5899. The base of the skull, with the atlas, of an Englishman, showing the same 

 excessive development of the left paroccipital, with its articular surface for the 

 corresponding part of the atlas, as in the skull of the Native of the Philippine 

 Islands (No. 5531). The paroccipital forms a distinct tubercle upon the 

 right side. 



The paroccipital is, in many skulls, reduced to a mere " scabrous ridge extended from the 

 middle of the condyle towards the root of the mastoid process " (Monro, On the Bones, 8vo, 

 1820, p. 72), the "eminentia aspera musculum rectum lateralem excipiens" of Soemmer- 

 ring (De corporis human} fabrica, t. i.). The knowledge of its general homology as the di- 

 apophysis of the occipital vertebra renders intelligible its occasional development into a pro- 

 cess equalling the mastoid in length, and repeating the proportions which it most commonly 

 presents in the inferior mammalia, where it often takes the place of the true mastoid, which 

 in them is suppressed.

5900. The cranium of a Negress, of the elongate narrow type, with the nasals flat- 

 tened and the upper jaw produced. 



This is chiefly remarkable for the mal-directed growth of the right upper canine, which 

 projects upwards, forwards and inwards into the right nostril. 



Hunterian. 



5901. The calvarium of a skull, with the short, broad, rounded type of cranium, 

 showing obliteration of the left half of the coronal suture. Hunterian. 



5902. A cranium, said to be from Madagascar, but with all the characters of the 

 European or English skull. 



The molar teeth are small, and much worn. As an individual peculiarity, it exhibits an 

 almost symmetrical pair of smooth hemispheric tubercles on the basioccipital. 



Hunterian. 



5903. A mutilated cranium which has been subjected to the action of fire, showing 

 the peculiarity of a complete anchylosis of the condyles and basilar part of the 

 occipital, with the corresponding part of the atlas. 



The fractured basis of the paroccipitals indicates them to have been unusually developed. 

 The alisphenoid largely articulates with the parietals on both sides : the glabella is little 

 prominent ; and the superorbital ridges are thin and well defined. The molar teeth would 

 appear, from the sockets, to have presented the ordinary European proportions and mode
