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 secreams, 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 sceramble down a small tree and disappear 
in the bushes.

Elephas africanus cavendishi LYDEKKER. | 
LYDEKKER: Proc. Zool. Soc., London 1907, p. 393. 
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 (Pl. VI, figs 3 & 4) which I shot 
'2/2 1911 at the waterplace called Njoro in the thornbush country north of Guaso 
Nyiri and Chanler Falls is in this respect most similar to LYDEKKEER's Hlephas afri- 
canus cavendishi. The type locality of this race is »the Lake Rudolph districet> and 
this stands in good correspondence with other faunistic features of the country where 
I obtaimed 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 more still viz. 100 cm. from the posterior margin to the fold at 
the ear-opening. As can be seen on the photo (Pl. VI, fig. 3) the ear-lappet is well 
developed, but hardly so long as in the Aberdare Elephant (Z. a. peeli). 
The following measurements were taken on the just dead animal:
