The horns of my old buck are well developed, although no records they mea- 
sure along the front curve about 31 cm. with a basal circumference of 13'/s em., 
and a distance between the tips of 6'/2 em. 
Concerning the skull NEUMANN says that the nasals and premaxillaries of the 
typical L. walleri are much shorter than those of L. sclateri. Fortunately in this 
case he gives the dimensions of these bones in two specimens of L. walleri, and one 
L. sclateri. These measurements which are quoted below are said to be derived from 
old male skulls as also is the case with mine.

From this may be seen that my specimen occupies an intermediate position 
between L. walleri and L. sclateri with regard to these measurements as well which 
thus confirms the supposition expressed above concerning the subspecific value only 
of L. sclateri. 
For the benefit of a future comparison of other cranial dimensions as well, of 
specimens from different localities the following measurements of my adult specimens 
from Guaso Nyiri are recorded.

If Brooke’s figure of a male skull of the typical L. walleri' is correct, the 
distance between the proximal end of the premaxillary and the nasal is considerably 
greater than is the case in my specimen in which this distance is only 7 mm. which, 
of course, stands in connection with the somewhat longer premaxillary in this inter- 
mediate form. : 
The skull of the Gerenuk displays several very interesting peculiarities to which 
I will pay attention at another opportunity.
