162 BEINAR LONNBERG, MAMMALS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION ETC. 
»otter brown» tinge. The shoulders and hams are thinly overlaid with »warm 
sepia» passing into »otter brown». The ground colour of the upper neck is hoary 
grey rather thickly oyerlaid with »warm sepia» (395. 1). The face is »>warm sepia» 
(305. 2) paler and mixed with hoary grey; on the sides the forehead is »burnt 
umber» (Rép. de Couleurs, 304. 2) somewhat mixed with »warm sepia». The ears 
are the palest shade of »dark fawn» (Rép. de Couleurs, 307. 1) fading to whitish 
towards the outer margin of the basal half, but inclining to »warm sepia» on the 
upper margin and the tip, white inside. The white eye-mark is well developed, fully 
3 cm. broad and extending about 7—8 em. in front of the eye. A broad white 
band around the muffle. The chin is white beyond the angle of the mouth. The 
interramial space between the white chin and the white throat spot is whitish, tinged 
with »otter brown». The lateral angles of the white throat spot do not reach the 
base of the ears. The lower side of the neck smoke grey, the hoary grey being 
tinted with brown. Nothing white on the chest. The white rump band is about 3 
em. broad and interrupted dorsally in the middle for about 2'*/2 ecm. in one of the 
bucks. The tail is warm sepia above and on the tuft, white below. The fore legs 
below the »knee» are »warm sepia» (305.2) in front, »chocolate» (343. 2) on the sides 
and behind; the white band around the hoofs and false hoofs is narrow. The hind 
legs below the tarsal joint are »dark fawn» (307.4) in front, more blackish behind. 
The cow is generally paler, the »warm sepia» tint on the back of the buck 
being substituted by a corresponding tint of »brownish drab» (302), and the colour 
of the lower legs nearest to »raw umber» (301). 
In addition to what has been already mentioned concerning the colour of the neck 
and the breast it may be concluded from this description that the Waterbucks from 
Guaso Nyiri (Pl. XIV fig. 2) are considerably paler than the Thika race. The back 
of the latter is said to be »rétlich sepiafarbig>, but there is no reddish tint in the 
former. The Thika race has »die Kérperseiten nur ganz wenig mit grau getént», 
while there is more grey than sepia on the corresponding parts of the Guaso Nyiri 
specimens. In the Thika race »die Weichen sind heller, sehr hell umbrabraun (Rep. 
de Couleurs 301. 1 aber etwas grauer)» in the Guaso Nyiri specimens there is no trace 
of »raw umber» on the lower flanks. The ears are also much paler in the Guaso 
Nyiri race. 
It appears also to be paler than the typical South African race, which at the same 
time is considerably larger as can be seen from the cranial measurements recorded below.
