setter brown » tinge. The shoulders and hams are thinly overlaid with !>wartn 

 sepias 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 » (Rep. de Couleurs, 304. 2) somewhat mixed with »warm sepia». The ears 

 are the palest shade of »dark fawn» (Rep. 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 cm. in front of the eye. A broad white 

 band around the muffle. The chin is white Iseyond the angle of the mouth. The 

 interramial space between the white chin and the white throat spot is whitish, tinged 

 with setter 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 

 cm. broad and interrupted dorsally in the middle for about 2 Va cm. 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 (PI. XIV fig. 2) are considerably paler than the Thika race. The back 

 of the latter is said to be *r6tlich sepiafarbig*, but there is no reddish tint in the 

 former. The Thika race has »die Korperseiten nur ganz wenig mit grau getont*, 

 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.
