The »Perere» as the Hyraxes are named in Kisuahili were very common near 

 Escarpment station but as they are entirely nocturnal I only saw this specimen just 

 before sunset one evening, and although I walked through the forest every evening 

 as long as I stayed there trying to obtain some more it was without success. In 

 night-time they made an awful noise, especially about 9 o'clock, and produced very 

 strong creaking and grating sounds, and now and then some ghastly screams, but 

 they were then impossible to detect among the foliage and branches of the trees. 

 We heard »Perere» as well in the forest of Kenia, and one day on an open place I 

 saw at some distance a young specimen scramble down a small tree and disappear 

 in the bushes.

Elephas africanus cavendishi Lydbkker. 



Lyderker: Proc. Zool. Soc.,. London 1907, p. 395. 



The African Elephant has during the last years been subdivided in a number 

 of subspecies. The material on which this proceeding has been based has not been 

 very rich depending upon the bulkiness and the difficulty of procuring it. It has 

 been principally the shape of the ear which has given the characteristics used for 

 the separation of the subspecies. An Elephant (PI. VI, figs 3 & 4) which I shot 

 ^^2 1911 at the waterplace called Njoro in the thornbush country north of Guaso 

 Nyiri and Chanler Falls is in this respect most similar to Lydekker's Elephas afri- 

 canus cavendishi. The type locality of this race is »the Lake Rudolph districts and 

 this stands in good correspondence with other faunistic features of the country where 

 I obtained my specimen. 



The great transverse diameter of the ear is an especially prominent characteristic 

 of E. a. cavendishi. This measurement was in Lydekker's type 87,5 cm. and in my 

 specimen somewhat jnore still viz. 100 cm. from the posterior margin to the fold at 

 the ear-opening. As can be seen on the photo (PI. VI, fig. 3) the ear-lappet is well 

 developed, but hardly so long as in the Aberdare Elephant {E. a. peeli). 



The following measurements were taken on the just dead animal: 



Distance in a straight line from anus to fold at ear-opening , 300 era. 



Distance from this fold to posterior corner of eye 52 » 



Distance from posterior corner of eye to the place where the tusk projects free from the surrounding gum . . 52 » 



Distance from the latter place to the end of the trunk 22.5 »
