scattered places behind. Tegule large, pure white; the 
wings whitish hyaline, well tinged with tawny fuscous on 
basal half or third. 
This may prove to be conspecific with purpurascens, but it 
will at least form a good variety of that species. 
Neither of the above species belongs to any of Wulp’s 
Mexican [Tyalomyias.

Pocock, of the British Museum of Natural History. 
Part L.—ZIntroductory Remarks. 
For some years past, during periodical visits to the museum 
at Bristol, my attention has been attracted by a stuffed speci- 
men of a zebra-like animal, which, in addition to being labelled 
“ Quagea,” possessed special interest, inasmuch as it differed 
strikingly in the character of its markings from all the zebras 
in the collection of the British Museum and from all that I 
had seen in menageries and elsewhere. The true Quagga, as 
is now admitted on all hands, is extinct, and only a few speci- 
mens have been preserved in the various museums of Europe. 
Consequently the example in question, if correctly named, 
would be of great zoological interest and of very considerable 
value as a museum possession. I therefore undertook, with 
the consent of Mr. Edward Wilson, F.G.8., the curator, who 
kindly gave me every facility in the way of examining and 
sketching the specimen, to identify it, if possible, and 
ascertain as nearly as might be its affinities with regard to 
the known forms of zebras. As is explained later on, the 
specimen, though of considerable interest, proved to have no 
proper claim to the title of quagga. But the task of identi- 
fication entailed the looking up of a deal of the literature 
published on the subject by both naturalists and sportsmen 
aud an examination of all the skins and living specimens to 
which access could be obtained; and since during the inves- 
tigation a few structural points came to light which have 
apparently escaped notice until now, and since, with the 
exception of Dr. Paul Matschie’s paper alluded to below, no 
paper dealing comprehensively with all the species has been 
published of late years, I have ventured to hope that the notes 
and observations contained in the following pages, thouzh
