dentation, to he carried forwards and inwards to the carina, meeting 

 the hinder ends of the pectoral lines. 



Anteriorly, we are enabled to see the under side of the pointed 

 manubrium, and the coracoidal beds, and gain some idea from the dis- 

 similarity of the parts on the two sides of the former, of the method 

 of decussation of the latter. 



The anterior third of the lateral margins of the body of the ster- 

 num .show also, upon this view, the little rounded elevations indicating 

 the position of the articular facets for the hccmapophyses. 



The keel fails to reach quite to the end of the sternal body behind, 

 but is brought far up in front, commencing immediately beneath the 

 manubrium.

 Natural size from the specimen. 



Owing to the decussation of the coracoidal grooves, it depends upon 

 which side of the sternum we view, as to how this part of the bone 

 appears. In the drawing the right lateral view is presented, and in 

 this particular specimen the coracoidal groove seems to have a deep 

 triangular notch in it. Had we seen it the other way, the groove 

 would appear as if it ran in one continuous belt around this anterior 

 part of the bone.
