him during the expedition, and now in the British Museum, are evidently 
referable here. Mr. W. L. Sclater has also catalogued four heads in the 
Calcutta Museum, obtained by Mr. Blanford on the same occasion, as 
G. isabella. Mr. Blanford gives us the following field-notes on the present 
species :— 
“So far as my observation extends, neither this nor Bennett’s Gazelle are ever seen 
in large flocks, like the animals of the Springbok group. Usually both are seen solitary 
or in parties of from two to five together, inhabiting thin bushes, generally on broken 
ground. They feed much upon the leaves of bushes. The male has a peculiar habit 
when surprised of standing still and uttering a short sharp cry. Like most Antelopes, 
they keep much to the neighbourhood of some particular spot. After long observation, 
I am convinced that Bennett’s Gazelle never drinks, and all that I could ascertain of 
the present Gazelle leads to the same conclusion in its case.” 
In our efforts to obtain further information about the Isabella Gazelle, we 
did not fail to apply to the officers of the Anglo-Egyptian garrison at 
Suakin for a set of specimens of it for the National Collection. In reply to 
our requests Major Sparkes, Surgeon-Capt. Fleming, and Lieut. Carleton were 
kind enough to send to the British Museum five examples of it; but we 
cannot say that the examination of these specimens has enabled us altogether 
to understand this very difficult species. Of the five examples from that 
locality, three have and two have not a black nasal patch, while the dark 
lateral band in some is fairly distinct and in others almost obsolete. It is 
thus evident that these characters, of systematic importance elsewhere, are 
not, in G. zsabella, even of local constancy. 
Among the Gazelles registered in the Zoological Society’s ‘ List of Animals’ 
(1896) as received during the past twelve years there have been several 
which, doubtless, should have been referred to the present species, but have 
been entered under Gazella dorcas. Amongst these may be specified an 
example presented by Commander W. Crofton, R.N., in July 1890 (speci- 
men ¢), a female presented by Col. Holled Smith, C.B., in July 1892 
(specimen g), and a pair (A, 2) received on deposit in May 1894. 
After the arrival of these specimens from Suakin, Mr. A. Thomson, the 
Head-Keeper, called Sclater’s attention to their differences from the ordinary 
G. dorcas. They were of a more reddish colour, and had a broad and some- 
what distinct side-stripe and a blackish nasal spot, in addition to other 
smaller differences.
