CEREBELLUM OF MAMMALIA. 



!'l 



In Carnivora the smallest species (fig. 89, Stoat) have the 

 smallest lateral lobes in proportion to the middle one. 



In the Quadru- 

 mana the middle 

 lobe is proportion- 

 ally largest in 

 the Lemurida and 

 smaller Platy- 

 rhines. The ap- 

 pendicular lobule 

 is present in the 

 Aye-aye 1 and 

 other Lemur idee, 

 and is lodged in a 

 special pit of the 

 petrosal. In the 

 larger Catarhines 

 the lateral lobes 

 increase in size, 

 and lose, or incorporate, the appendix ; they show the lobular 

 groups of lamellae, especially on the under surface, fig. 62, as 



in Cetacea, and in Man. 

 The * flocculus,' fig. 64, n, to 

 which the origin of the 

 acoustic nerve can be traced, 

 is present in all Quadru- 

 mana, and is well marked in 



Base of the brain, Delpliinus Delpuis.
