of Oryx beisa, as well as the still more distinct Oryx leucoryz of Arabia, 
as subspecies of the South African Oryx gazella, but this view is not 
in accord with the intergradation theory of subspecies, not even 
with the extreme theory of ‘‘intergradation by characters.”’ The 
inclusion of these species within the limited genus Oryx would seem 
to show their relationship sufficiently without actually implying 
direct intergradation.

Concerning these specimens of the oryx, Hoffman Philip has 
written to the Museum as follows: 
These specimens were shot February 27, 1910, about 8 miles from the camp of Ella 
Bella, on the Assabot road, between Adis Ababa and Dire Dawa (between 9° and 10° 
north latitude, 41° and 42° longitude). The oryx, with a band of about five others, 
were sighted in a depression between two summits (probably a spur of the Obora 
Mountains), at an altitude of about 4000 feet. A fresh track of a greater Kudu was 
seen near the same place. This band of oryx apparently ranged over these hills at 
an altitude of from, perhaps, 4000 to 5500 feet, during the dry season. They are 
very shy and are frequently hunted by the natives. They walked in a single file 
when not alarmed. The shots were taken at very long range, part of the band having 
congregated in the shade of a large thorn tree. The hill was steep, rocky, and bare, 
except for occasional groups of thorn trees and thickets of thorn bushes; dried grass 
was plentiful, however. A Wart Hog was seen on one of the hills near by. The 
oryx displayed great pluck and tenacity of life—the male, though shot through the 
lungs and with both legs broken at the knees by another shot, made a determined 
leap with the hind legs when approached, a vicious lunge of the horns barely missing 
the writer.
