 expressed by ]\lr. Garstang *. lie compared a lobe of the 

 pleuropodium of llancochia with one of the four arcuate lobes 

 of the " raised curtain " forming the pleuropodium in Loma- 

 notus. The side view which I give of the latter genus shows 

 that the lobes are distinct and that the breaks occur between 

 the segments having the large dorsal papillae as their centres 

 (PhXVII. tig. 2).

LVIIL — On two neiv Central- African Antelopes obtained hy

By the kindness of Messrs. Rowland Ward and Co., of 

 Piccadilly, I have been entrusted with the examination of the 

 skulls and scalps of two antelopes, a Hartebeest and a Wilde- 

 beest, sent home by the well-known explorer and naturalist 

 Mr. F. J. Jackson. 



Although probably in neither case, as will be seen below, 

 are these specimens absolutely the first of their respective 

 forms which have been sent to Europe, both seem to require 

 new names, the one specilic and the other subspecific. 



Firstly, with regard to the Hartebeest. In 1859 Mr. Petli- 

 erick sent home from the Bahr el Gazal " several heads of 

 both sexes " of a Hartebeest referred by Dr. Gray t to Alce- 

 laphus bubalis, but of which a female skull, the only remnant 

 of the series now in the British Museum, appears to belong to
