agrees with this species, and has the peculiar distribution of its hair ; 
hence its name : hut he says, it has “ a long open suborbital slit, and 
small black brushes on the knees;” but this I suspect must be a 
mistake, as he himself observes no lachrymal cavity was found in the 
skull. He might have mistaken the tuft of hair for the gland at the 
distance at which he saw the specimens. He also (G. A. K. iv. 221) 
described a specimen which was in Exeter Change, which he regarded 
as the Gambian Antelope of Pennant, and calls A. forfex. His cha¬ 
racters agree in most particulars with this species, but he says it had 
“a long lachrymal sinus, and had small brushes on the knees.” If 
there was not some mistake in transcribing these descriptions, both 
these animals should be Gazellas, but I have never seen any which 
agreed with them. 
The young male in the British Museum shows the development of 
the horns of these animals. The upper rings of the growing horn fall 
olf in large thick flakes as the horn increases in size beneath: this 
explains how the extent of the smooth tapering part of the horns in¬ 
creases in length as the horn grows, and how the number of rings are 
found to be nearly the same in the various ages, and different indi¬ 
viduals of the various species. Mr. Whitfield informs me that the 
scrotum is rarely developed or dependent externally in different kinds 
of Antelopes before they have completed their first year. 
** Horns elongate , recurved at the tip ; tail slender , end tufted.
