed ; the Wormian bones 

 are small, the muscular impressions are strongly marked ; the 

 teeth are more irregular than in the specimens from Ten- 

 eriffe. On the whole this skull has one of the best developed 

 foreheads, and the brain-case is Avide aboA^e.* 



One of the TenerifFe skulls has three cervical vertebrae 

 attached, showing it to have belonged to a mummy. 



The following are the measurements of the several skulls 

 in centimetres, the length being taken from the base of the 

 frontal bone to the occiput, and the breadth being that 

 between the most prominent parts of the parietal bones. 



The cephalic indices and averages are as folloAvs. — 



Index often TenerifFe skulls , . . . '764 



Index of one Canarian skull . . . '758 



Average length often Teneriffe skulls 18'30 cm. 



Average breadth of the same. . . . 1400 



* In the history of the islands, the inhabitants of Gran Canaria would 

 seem to have excelled those of the other islands in energy and military 

 prowess.
