of the Burchell’s zebra “ Matopo,” which was the previous sire. 
The same remark is equally applicable, so far as I have seen, to the 
other subsequent foals in respect of their hair characters. 
I must express my indebtedness to Professor Ewart for provid- 
ing the greater part of the material used, for kindly allowing me 
the use of the blocks from which Plates I.-IY. are reproduced, and 
for assistance in various other ways. To Mr Beddard, Prosector of 
the Zoological Society, I am indebted for what other material has 
been employed. In conclusion, I have great pleasure in thanking 
Sir Thomas Gibson Carmichael, Bart., for his very generous 
support. 
Postsci'ijpt, July 31st . — Since writing the above, Professor Ewart 
has been good enough to obtain for me, through the kindness of 
Mr Oldfield Thomas, some mane and shoulder hairs from a zebra 
skin recently brought home from Angola by Mr W. Penrice. Mr 
Thomas* describes the skin as possessing “ the deeper and more 
essential characters of Equus zebra , such as the forward slope of 
the median dorsal hairs, the presence of a ‘ gridiron pattern ’ on 
the rump,” etc., but differing from it “ so much in other details that 
it clearly cannot be assigned to the typical form of that species.” 
Mr Thomas adds that since it is isolated geographically from 
E. zebra , which is only known from South Africa, and differs 
from it in so many respects, in the absence of evidence of the 
existence of intermediate forms, it must be regarded as a distinct 
species, which he calls Equus Penricei. 
The characters of this animal’s skin are briefly described by Mr 
Thomas.* I find that the individual hairs from the region of the 
shoulder resemble closely those of the Somali zebra (E. Grevyi), 
which, according to Mr Thomas, Penrice’s zebra also resembles in 
“ the equal striping of the body, the short close fur, and the huffy 
tone of the light stripes.” The following are measurements of a
