white. In the adults with worn teeth the entire pelage above is 

 huffier, 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. 

 Mrs. Bonhote's Pigmy Gerbil. 



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. 



MiCROTUS GUENTHERi (Danford and Alston). 



Guenther's Vole. 



Arvicola guentheri Danford and Alston, Proc. Zool. soc. London, 1880, p. 62, 

 pi. 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 margins 

 as stated by the describers of guentheri, they are clothed with very 

 minute hairs and appear nearly naked unless narrowly examined. 

 The relationship of this species to M. socialis is apparently close.
