except the elongation of its 

 anterior part. 



At the anterior extremity is 

 remarked a small notch, which 

 indicates probably the separa- 

 tion of these bones in the 

 young subject. 



At the origin of this elon- 

 gation is found a protube- 

 rance considerably elevated, 

 which, increasing in volume 

 downwards, forms with the 

 neighbouring one, two large 

 eminences, between which is 

 a canal corresponding to what 

 anatomists call the symphysis 

 in man. 



It continues increasing suc- 

 cessively in volume as far as 

 (S*), where begins (he inferior 

 border called base, which is 

 at least a foot long. 



The two apophyses, viz. : 

 the coronoid and the con- 

 dyle are to be observed, with 

 the angle of the jaw. 



The superior border of this 

 jaw is very thick in front of 

 the coronoid apophysis; where 



mams in our specimen, as 

 represented in the plate at (a) 

 Fig. 1. and 2. 



The anterior extremity be- 

 ing destroyed in the specimen 

 from, Georgia, this notch 

 could not be observed. 



Part of this protuberance 

 may be observed at (b) cor- 

 responding in situation with 

 those represented in the figure 

 of M. Bru. The canal of the 

 symphysis is well preserved, 

 and very apparent in our 

 specimen. 



This part is broken off in 

 our specimen ; but from the 

 depth and direction of the 

 sockets, it is very evident 

 however, that something simi- 

 lar to this must have existed. 

 Part of the base remains at 

 (c) with the border entire. 



These parts are entirely 

 broken off in the specimen 

 from Creorgia. 



Our specimen agrees with 

 this description in all points, 

 except the inclination of the
