A CLINICAL STUDY OF THE SKULL. 55 



long by 1 wide), which lies between the tnber and the lambdoidal 

 suture. In No. 1562, of the same race, an elevation extends from 

 the tuber to the sagittal suture. It limits the inclination of the 

 parietal bone towards the occiput. 



The temporo-Jrnntal eminence. — Under this head may be men- 

 tioned a swelling which is felt occasionally in the living subject 

 directly to the outside of the temporal ridge as it is defined on the 

 frontal bone. It forms a low obtuse prominence, measuring about 

 3 centimetres in diameter. It is best discerned in young iudi- 

 viduals, since in adults it is obscured by the massive temporal 

 muscle. I have found the temporo-froutal eminence, so frequently 

 in Peruvian crania that it may be included among the characters 

 distinguishing them. In a Marquesas skull, in the A. N. S., a 

 similar prominence is marked. 



The depressions which can be detected on the vertex are arranged 

 as follows : In advance of the bregma ; this constitutes the pre-hreg- 

 mal. At the centre of the fontanel, or embracing in a general 

 way the region of the fontanel ; this is the bregmal. At the line 

 of the coronal suture and the part directly back of it ; this is the 

 coronal. At the broad interspace between the frontal bone and the 

 tubera ; this is the post-coronal, and appears to be an extension of 

 the foreo-oing. An apparent depression is defined at the obelion. 



The coronal depression has been described by Prof J. Cleland 

 (Philosoph. Trans., vol. clx, 1870). It can be easily defined in the 

 living subject. Abundant means are at hand for confirmation of 

 this statement. Children exhibit the peculiarity as well as adults. 

 It is generally seen in short high heads, which also retain a short 

 sagittal suture and an abrupt curve to the mid-vertex. Rolleston 

 (British Barrows, 1877) names skulls which show this peculiarity 

 "cut off;" it appears to be the same variety as is described by 

 Lissauer (Archiv. f. Anthropolpgie, 1885, p. 9) under the name of 

 " sagittal Kriimmung," 



When the two coronal depressions are associated with large tu-
