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 Sciuromorpha much more closely than that of the Hystricomorpha. The 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 m y 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 Bathyerginae in many respects resemble the Hystricomorpha. 4. That Rhizomys more closely resembles the Muridae than the Bathyerginae. 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 OSCAR N E U M A N N \ [Received January 1, 1896.] Among the animals collected during my expedition to East and Central Africa, hi 1892-95, there are examples of an Antelope from Uganda, Ussoga, and Kavirondo, belonging to the genus Adenota, Gray. _ This Antelope seemed to m e to be different from Adenota 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 m e to compare them in Paris with Buffon's type and also with specimens in London. In both places I found m y 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 M r . Thomas, -'•" - - ? Communicated by the Secretary* •-....'. :.".'..'•• |
