2. Description of a new Zebra. 

 By the Hon. Walter Rothschild, Ph.D.^ F.Z.S. 



[Received June 19, 1906.] 



Equus annectens, sp. nov. 



This very distinct form of Zebra is at once distinguishable by 

 the very narrow white stripes and broad black bands extending 

 from behind the ears to the root of taih Tlie black bands 

 extend from root of tail much further longitudinally towards 

 the shoulder than in any other form, all being joined up with 

 the transverse bands, and not broken up as in most forms of 

 E. hicrchelli. It differs at first sight from E, zebra and most forms 

 of E. hurchelli by the entire absence of red on the face and 

 muzzle, thus approaching E. hurchelli selousi. Head, legs, and 

 tail evenly banded with narrow white bands on an intense black 

 ground. Ears strongly banded. 



Skull. — This shows, from its less bombiform frontal aiid 

 greater width across the palate, an intermediate character between 

 the forms of Equus hurchelli and Equus zehra ; a very distinct 

 feature is the great breadth and convexity of the malar and 

 maxillary. 



Habitat. Neighbourhood of Fort Jameson, JST.E. Rhodesia. 



3. Description of a new Bush-Buck. 

 By the Hon. Walter Eothschild, Ph.D., F.Z.S. 



[Received June 19, 1906.] 

 Cephalophus robertsi, sp. nov. (Male type.) 



This is nearest to C. harveyi, C. castaneus, C. callipygu,s, and 

 C. natalensis, but difiers from them all by being quite uniform 

 in colour, of an orange-chestnut of a much paler, yellower, and 

 brighter shade.
