Mr. O. Thomas on a new Species of Meriones. 147 
Skull stouter and heavier. Nasals of more equal breadth 
throughout, not so markedly compressed and pointed ante- 
riorly, nor so much bowed in profile. Frontal region broader, 
and the postorbital processes projecting much further out from 
the skull. 
Dimensions.—Head and body (from skin) (c.) 450 millim., 
tail, with tuft, (c.) 60, ear from crown behind 83, hind foot 
107. 
Skull: greatest length, from occiput to gnathion, 83; 
nasals, greatest length 35, combined breadth anteriorly 15 
(against 11°5 in a good Shanghai specimen of L. s. typicus), 
posteriorly 18°8 (against 19°2); least interorbital breadth 21 
(against 18) ; least intertemporal breadth 12°2 (against 12-2) ; 
distance from the bottom of the postorbital notch to a point 
on the outer edge of the postorbital process level with it 
transversely 8 (against 5°4). Palate, length 34. Diastema 
22. Breadth of palatal bridge 7. Antero-posterior diameter 
of bulla 10°5 (against 11:8). 
Hab, Soul, the capital of Corea. 
Type a skin obtained on Jan. 28, 1889, and presented to 
the Museum by Mr. Charles W. Campbell, of Her Majesty’s 
Consular Service. 
As the Museum at present possesses only summer skins of 
L. sinensis typicus, it is possible that the above differences in 
colour will prove to be only a seasonal character; but the 
skull differences are so marked and so constant in a series of 
S. Chinese skulls that I do not feel justified in allocating the 
Corean hare to the older-known form, 
Should, however, the colour differences prove to be con- 
stant throughout the year it is possible that it will be found 
necessary to elevate L. sinensis coreanus to the rank of a 
distinct species.

4 THE Gerbille now described belongs to the group known as 
Meriones, a group which, in agreement with Brandt and 
Lataste, and differing from I’. Cuvier, Blanford, and Biichner, 
I consider differs so essentially from G'erbillus as to merit its 
retention as a distinct genus. 
I propose, in honour of its discoverer, to name ine species
