LÖNNBERG, MAMMALS FROM BRIT. E. AFRICA. 29 



tbe back the present species resembles P. (D.) stuhlmanni 

 Matschie from Bukoba. Tbe latter appears, however, to 

 be a mucb larger animal with the distance from tip of na- 

 sals to the occiput 92 mm., diastema 15 mm., length of up- 

 per molar series 34 — 35 mm. etc. These measurements and 

 other outer differences together with the widely different 

 geographical origin, with several other Hyraxes inhabiting 

 the intervening area, prohibit an identification with the Tree- 

 Hyrax from Donya Sabuk which thus appears to be a quite 

 distinct form. From P. (D.) bettoni Thomas & Schwann it 

 differs in colour as the former has chocolate-brown hairs 

 with påle drab, subterminal rings and black tips. In addi- 

 tion to this the dorsal spöt of P. bettoni is »small, oval», 

 and its hairs påle yellowish white, and »hands and feet påle 

 buffy.»^ 



Nesotragus moscliatus Duben. 



1 head-skin and skull of a buck presumably from Donya 

 Sabuk. 



The condylobasal length of this skull is 112 mm. This 

 dimension varies in the material of male Sunis in this mu- 

 seum from 108 to 118 mm., both extremes being adult bucks 

 from the Nairobi forest. 



Heller has distinguished the Suni of the Kenia-district 

 and the Aberdare Range as a separate subspecies which he 

 has named akeleyi. This is said to be darker than the ty- 

 pical N. moschatus »the white of the throat sepa- 

 rated medially for half its length by a fulvous band; legs 



darker with black pasterns and stripe in front to knee». 



Regarding these characteristics it must be remarked that 

 the general colour is very variable as T have already pointed 

 out before," some specimens from one and the same locality 

 being »more reddish» others »dark, chestnut brown». Black 

 or blackish pasterns are to be seen in von Duben's type- 

 specimens as well as in specimens from Kilimanjaro, Kenia, 

 and Meru boma. The dark stripe in front of the fore-legs 

 is more or less developed, but may also be traced in von 

 Duben's types. Perhaps the white of the throat is not so
