Hab. ad Kohrud in Media. 



This mouse is allied to M. sylvaticus. 



8. Gerbillus jpersicus, sp. nov. 



G. affinis G. indieo, supra ferrugineus, infra albus ; Cauda corpus 

 longitudine excedente, superne rufescenti-brunnea, apicem versus 

 nigra, subtus albida, ad latera haud pallide striata ; auribus longis, 

 sed minoribus quam in G. indieo, parum pilosis, plantis latioribus, 

 subtus sordide viridescentibus, vibrissis longioribus confertioribus- 

 que ; dente molario superiore postico in adultis simplici rotundo. 



Long, corporis cum capite 6-25, caudae (vertebrarum) 6-5, pilorum 

 ultra apicem 1, cranii 1*75, auris 0*85, palmas 0*6, plantae 1-55 

 poU. 



Hab. in Persia. 



This species, though very near G. indicus, is at once distin- 

 guished by wanting the dark line down the lower surface of 

 the tail j the shape of the skull, too, is very different. 



9. Gerbillus nanus, sp. nov. 



G. parvus, longicaudatus, cauda corporis longitudinem duplam 

 sequante, supra cervinus, infra albus, genis superciliisque albidis ; 

 cauda superne brunnea, subtus albescente, apice vix fuscescente, 

 pilis apicalibus vix elongatis ; auribus mediocribus, fere nudis ; 

 mystacibus plerumque albis, superis ad basin fuscis. 



Long, capitis cum corpore 2-6, cranii 1*05, caudae (pilis apicalibus 

 inclusis) 5, auris 0*45, plantae 0*9 poll. 



Hab. in Gedrosia (Baluchistan). 



One of the smallest forms of the genus. A very closely 

 allied species is common on the Abyssinian coast of the Red 

 Sea, and was, probably incorrectly, referred by me to Dipus 

 Gerbillus, Olivier. 



10. Dipus Lqftusi, sp. nov. 



D. supra fusco-isabellinus ; pilis mollissimis, basin versus pallide 

 griseis, ad uropygium duntaxat nigro terrain atis ; subtus albus ; 

 femore extus fascia lata alba transversa signato, postice baud 

 fusco ; mystacibus brunneis ; auribus rotundatis, mediocribus, 

 intus extusque pilis sparsim indutis ; cauda supra brunnea, subtus 

 pallida, apicem versus nigra, albo terminata. 



Long, corporis cum capite 5-6, caudae (vertebrarum) 6, pilorum ultra 

 apicem 0*75, auris 0*75, tarsi cum pede posteriore 2 poll, (dimen- 

 sionibus ad corium exsiccatum mensis). 



Hab. ad Mohumrah in Mesopotamia (teste Loftus). 



This species belongs to the subgenus Scirtopoda, section 

 Haltomys of Brandt. It is distinguished from all its allies by
