116 SHAWANGUNK HEAD. 



vation : narrow at its posterior extremity, it widens gradually to its anterior 

 termination in the edges of the premaxillary bones. The anterior part 

 has about four times the width of the narrowest portion of the posterior. 

 The palatine fossa is not much arched, but, compared with the human, 

 approaches to a plane. On its posterior part is discerned the interpalatine 

 suture, which forms a ridge through the posterior half, and a fissure through 

 the anterior. Two pairs of foramina are visible in the posterior half, both 

 of them small and narrow, having little more than the diameter of a writing 

 quill. The distinction between the palatine and maxillary bones is not 

 visible. 



LOWER JAW. 



The lower jaw (Plate XVI.) has about the same size as that of the 

 great skeleton, and does not differ from it in any remarkable way, except, 

 as has been already indicated, that the vestiges only of tusk-sockets are 

 to be seen. The cavities are filled with osseous matter, not in a smooth 

 and even way, but so as barely to indicate the situation of the original 

 sockets on both sides.
