34. Gerbillus t^eniurus, Wagn. 



Mount Carmel and the hill country generally. 



35. Gerbillus melanurus, Riipp. 



In the Jordan valley and Dead-Sea basin. 



36. Gerbillus pygargus, Cuv. ? 



Another small species, which appears to answer to G. pygargus of 

 Cuvier, and is found in the wilderness of Beersheba. 



37. Psammomys obesus, Riipp. 



Extremely abundant in sandy places throughout the Dead-Sea 

 basin and the plains and uplands of Southern Judsea. 



38. Psammomys myosurus, Wagn. 



Appears to take the place of the above in the higher ground. 



39. Psammomys tamaracinus, Kuhl 1 



A small Rodent met with at the south end of the Dead Sea seems 

 referable to this species. 



40. Dipus ^egyptius, Licht. 

 Very common in the desert. 



41. Arvicola amphibius, Desm. 

 Only observed by us in the north. 



42. Arvicola monticola, Wagn. 



I caught a Vole, near the snow-line on the top of Hermon, which, 

 on comparison, appears identical with a specimen in my possession 

 from the Pyrenees. If the species be identical, the range of this 

 Vole is much more extensive than has been hitherto supposed. 



43. Arvicola arvalis, De Se'lys. 

 Very common. 



44. Arvicola socialis, Desm. 



In the desert near Damascus, and probably also in Southern 

 Judsea, where we saw a very light-coloured, short-tailed Field-Vole. 



45. Glis vulgaris, Kl. 



The great Dormouse is very abundant in the oases of the Jordan 

 valley, especially about Jericho, where it has its nest in every dom- 

 tree. Through some oversight we did not bring a specimen home ; 

 but it has been mentioned by several. writers, from Russell down- 

 wards. At Jericho it was very lively in winter when disturbed. 



46. Myoxus nitela, Desm. ?
