164 BINAB LONNBBRG, MAMMALS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION ETC. 



Waterbucks were seen near Lekiundu river, and on both sides of Guaso Nyiri 

 from the ford on the Marsabit road to some distance below Chanler Falls. Often 

 5 to 8 or more cows and immature animals were seen together but no buck. At 

 other opportunities single bucks, or a few bucks in company were observed or a 

 buck with some few cows. They were always found near the river, but often on very 

 bad and stony ground. They Avere not very shy. When first observed close to the 

 river they usually took their refuge to higher ground and trotted up on stony hills with 

 great dexterity. The grey fur harmonized completely with the grey, leaf-less bush 

 but they were, of course, very easily seen as they did not try to hide and their 

 contour-lines always betrayed them. They have a more deer-like and stately carriage 

 than any other antelope, because they hold head and neck high. 



Redunca sp. 



At two different opportunities not far from Nairobi I saw a Reedbuck, but it 

 was on private ground where I had no right to shoot, so that I could not ascertain 

 which species it represented.

In the thornbush country north of Guaso Nyiri I collected the material of 

 Impala Antelopes which I was entitled to by my licence viz. 4 specimens and selected 

 two good bucks (PI. XIV fig. 3), a young buck with still almost straight horns (PI. 

 XIV fig. 4) (m^ not yet up), and a female. When I had come home and compared 

 my material with specimens from Kilimanjaro (collected by Sjostedt) which must 

 be regarded as representing ^. m. suara Matschie I found that the difference in 

 colour is quite conspicuous. My specimens are irrespective of age and sex alike and 

 much darker than the Kilimanjaro specimens which display a much redder general 

 colouring. 



The general colour of the back of the Guaso Nyiri race is »fawn» (Rep. de 

 Couleurs 308. 4 in S, 308. 3 in ?), and darkens in the bucks on the posterior back to 

 »madder brown » (Rep. de Coul. 334.4). In contrast to this the colour of the Kili- 

 manjaro specimens is the same shade as »dead leafs (Rep. de Coul. 321. 3 & 4) but 

 brighter. The line of demarcation in the Guaso Nyiri specimens is quite sharp, and the 

 colour of the sides is »dark fawn» (Rep. de Col. 307. 1), while the colour of correspon- 

 ding parts in the Kilimanjaro specimens is »buff » (Rep. de Coul. 309. 1). The white 

 above the eye, on the chin and throat is similar in both races. Below and in front 

 of the eye, below the continuation of the white eyebrow-stripe there is in the Guaso 

 Nyiri specimens a blackish, not sharply defined but well visible patch which I have 

 not seen in a buck from Kilimanjaro, but which may be faintly traced in a ewe from the 

 same place. (The authors of the »Book of Antelopes* say that this patch » is never 

 present in northern » specimens, and it may thus be of some importance.) The black
