In 1875 Blanford had described a Persian Mouse s. n. Mus erythronotus . He 

 now changes this name in Mus arianus , in consequence of the prior use of the 

 same specific denomination by Temminck in 1850 for a Japanese Mouse.

Lataste, F., (Bull. Soc. Zool. France. 1881. p. XLV) discussed the Alge- 

 rian species of the genera Dipus and Gerbillus. According to the author Dipus 

 deserti Loche = Dipus hirtipes Lichtenst., Dipus mauritanicus Duvernoy = Dipus 

 aegijptius Hasselq. Perhaps Alactaga arundinis Cuv. is not to be found in that 

 country. He collected twelve species of Gerbillidae, viz : Pachyuromys Duprasi Lat., 

 Psammomys obesus Riipp. and roudairei Lat., Gerbillus campestris Levaill., Simoni 

 Lat., garamantis Lat. and hirtipes Lat., and five species of the genus Rhambomys 

 Wagn. He divides the genus Gerbillus into two subgenera, viz : Dipodillus Lat. 

 (campestris et Simoni] and Gerbillus Desm. (type Gerbillus gerbillus Olivier) . See

 He divides the genus Mus in four subgenera Nesokia, Mus, Leggada and Van- 

 deleuria. The several species are distributed as follows : Nesokia Hardwickii, with 

 two varieties, viz: Hardwickii and Huttoni; N. bengalensis, with a northern race 

 bengalensis and a southern race kok ; N. bandicota ; N. nemorivagus ; Mus decuma- 

 nus; M. alexandrinus, with the varieties alexandrinus, nitidus and rufescens; M.
