8. Madoqua phillipsi. Phillips's Dik-dik. 



Six flat skins and four skulls (Nos. 3,901-3,904), the latter being 

 in the collection of the Academy of Natural Sciences of Philadel- 

 phia. 



*9. Oreotragus oreotragus ("Forst.," Sehreb.). Klippspringer Antelope. 



A mounted head and an entire skin of this antelope are in the 

 University of Pennsylvania series. 



*10. ? Kobus ellipsiprymnus (Ogilb.). Common Waterbuck. 



One mounted head in the University of Pennsylvania exhibit. 



*11. Kobus defassa (Rupp.). Defassa Waterbuck. 



A skull is in the University of Pennsylvania series. 

 •••12. Cervicapra sp. ? 



Two pairs of horns with portions of attached skulls indicate this 

 genus too imperfectly to determine the species they represent. 



13. Gazella thomsoni^ Gunth. Thomson's Gazelle. 



Two skulls of males and two skins (Nos. 3,898, 3,934, 3,935, 3,994) 

 were given the Academy of Natural Sciences of Philadelphia. The 

 skull of a young male agrees exactly with Peters' figure* of a young 

 granti which Gunther made the type of G. petersi. A comparison 

 with our series of granti and thomsoni convinces me that petersi is a 

 young thomsoni. 

 *14' Gazella soemmerringi berberana (Mtsch.). Soemmerring's Gazelle. 



Several specimens which adorn the University of Pennsylvania 

 collection belong to this race. 

 15. Lithocranius walleri (Brooke). Waller's Gazelle. 



Two skulls, male and female, (Nos. 3,896, 3,897), were presented 

 to the Academy of Natural Sciences of Philadelphia. Three male 

 heads are in the University of Pennsylvania series. 



*16. Oryx beisa (Rupp.). Beisa Antelope. 



Two mounted heads and four skulls in the University of Pennsyl- 

 vania series. 0. callotis Thos. does not seem to have been met 

 with. 

 *17. Strepsiceros strepsiceros (Pall.). Greater Kudu. 



The University of Pennsylvania contains one mounted head of 

 this species.
