D. 479. A cast of the cranial cavity of the Harnessed Antelope 

 (Limnotragus spekii). 



D. 480. The brain of a Kudu (Strepsiceros kudu). 



This may be regarded as an exceedingly complicated 

 Guib's brain. The dorsally-placed suprasylvian sulcus i< 

 exceedingly well developed, and on the left side has a \vrv 

 large posterior vertical ramus. It joins the coronal and, on 

 the right side, the crucial-like prolongations of the inter- 

 calary. There is a well-developed ectosylvian arc, with 

 several radiating branches. 0. C. 1327 c 



D.481. The brain of an Eland (Taurotragus oryx), ( $ ). 



In most respects this brain resembles that of the Kudu, 

 but is larger and more complicated. The branches of the 

 ectosylvian are prolonged to form a great horizontal sulcus 

 parallel to the suprasylvian. 



Behind the " Sylvian fissure " there is a deep sulcus 

 cutting obliquely into the posterior operculum from the 

 rhinal fissure. It is probably a representative of the feline 

 pseudosylvian sulcus. 0. C. 1327 Gg. 



D. 482. Cast of the cranial cavity of a Takin (Dudorcas). 



D. 483. The right cerebral hemisphere of a Goat (Copra ldr< 

 partially dissected. 



There is a large vertical "Sylvian fissure" extending 

 upward from a long horizontal sulcus the conjoint anterior 

 and posterior terminal sulci which runs parallel to and 

 some distance to the dorsal side of the rhinal fi.-.-un 1 . Tin- 

 orbital (prcsylvian) sulcus is quite independent of tin- 

 anterior terminal sulcus. These terminal sulci are analogous 

 to the ectosylvian sulci of the Carnivora. 



There is a typically Ungulate suprasylvian sulcus, with 

 long horizontal and short vertical rami. It is not joiiu i ! 

 to the well-developed diagonal sulcus, but is connected with
