in which the suture was convex, inasmuch as this convexity is most 

 marked in, if not confined to, the mesal part of the suture. (See 

 infra.) 



THE EMINENCES AND DEPRESSIONS OF THE VERTEX. 



The eminences of the vertex which have been separately named 

 are the frontal, the parietal or the tuberal, and the occipital. In 

 addition, I venture to name five others, as follows : 



The meso-coronal. 

 The metopic. 

 The para- tuberal. 

 The meso-lambdoidal. 



The meso-coromd emlnenee, lies on the frontal bone just in 

 advance of the meso-coronal portion of the suture, about two 

 centimetres above the stephanion. It may involve the suture 

 itself, when thov corresponding part of the parietal bone is also 

 elevated. It is marked in many Peruvian crania, but is often 

 absent in the skulls of Negroes and Esquimaux. 



The metopic eminence is a median elevation of the frontal bone 

 over the interfrontal suture. It is inconstant, but may amount to 

 a conspicuous carinatiou which can be seen often in the living 

 individual. 



The para-taberal eminence is a rounded elevation which lies be- 

 tween the parietal tuber at its posterior limit and the obelion. It 

 is commonly present. It is least developed in the Esquimaux. 



The meso-lambdoidal eminence lies on the parietal bone in advance 

 of the lambdoidal suture at its middle portion, or it may cross the 

 suture and involve the occiput. It is marked in synostotic crauia 

 of the criminal type. It is very well seen in a skull of a Krhn.^ 

 In some crania it appears to be continuous with the tubera. 



In No. 1561, Esquimaux (A.. N. S.), the vertex is marked by a 

 large adventitious but distinct swelling (measuring 2 centimetres
