The brain is 119 mm. in total length, of which 10-4 mm. 

 represent the length of the cerebral hemispheres. Its breadth 

 is 91 mm., and height 58 mm. It is thus distinctly small when 

 compared with the size of the animal. 



The olfactory bulbs are not present, and there is a wide saw- 

 cut aci-oss the frontal region ; otherwise it is in excellent 

 condition. It has been preserved in formalin for twelve months.

The optic lobes are completely concealed and the projecting 

 occipital poles of the hemisphere rest on the anterior aspect of 

 the cerebellum, Avhich is sloped to receive them. 



The hemispheres are well fissured, the sulci being deep and 

 complicated and almost all of them having numerous hidden sulci 

 on their walls which run from the surface perpendicularly inwards 

 to the floor of the main fissure.
