other affinities with the Hystricomorpha, but in which the union 
took place. 
Other facts which may perhaps be of interest to the systematist 
are borne out by the foregoing lists. It is quite evident that 
the myology of the Myomorpha resembles that of the Sciuro- 
morpha much more closely than that of the Hystricomorpha. The 
Lagomorpha, en the other hand, in their myology are much more 
closely allied to the Hystricomorpha than to the Myomorpha or 
Sciuromorpha, and of the two latter are nearest the Sciuromorpha. 
These conclusions I believe are already recognized by systematists 
from a study of other parts than muscles; and the fact that 
myology bears out these conclusions is to my mind an important 
plea for the value of the study of muscles as a help to settling the 
position of animals. 
The results of this and the preceding paper may be briefly 
summed up in the following propositions :— 
1. That the Myomorpha and Sciuromorpha approach one 
another in their myology. 
2. That the Hystricomorpha similarly approach the Lagomorpha. 
3. That the Bathyergine in many respects resemble the Hystri- 
comorpha. 
4. That Rhizomys more closely resembles the Muride than the 
Bathyergine. 
5. That the Dipodide are more nearly allied to the Myomorpha 
than to the Hystricomorpha. 
6. That in Rodents certain muscles are valuable for classificatory 
purposes and, if several are taken, are not likely to mislead. 
7. That the muscles of the trunk, neck, and shoulder-girdle are 
the most reliable. 
5. Description of a new Species of Antelope from East 
Africa. By Oscar Neumann’. 
[Received January 1, 1896.] 
Among the animals collected during my expedition to East and 
Central Africa, in 1892-95, there are examples of an Antelope from 
Uganda, Ussoga, and Kavirondo, belonging to the genus Adenota, 
Gray. _ This Antelope seemed to me to be different from Adenota 
kob, with which it had hitherto been united. Not having enough 
material of the true West-African Adenota kob in Berlin, I took 
two horns and one skin of this species with me to compare them 
in Paris with Buffon’s type and also with specimens in London. 
In both places I found my opinion confirmed; I also found that 
both Mr. Thomas and M. de Poussarges had independently arrived 
at the same conclusion—thanks to additional material brought by 
Mr. Décle from Uganda, and by Captain Lugard from the Niger. 
I propose to name this species, in honour of Mr. Thomas, ~
