NERVOUS SYSTEM. VERTEBRATA. 335 



sulcus is not joined to the coronal, and its connection with 

 the large, irregular, triradiate, diagonal sulcus is very 

 doubtful. 



The splenial complex is wholly mesial in position and is 

 not connected with any crucial-like sulcus. 



The cerebellum is of the usual transversely foliate 

 Ungulate type. 0. C. 1328 D a.

D. 459. The brain of a Duikerbok (Ceplialoplius monticola). 



This brain is remarkable by reason of its exceeding 

 abundance of sulci, in spite of the fact that it is of small 

 size, Although the brain is smaller than that of Hydropotes, 

 it exhibits a wealth of sulci as rich as that of the much 

 larger Odocoileus. 



In proportion to the size of the animal this brain is large. 



The plan of its cerebral sulci and the features of the 

 cerebellum resemble those of the Deer Family.
