ALLEN: MAMMALS OF THE PHILLIPS PALESTINE EXPEDITION. 13 
Acomys Russatus Wagner. 
Short-tailed Spiny Mouse. 
comys russatus Wagner, Abh. K. Bayer. akad. Miinchen, Math.-phys. cl., 
1843, 3, p. 195, pl. 3, fig. 2. 
Of this rare species, two specimens were procured at Wady Feiran, 
the dry rocky country of Sinai, and so are practically topotypes. 
ehring (Sitzb. Ges. naturf. freunde Berlin, 1901), records one each 
om Moab and Engeddi, Palestine, and Tristram had previously found 
at Massada at the south end of the Dead Sea. In describing as a 
istinct race the specimens he found in the Mokattam Hills, near 
airo, Bonhote (Proc. Zool. soc. London, 1912, p. 229) also mentions 
pair from Sinai that he kept alive. The known range of the typical 
rm is thus from the region of the Dead Sea through the Sinai 
eninsula. 
ACOMYS DIMIDIATUS (Cretzschmar). 
Desert Spiny Mouse.

1826, p. 37, pl. 13, fig. a. 
This is the commonest small rodent in the collection. Many 
scimens were taken in the Sinai region, at Akaba (head of the Gulf 
Akaba) and northward at Petra and Tafileh. The most northerly 
S:cimen is from Wady Kerak at the southern end of the Dead Sea. 
JACULUS MACROTARSUS (Wagner). 
Long-footed Jerboa.

Oe 
| Single specimen from Wady Feiran, Mt. Sinai, is practically a 
to;:iype of this species, which was originally described from speci- 
més sent from Mt. Sinai. Nehring (Sitzb. Ges. naturf. freunde 
kin, 1901, p. 163), in naming schliiteri from southwestern Palestine, 
eolpared it with examples from western Arabia, which he took to 
refesent macrotarsus. It seems likely that in this he was correct.
