148 Mr. O. Thomas on a new Species of Meriones. 
Meriones Tristram, sp. n. 
Size rather small, about equal to that of M. meridianus, 
Pall. ars rather long and narrow, laid forward they reach 
beyond the middle of the eye. Fur long and soft. Colour 
above dull fulvous, grizzled with black, the general tone not 
unlike that of M. Shawt. Underside, hands, and feet white. 
Palms quite naked, granulated, with three small distal and 
two large proximal pads. Soles mainly hairy, but with a 
naked stripe running from the heel forwards to just past the 
tarso-metatarsal joint; distal part of sole cushioned, granu- 
lated, very thinly haired, with four minute pads at the bases 
of the digits and a rudiment of a fifth posterior internal pad 
just distinguishable. ‘Tail grizzled yellow and brown above, 
with a small black terminal crest and pencil on its distal 
inch ; uniformly yellow or white below. 
Skull, for a Mertones, slender, narrow, and delicate, but 
little flattened and broadened across the parietal region. 
Bulle very small for the genus, the neck of the auditory tube 
not dilated anteriorly towards the zygoma, as is the case in 
M. meridianus and other allied species. 
Incisors slightly bevelled, each with a single groove. 
Molars of the most Merdones-like character, 7. e. hypsodont, 
with lozenge-shaped laminzeconnected with each other through- 
out. 
Dimensions of the type (an adult male in spirit) :— 
Head and body 121 millim., tail 153, hind foot (without 
claw) 32, ear (above crown) 16. 
Skull: greatest length (approximate) 37; length from 
bregma (junction of frontals with parietals) to nasal tip 25°5 ; 
zygomatic breadth 18°8; nasals, length 14-7, breadth 39 ; 
interorbital breadth 6°1; breadth across combined fronto- 
parietal sutures 12°5; (interparietal, length 5*, breadth 7°8*) ; 
length of ante-zygomatic plate 5:2; diastema 9:9; palatine 
foramina 6°8; bulla (greatest diameter 12:2 *), greatest 
diameter of tympanic portion 12°0, greatest breadth from lip 
of meatus at right angles to last measurement 8°7. Length 
of upper molar series 5°5. 
A second specimen, a female, has the head and body 110, 
tail 126, and hind foot 29°5. 
flab. Palestine. 
Type (B. M. 64. 8. 17. 35) from the Dead Sea; another 
specimen from Mount Carmel. Both collected by Canon 
H. B. Tristram. 
* The measurements in brackets are taken from the smaller female 
specimen, owing to the imperfection of the skull of the type.
