48 Mr. O. Thomas on the 
causing the muzzle in that sex to be conspicuously more 
developed than in the female. ‘This difference has been 
taken again and again for a racial character, but is really 
only a sexual one. 
As to size, those from the north of the area—Rhodesia— 
average larger than the more southern ones, but the difference 
is not very great; while of other cranial characters there do 
not seem to be any at all, and the teeth are alike throughout. 
Colour-characters are therefore the only means of sorting 
the races, and.on this account I should consider all to belong 
to but a single species—G. crassicaudatus—with several 
local subspecies. 
The type-locality of crassicaudatus itself, not known at the 
time of description, has first to be settled, and on this [ 
should accept the first authoritative identification of specimens 
and statement of locality, which were made by Peters in 1852. 
He says that Geoffroy’s type-specimen “ stainmnt ohne Zweifel 
ebenfals aus Mossambique her,” and identifies with it his 
own specimens from various places, of which Quelimane is 
the first to be mentioned. I should therefore take that as the 
type-locality. : 
As a consequence, Gray’s kirkii from the same place 
becomes an absolute synonym of crassicaudatus, and his type- 
specimen is a topotype of it. 
With regard to the next name on the list, garnette of 
Ogilby, commonly assigned to ‘‘ Natal,” I find that the skull 
of the type—which is in the Museum, in spite of Elliot’s 
assertion to the contrary—is distinctly too small for any 
S.-African Galago at all, while it exactly agrees with two 
from Zanzibar Island (coll. Sir J. Kirk and C. H. B. Grant), 
representing G. agisymbanus, Coquerel. 
As the locality of the type was nowhere recorded, and was 
definitely stated in the MS. Catalogue of the Zoological 
Society’s Museum to be “ unknown,” Zanzibar is as likely a 
locality as Natal, and I therefore propose to accept it for the 
Galago of that island. It would thus be the first of the 
Hi.-African series of names, and would antedate Coquerel’s 
agisymbanus. 
The following are the four subspecies of crasstcaudatus 
which appear to me to be recognizable, taking them from 
north to south :— 
1. G. crassicaudatus monteiri, Gray. 
Wholly grey. 
Angola (Monteiro, Ansorge), N. Rhodesia and Angoniland 
(Neave, Melland, Mrs. Colville).
