Var. With a large black rhombic spot on the back of the head be- 
hind the ears. Female in Brit. Mus. 
Inhabits S. Africa, in marshy places. Brit. Mus. 
Afzelius, Lichtenstein, H. Smith and Sundevall have described two 
species of this genus as coming from South Africa; the smaller they 
call 4. Eleotragus, and the larger A. Isabellina. The latter author 
has given a comparative character between the two kinds, but he has 
only seen two specimens of the former (a male at Berlin and a female 
at Stockholm), and several specimens of the larger kind. I have ex- 
amined with care a series consisting of four males and five females 
from different parts of South Africa, and can find no distinction be- 
tween them, except a slight difference in the length of the fur and in 
its colour. Two specimens in the British Museum are larger than 
the rest, and have the tarsus one-fourth longer than the others ; they 
have a shorter fur and are of a rather brighter colour, and the front 
of the leg is blacker ; but the fur and colour probably depend on the 
season when they were killed. In these respects they agree with 
Sundevall’s description of A. Isabellina, but they both have the tem- 
poral spot large and quite naked, while Prof. Sundevall described the 
spot on this species as pubescent. The female of the larger specimen 
that has the black spot on the back of the head; some of the smaller 
ones have the temple-spot much smaller and less naked than the 
others. The two larger specimens have a single whorl of hair in the 
middle of the back; the others, with longer hair, show the whorls 
more distinctly, and have the hair from the central whorls to the 
shoulders forming a more or less diverging line. After examining 
these specimens and those in other collections, I conclude that they 
form only a single species. M. Sundevall, in a note just received, 
observes, “‘ Mr. Wahlberg considers 4. Isabellina and A. Eleotragus 
as very distinct, and our specimens seem to show a difference, though 
not very well expressed. Also I have committed a mistake, for the 
young female described in my Synopsis as y. under 4. Isabellina, is 
really 4, Eleotragus.”
