The long-snouted dikdiks are well represented in the collection; 
but the museum does not contain specimens of three forms described 
from the area covered by this report. These include the typical 
races of each of the species, Rhynchotragus kirkii (Giinther)! described 
from Brava, Italian Somaliland; and Rhynchotragus guentherr 
(Thomas)? from central Ogaden, Abyssinia; as well as a form, prob- 
ably a subspecies of kirkii, described by Neumann from Tisso (Kwa 
Meda), North Ugogo, German East Africa, as Rhynchotragus thomas.
