Obs Having never had an opportunity of examining a perfect speci- 

 men of tliis animal, I have classed it provisionally iu the Sub-genus 

 Ai^ocerus. The description above given has been dravenup from an im- 

 perfect skin in the collection of Mr. Verreaux. Mr. Steadman has the 

 inerit of having first brought this Anlilope under the notice of the Sci-

 rewarding him for his activity and enterprize.
