white. In the adults with worn teeth the entire pelage above js 
buffer, as well as the eye spots and ventral side of the tail. The adult 
males are brighter buff or fulvous as compared with the females, — 
which even in the adult, seem grayer, like the young. One specimen 
has the extreme tip of the tail white. The type locality, Moab, must 
be near the northern limit of its range. Dr. Phillips obtained it at 
Suweira, Nuheibeh, and Um Shomer in the Sinai region, then farther 
north at Petra, and in Syria at Wady Hesa, Wady Ain Musa, and Beir 
el Doleh. Several young specimens from one third to one half the 
adult size were collected in late April and early May at Petra and 
Beir el Doleh.

Dipodillus mariae Bonhote, Proc. Zool. soc. London, 1909, p. 792. 
This minute grayish species was but recently described on the basis 
of two specimens from the Mokattam Hills, near Cairo, Egypt. A 
single male collected by Dr. Phillips at Wady Feiran, Sinai, corre- 
sponds completely with the published description, and seems thus to 
represent the third recorded specimen. The known range of the 
species is extended considerably to the eastward by this capture. 
MicrkOTUS GUENTHERI (Danford and Alston). 
Guenther’s Vole. 
Arvicola guentheri Danford and Alston, Proc. Zool. soc. London, 1880, p. 62, 
pl. 5. | 
Eight specimens of a short-tailed yellowish vole I have provision- 
ally referred to guentheri, with the description of which they seem to 
agree. All are from localities in the valley west of Mt. Hermon. In 
the original diagnosis, the presence of five plantar tubercles is given | 
as a chief distinguishing character, but in some specimens there seems / 
to be a minute sixth one indicated. The ears project distinctly from 
the fur of the head, and instead of being well haired near their margms 
as stated by the describers of quentheri, they are clothed with wery | 
minute hairs and appear nearly naked unless narrowly examined. | ; 
The relationship of this species to M. socialis is apparently close.
