considerable size, and especially the breadth, of the anterior 

 part of the hemispheres. As in the Musk-Deer and the 

 Pudu, the cephalic prolongation of the calcarine suleus 

 appears on the dorsal surface of the hemisphere. The 

 brain is not unlike that of the Muntjac, but the sulci are 

 better developed in Michie's Deer, and the anterior part- 

 of the hemispheres are broader in the latter (Garrod).

D. 434. The brain of a Sambur (Cervus aristotelis). 



This is a typical Deer's brain; it is larger and corre- 

 spondingly more complicated than the brain of Michi' 

 Deer. 



There is a long vertical " pseudosylvian sulcus." Eeio- 



lateral and entolateral sulci are present. 0. C. 1328 E //.

D. 437. The brain of a new-born Axis (Cervus axis). 



The extraordinary richness of sulci in this brain is very 

 remarkable, when its small size is taken into account. 



This is especially noteworthy in the region of the lateral 

 sulcus, where also well-developed ecto- and entolateral sulei 

 are found. 0. C. 13:.'
