that country in Thomas’s hands for examination. Besides examples of the 
two previously known Algerian species—Gazella dorcas and G. cuvieri— 
Thomas found that two other species, hitherto apparently unrecognized, were 
represented in the collection. Of one of these, which Thomas named 
G. loderi, we have treated under the head of G. leptoceros. Of the other, 
to which we now propose to refer, only a single specimen, consisting of a 
skin anda skull, was in the series. This, however, was of so entirely a 
different character from the three others above-mentioned that Thomas found 
it necessary to refer it to a new species, which he proposed to call G. rujfina, 
from its generally bright, rich rufous colour. The specimen not having been 
obtained in the field, but having been purchased at a shop in Algiers (in 
the spring of 1877), cannot have any certain locality assigned to it; but 
in all probability it was brought from somewhere in the interior, as it is 
hardly likely that such an object would have been imported into Algiers 
from a distant country.

There can be no doubt that, as stated above, Gazella rufina is most nearly 
allied to G. rufifrons of Senegal, from which, however, we have already 
stated its points of difference. Sir Edmund Loder has had a water-colour
