weil die Stellung dieser merkwiirdigen, gleichsam mehrere 
Familien verbindenden Gattung, bei der bisherigen nur 
vorliiufigen Untersuchung Trinchese’s, noch ganz unsicher 
ist.””. I will only allude here to one view implied rather than 
expressed by Mr. Garstang *. He compared a lobe of the 
pleuropodium of Hancockia with one of the four arcuate lobes 
of the “ raised curtain ” forming the pleuropodium in Loma- 
notus. ‘lhe 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 papille as their centres 
(Pl. XVII. fig. 2).

LVIII.—On two new Central-African Antelopes obtained by 
Mr. Ff. J. Jackson. By OLDFIELD THOMAS. 
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 helow, 
are these specimens absolutely the first of their respective 
forms which have been sent to Kurope, both seem to require 
new names, the one specitic and the other subspecific. 
Firstly, with regard to the Hartebeest. In 1859 Mr. Peth- 
erick sent home from the Bahr el Gazal “ several heads of 
both sexes ” of a Hartebeest referred by Dr. Gray f to Alce- 
laphus bubalis, but of which a female skull, the only remnant 
ot the series now in the British Museum, appears to belong to
