Species and Subspecies of Zebras. 43 
pass on to the lower surface of the belly, though without 
coming into contact with the ventral stripe. Shadow-stripes 
are visible over the quarters and flanks almost up to the 
withers, the tail is laterally banded, and the nostril-patches 
are reddish brown. 
Hamilton Smith calls this form the Congo Dauw, though 
there is no evidence that the example he figured and described 
came from that region. Matschie, on the other hand, speaks 
of it as the Damaraland zebra on the evidence afforded by a 
specimen in the Berlin Museum from the southern border of 
the Kalahari desert and from a reference to a zebra with 
white legs said by Chapman to inhabit Damaraland. 
I have had no opportunity of examining a specimen of this 
subspecies. 
Subspecies Chapmannt, Layard. 
Equus Chapmanni, Layard, Proc. Zool. Soc. 1865, p. 417. 
When Layard established this species he was apparently 
alike unsuspicious of its near relationship to #. Burchelli and 
unaware of the existence of 1. antiquorum, since the emphatic 
terms in which he speaks of its distinctness apply to it only 
as compared with the mountain zebra (ZH. zebra). From 
this point of view HL. Chapmanni is, of course, a well-marked 
form, but from antiquorum it seems to differ only in characters 
of subspecific importance. ‘There is, however, unfortunately 
no type specimen and no figure, so far as I am aware, of any 
of the original examples from which the description was 
drawn up. But provisionally, at all events, the name may 
be attached to the form figured by Dr. Sclater as Chapmann? 
(P. Z. 8. 1865, pl. xxii.), a drawing of apparently the same 
subspecies being published in Sir William Flower’s book on 
the Horse, p. 87. From the account given by Layard it 
may be gathered that Chapmanni may be recognized from 
antiquorum at all events in the union of the lower ends of 
the body-stripes with the ventral stripe. The legs, too, are 
marked, though sometimes only faintly, to the hoof. Baines, 
indeed (/. c. p. 419), comparing Chapmanni with what he calls 
Burchell’s zebra, though probably not referring to the typical 
Burchelh, mentions the extension of the leg-stripes to the 
hoof in Chapman’s zebra as compared with the stopping 
short of these marks at the hocks and knees in Burchell’s 
species as the chief distinguishing feature between the two. 
Nevertheless it is questionable what value is to be attached 
to this character in comparing Chapmanni with antiquorum, 
since H. Smith, in his diagnosis of the latter, states that the
