other affinities with the Hystricomorpha, but iu 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. Tlie 

 Lagomorpha, on 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 appi'oach one 

 another in their myology. 



2. That the Hystricomorpha similarly approach the Lagomorpha. 



3. That the Bathyerginie in many respects resemble the Hystri- 

 comorpha. 



4. That Bhizomys more closely resembles the MuridaB than the 

 Bathyerginaj. 



5. That the Dipodidae 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 Oscau Neumann '. 



[Beceivcd 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, TJssoga, and Kavirondo, belonging to the genus Adenota, 

 Gray. This Antelope seemed to me to be different from Adenoia 

 Icob, with which it had hitherto been united. Not having enough 

 material of the true West-African Adenota Icob 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. Decle from Uganda, and by Captain Lugard from the Niger. 

 I propose to name this species, in honour of Mr. Thomas,
