296 MR. OLDFIELD THOMAS ON [ Apr. 21, 
nasals (diagonally) 49; interorbital breadth 26; breadth across 
postorbital processes 37; breadth of brain-case 49°5; palate, 
length 72°5; breadth between outer corners of p.* 44. 
Teeth: length of p.* 9-6, of p.* (on outer edge) 14:2, of m.* 11, 
of m.1 and m.”* combined 16°8; breadth of m.* 14, of m. 10. 
(Below), length p., 8°7, of p., 10, of m., 17°3, m., 81. 
Hab. and type as given above. 
This is the Jackal figured by Cretzschmar’* from Riippell’s 
specimen as C. anthus, but is clearly at least subspecifically 
different from that animal. Mr. de Winton has recently shown ? 
that none of the earlier names of Hemprich and Ehrenberg or 
other authors apply to this form, and I therefore venture to bestow 
one on it.

The rediscovery of this species is of interest, as there has always 
been some doubt whether it was or was not the same as the more 
northern J. lybica. It proves to be readily distinguishable by its 
smaller size, by certain differences in its body pattern, and, 
especially, by the absence of the black ends to the caudal hairs.

A topotype of the species. As already noted °, the specimen in 
the Stuttgart Museum marked Meriones stigmonyx does not agree 
with Heuglin’s description of this animal, and is more like that of 
his If. dongolanus. 
It is to be observed that the present Gerbille and the next one 
are so extremely alike, that it is almost impossible to distinguish 
them apart except by an examination of the soles and skulls. 
There is, however, a darker median area (“‘ Scheitel und Riicken- 
mitte satter gefirbt”) in the Dipodillus not present in the 
Gerbillws, and this confirms my previous allocation of the name, 
which in any case having once been made should be adhered to.

A small species of true hairy-footed Gerbillus, with compara- 
tively short tail.
