182 EINAR l6NN3ERG, MAMMALS COLLECTED BY THE SWEDISH ZOOLOGICAL BXl'EDITION ETC. 



The bulk of a Buffalo bull is quite amazing, and few animals give such an 

 impression of powerful strength as he does. One is therefore quite astonished to 

 see the comparative slehderness of its short leg-bones. 



In the following table of measurements a comparison can be made between 

 the dimensions of the skulls of th6 bull and the cow from Guaso Nyiri as well as 

 with the corresponding measurements of a skull of the true Buffelus caffer from 

 »Caffraria. 



Coudylobasal length . . . ■ 



Basal length 



Greatest breadth of skull across orbits . . 



Least interorbital width 



Mastoid breadth . ■ . 



Distance from orbit to tip of premaxillary 



Length of nasals 



Breadth of nasals 



Length of upper molar series 



Greatest breadth across premaxillaries . 



The latter is a little superior in most dimensions. The most striking feature 

 in the skull of my Buffalo bull is the shortness of its preorbital region. This may, 

 however, be an individual variation as the corresponding dimension of the cow is 

 longer and almost equal to that of the South African. The length of the nasals 

 stands in direct correspondence with the preorbital length generally in these specimens.. 



Orycteropus afer subsp. 



(Conf. Lydekkeb: The Game Animals of Africa. London 1908, p. 466.) 



In the neighbourhood of Nairobi Orycteropus was not uncommon, and well 

 known to the natives under the name »Manga». In consequence of its nocturnal 

 habits and because it always spends the days in its deep burrows, it is never seen, 

 and specimens can hardly ever be procured. I saw many times its scratchings and 

 diggings which sometimes may be obnoxious. The termites often make their dwellings 

 in the roads which are made of hard-packed red clay which appears firm as brick. 

 But in spite of this hardness the Manga with its powerful claws is able to break 

 up the road and make deep holes in the same to reach its favourite food, the whitfe 

 ants. One evening in Jan. 1911 I rode with Mr. Hampsojst along the road to his 

 farm and found it without fault, but the following morning when we passed the 

 same way the Manga had done lots of damage and broken up the road in several
