EAST AFRICAN MAMMALS IN NATIONAL MUSEUM. 87 
Sotik, 2 (Draper); Ulukenia Hills, 3, including one odd skull (Loring, 
Rainey). 
German East Arrica: Near head of Sironera River, western edge 
of Serengeti Plains, 6 (Clark, Lindsay). 
The series of specimens from Serengeti Plains, German East Africa, 
includes two skins and four skulls. Two of the skulls unquestionably 
belong with the skins, but as they are not matched each specimen has 
been given a separate number in the museum catalogue. Mr. Elton 
Clark records the weights of two females collected by himself at this 
locality as 24 and 29 pounds. 
The Sergenti Plains skins differ somewhat in color from the average 
run of skins of schillingsi from British East African localities, and 
approach closely in this regard specimens of Oreotragus oreotragus 
aceratos ' collected near Beira, Portuguese East Africa. The females 
from Serengeti Plains, however, have well-developed horns like 
schillingsi, and may be intermediates, connecting these two sub- 
species in general characters. 
Heller made the following manuscript notes on the type specimen 
in Berlin:
