of the type locality of t hikes. The Juja Farm skin is much lighter 

 than the type but agrees well in color with adults from Juja Farm. 

 Several skins from Juja Farm and the Northern Guaso Nyiro are 

 in the National Museum and all are conspicuously lighter than the 

 Taveta skin. A mounted specimen, an older male but still somewhat 

 immature, from Taveta is in the Museum. The horns of this 

 specimen are 19 inches in length. The coloration is much lighter than 

 that of the type owing to its exposure to light for a long period, ap- 

 proximately twenty years. It is surprising how little individual 

 variation in color is shown in a series of thikce from Juja Farm near 

 Nairobi. Specimens from the Northern Guaso Nyiro and from 

 Mtoto Andei agree with these in tone of coloration. The dimensions 

 of the adult skull No. 39693 from Taveta are: condylo-basal length, 

 350; greatest breadth, 156; nasals 143x41; diameter of orbit, 50; 

 orbit to gnathion, 220; length of premaxillse, 116; upper tooth row, 

 109 ; PM 1 to gnathion, 107 ; width of palate across M\ 85 ; age, last 

 milk molar still in use, and last molar just erupted. 



Among the Swahili tribes of the coast district the waterbuck is 

 known as kuru.
