MAMMALIA. 4? 



Mr. Ogilby ("On the Generic Character of Ruminants") di- 

 vides them into two families, on the form of the muzzle : 



I. CAPRID^E. 1. Mazama (furcifer). 2. Madoqua (Saltiana). 

 3. Antilope (cervicapra). 4. Gazella (dorcas). 



II. BOVID^E. 1. Tragulus (pygmeus). 2. Sylvicapra (mer- 

 gens). 3. Tragelaphus (picta). 4. Calliope (strepsiceros). 5. 

 Kemas (goral). 6. Capricornis (Thar). 7- Bubalus (mauritani- 

 cus). 8. Oryx (capensis). Proc. Zool. Soc. 1836, 131. 



Professor Carl Sundevall (" On the Pecora of Linnaeus/' in 

 Swedish, in Kongl. Veten. Akad. Handl. 1844, published sepa- 

 rate in German in 1848) divides the Antelopes into four families, 

 according to the form of the hoofs. 



I. CAPRINE. 1. Nemorhedus. 2. Oreotragus. 



II. ANTILOPINA. 1. Antilopse Gazellae. 2. Dicranoceras. 

 3. Bubalus. 



III. BOVINA. 1. Oryx. 2. Catoblepas. 3. Anoa. 4. Por- 

 tax. 5. Damalis. 



IV. SYLVICAPRINA. 1. Hippotragus. 2. Strepsiceros. 3. 

 Cervicapra. 4. Calotragus. 5. Nanotragus. 6. Neotragus. 

 7. Sylvicapra. 8. Tragelaphus. 9. Tetraceras. 



Rafinesque names, but does not define, the following genera, 

 which appear to belong to this tribe : Antilope, Gazella, Strep- 

 siceros, Dryxis, Addax, Bubalis, and Enagrus. Anal. Nat. 56, 

 1815. 



In the Annals and Magazine of Natural History for 1847, 

 Gleanings of Knowsley Menagerie, vol. ii. 1850, and Proc. Zool. 

 Soc. 1851, 111, I proposed to divide them as they are arranged 

 in this work.
