ALLEN: MAMMALS OF THE PHILLIPS PALESTINE EXPEDITION. 13 



AcoMYS RUSSATUS Wagner. 



Short-tailed Spiny Mouse. 



Acomys russatus Wagner, Abh. K. Bayer, akad. Miinchen, Math.-phys. cl., 

 1843, 3, p. 195, pi. 3, fig. 2. 



Of this rare species, two specimens were procured at Wady Feiran, 

 in the dry rocky country of Sinai, and so are practically topotypes. 

 Nehring (Sitzb. Ges. naturf. freunde Berlin, 1901), records one each 

 from Moab and Engeddi, Palestine, and Tristram had previously found 

 it at Massada at the south end of the Dead Sea. In describing as a 

 distinct race the specimens he found in the Mokattam Hills, near 

 Cairo, Bonhote (Proc. Zool. soc. London, 1912, p. 229) also mentions 

 a pair from Sinai that he kept alive. The known range of the typical 

 form is thus from the region of the Dead Sea through the Sinai 

 peninsula. 



Acomys dimidiatus (Cretzschmar). 



Desert Spiny Mouse. 



Mus dimidiatus Cretzschmar, Riippell's Atlas reise nordl. Afrika. Saugeth., 

 1826, p. 37, pi. 13, fig. a. 



This is the commonest small rodent in the collection. ISIany 

 specimens were taken in the Sinai region, at Akaba (head of the Gulf 

 of Akaba) and northward at Petra and Tafileh. The most northerly 

 specimen is from Wady Kerak at the southern end of the Dead Sea. 



Jaculus macrotarsus (Wagner). 



Long-footed Jerboa. 



Dipus macrotarsus Wagner, Abh. K. Bayer, akad. Miinchen, Math.-phys. cl., 

 1843, 3, p. 214, pi. 4, fig. 2. 



A single specimen from Wady Feiran, Mt. Sinai, is practically a 

 topotype of this species, which was originally described from speci- 

 mens sent from Mt. Sinai. Nehring (Sitzb. Ges. naturf. freunde 

 Berlin, 1901, p. 163), in naming schliiferi from southwestern Palestine, 

 compared it with examples from western Arabia, which he took to 

 represent macrotarsus. It seems likely that in this he was correct.
