1899. Oribia LypEKKER, Great and Small Game Africa, p. xi (pro Ourebia.) 
All of the forms of the oribi which have been described from East 
Africa are represented in the National Museum collection, with the 
exception of Ourebia gallarum Blaine‘ from Lake Helene, east of the 
headwaters of the Omo River, 60 miles south of Addis Ababa, 
Abyssinia. The validity of this species has, however, been ques- 
tioned by Roosevelt and Heller.

Specimens.—Two, as follows: 
Supan: Mongalla Province, 120 miles east of Lado, 1 (Smith); 
Mongalla Province, 190 miles east of Lado, 5° 20’ N., 34° 30’ E., 1

Plates 34, 35. 
1910. Ourebia montana RoosEevett, African Game Trails, Amer. ed., p. 475; 
London ed., p. 487. (Not of Cretzschmar. ) 
1912. Ourebia montana xquatoria HELLER, Smithsonian Misc. Coll., vol. 60, 
No. 8, p. 12. November 2. (Rhino Camp, Lado Enclave; type in 
U.S. National Museum.) 
1914. Ourebia montana xquatoria ROOSEVELT AND He ter, Life-Hist. African 
Game Anim., vol. 2, p. 558. (Part.) 
Specimens.—Fourteen, from the following localities: 
Lavo: Rhino Camp, 11, including two odd skulls (T. Roosevelt, 
Mearns, Heller). 
Ucanpa: Nimule, 3 (Mearns, T. Roosevelt). 
The Nimule specimens, while somewhat intermediate in characters 
between true montana and xquatoria, go best with the specimens 
from Rhino Camp, on the west bank of the Nile. The Nile Valley 
form, as thus restricted, is not sharply marked from either 0. montana 
montana or O. m. cottoni, and unquestionably intergrades directly 
with both.
