312 Mr. M. A. C. Hinton on 
tinged with yellow anteriorly. Outer surfaces of limbs, 
particularly of the fore limbs, greyer and less ochraceous 
than in the southern forms. Inner surfaces of limbs and the 
underparts pure white. Dorsal surfaces of feet dull ochra- 
ceous buff. Tail normal, many ochraceous hairs appearing 
on ventral surface ; the terminal hairs rufous. 
Collector’s measurements.—Head and body 161 mm.; tail 120; hind 
foot 36; ear 18. . 
Skull: condylo-incisive length 36 mm. (ca.); dental length 18:5; 
zygomatic breadth 23; cranial width 19:1; upper cheek-teeth (crowns) 
76; 2-4 in place, about half-worn. 
Paraxerus flavivittis ibeanus, subsp. n. 
Hab.—Mombasa, British Hast Africa. 
Type.—A skin (B.M. 80.11. 30.6) collected and presented 
to the British Museum by Dr. (afterwards Sir. J.) Kirk. 
Size and general characters as in other subspecies of 
flavivittis. 
General dorsal colour strong fulvous ochraceous, somewhat 
lighter, yellower, and less rich over shoulders and rump. 
Shoulder-mantle quite inconspicuous, represented merely by 
the lightening in the general hue just mentioned. Lateral 
dorsal stripe pale yellow, somewhat broader than in eageanus, 
but still shorter ; the band between the light stripe and the 
grey flank on each side concolor with mid-dorsum, narrow. 
Facial markings inconspicuous. Upper surfaces of hands and 
feet buff ; underparts white. Tail normal. 
ALIV.— Three new Subspecies of Spalax monticola.

LIKE other strictly fossorial mammals, mole-rats of the genus 
Spalax show a well-marked tendency to develop local races 
characterized by more or less obvious differences. No doubt, 
that form of segregation which must result from a very 
limited area of individual distribution and local differences in 
soil and food are to be looked upon as constituting together 
the mainspring of this variability. The differences between 
race and race in such cases are apt to be very small and 
trivial ; but, nevertheless, they show frequently a remarkable 
constancy in their occurrence.
