form being- a little larger. It is found among the Kourgans 

 (Fig. 50); the width is greater posteriorly, and the lateral parts 

 more convex, loph. kurganicus. 



Fig. 50.— Lophoc. Kurganicus. 



XIV. Chomatocephalus. 



I have found subgroups with the following characteristics : 



a) Chom. angulosus, because it has a surface with angular pro- 

 jections. 



b) Chom. summus, on account of its great height. 



c) Chom. cristatus, on account of its crest-like summit. 



d) Chom. sphenoidalis, for its wedge-like form as observed 

 from the norma verticalis. 



XV. Platycephalus. — The varieties with most subvarieties are 

 the Ellipsoides, the Sphenoides, and the Platycephalus. Of the 

 Platyc. I have so far been able to distinguish 22 varieties, of which 

 several also have subgroups, as the Isobathyplatycephalus, which 

 I have called siculus because first found in the tombs of the neo- 

 lithic age in Sicily (Fig. 51). We find: 



a) Platyc. cuneatus ; b) platyc. humilus ; c) stenometopus ; d) 

 platyc. brachymetopus ; e) euryplatymetopus ; f ) platyc. embolicus ; 

 g) platyc. rotundus ; h) platyc. scalenus, and so on.
