569 On Two new Gerbils from Sinai. 
This gerbil is probably most nearly related to the large 
Egyptian species G. pyramidum, but_is distinguished by its 
broader skull and larger bulle. It is decidedly larger than 
the Tripoli G. tarabult. 
Named in honour of its discoverer, the well-known 
Director of the Giza Zoological Museum. 
Gerbillus bonhotei, sp. ne 
Near G. andersonz, but with larger bulle. 
Size and other essential characters as in andersoni, but, as 
compared with specimens from the Nile delta, the coloration 
throughout of the more bright “ gerbil-colour”’ type, the 
dorsal colour clear light buffy, less brown, and the white, 
whether of ear-spots, belly, or feet, more vividly white and 
more extended in area. Soles well covered with hair except 
on a small spot under the heel. Upper surface of tail buffy. 
Skull very much as in andersoni, but the bulle decidedly 
and uniformly larger. : 
Dimensions of the type :— 
Head and body 97 mm. ; tail 123; hind foot 27; ear 16. 
Skull: greatest length 29°8; condylo-incisive length 26 ; 
zygomatic breadth 16°6 ; nasals 11:1; interorbital breadth 6 ; 
breadth of brain-case 14°4; palatal foramina 5:1; bulle 
(measured as in the previous species) 11°1X63 5 upper 
molar series 4. 
Hab, Northern Sinai. Type from Khabra Abu Guzour, 
S.E. of El Arish. One specimen from Wadi Hareidin. 
Type. Adu't female. B.M. no. 19.5. 7.5. Original 
number 887 (8046 of Giza Museum). Collected 25th De- 
cember, 1918, by Capt. 8. 8. Flower, and presented by the 
Giza Zoological Service. Four specimens in all. 
This species is evidently the representative from a more 
strongly desert area of the G@. andersoni of Lower Egypt, and 
is readily distinguishable by its larger bullee. In its brightness 
of coloration it differs from typical andersonz, but is imitated 
by specimens from the Wadi Natron, which are also brighter 
than those from the dark soil of the delta. All the Egyptian 
specimens, however, have the same comparatively small 
bullae. 
It is named after Mr. J. L. Bonhote, Capt. Flower’s 
colleague at Giza, who has done so much to forward our 
knowledge of the small mammals of Egypt.
