5363. The skull of a male African Negro. 



A larger proportion of the alisphenoid joins the parietal than is commonly seen in the 

 Australian skulls. The frontal prominences and glabella project, but do not form a con- 

 tinuous thick produced ridge, as in the Australian race. The frontal part of the cranium is 

 narrow. The jaws are produced. The molar teeth are large. The paroccipitals are well 

 developed.

5364. The skull of a male Negro, from the Gold Coast, Africa. 



The cranium is large and expanded at the parietal protuberances, though narrow at the 

 forehead. The nasal bones are broad and flat, but are continued from the same vertical line 

 as the glabella. The alisphenoids articulate largely with the parietals. The traces of the 

 maxillo-premaxillary suture may be followed to near the interspace between the outer incisors 

 and canines. The jaws are produced. The molars are not larger than in the White races. 



Hunterian. 



5365. The cranium of a Negress, eighteen years of age, born in the island of Jamaica. 



The last molar is in place : the sagittal suture is obliterated, and the stylohyals are anchy- 

 losed. The eustachian processes are well developed. This skull presents the shorter and 

 broader type of the African crania. The slightly prominent nasals are continued from the 

 same line with the glabella. The alisphenoid articulates with the parietal on both sides of 

 the head. The maxilla is very prominent, and the suborbital depressions strongly marked. 

 The calvarium has been detached, showing that the walls of the cranium are of moderate 

 thickness, with the usual development of diploe.

5366. The cranium of a male African Negro slave, who died an idiot in the Hospital 

 at Demerara. 



The skull presents the same general shape as that of the Negro from the Gold Coast 

 (No. 5364), being broad at the parietal regions, and with the sides less sloping from the 

 middle or sagittal line ; but the superorbital ridges and glabellse are almost as prominent, as 

 in the Australian skulls. The upper jaw, also, is as much produced and the bony palate is 

 as long and as broad as in most Australian skulls, but the molar teeth present a marked infe- 

 riority of size. The alisphenoid joins the parietal on both sides of the head. The super- 

 occipital region is concave between the occipital spine and the foramen magnum, and this 

 concavity is bounded by two lateral ridges which are unusually developed. The paroccipital 

 tubercles are well marked and the mastoids unusually large and rugged. The calvarium has 

 been removed, showing the characteristic thickness of the cranial parietes. The posterior and 

 anterior clinoid processes are united, forming a bony bridge over each side of the deep sella 

 turcica. The frontal sinuses rise high above the orbit on the right side.
