49G Mr. R. C. Wroughtoii on 



gives the following dimensions, viz. : — Head and body 

 (measured along curves on a stuffed specimen) 8" 9'" ( = 230 

 mm.) ; tail 7" 3'" ( = 190 mm.) ; hind foot 1" 8'" ( = 42 mm.). 



The average dimensions of the above-named two specimens 

 are : — 



Head and body 187 mm. ; tail 190 ; hind foot 42 ; ear 29. 



Skull: greatest length 47 ; basilar length 37; zygomatic 

 breadth 26 ; length of upper molar series 7 ; bullae 12-5. 



These specimens may, I think, be confidently accepted as 

 representing typical iceniura. 



(29) Tatei'a persica, sp. n. 



6. 1. 2. 5-6. Seistan. (Seistan Arbitration Commission.) 

 A large Tatera, as large as or even larger than either 

 tceniura or indica. 



The whole upper surface of a uniform pale sandy colour, 

 with no apparent black grizzling, though a certain proportion 

 of the hairs on the back are black-tipped ; an area above the 

 eyes and the cheeks paler, giving the impression of a darker 

 band from the suout over the crown between the ears; the 

 dark band above and below the tail showing more admixture 

 of black than the dorsal area, the terminal black " tuft " 

 about one fourth of the total length of the tail. The skull 

 strong and broad, and the upper incisors very stout and 

 broad. Unfortunately the dimensions were not recorded by 

 the collectors, but I give the following as probably correct : —

4.6.1.3. Kerman, Persia {Sykes). Alt. 5700'. 



Rather smaller than typical per.nca. Ground-colour much 

 as in that species, but a very marked black grizzling on the 

 posterior dorsal area above the root of the tail ; the dark 

 bands of the tail are also much darker than in persica, and 

 the terminal ''tuft'^ occupies about one third of tail-length. 

 The .'*kull is broad as in persica, but neither it nor the molars 

 are so stout. The emargiuation of the anterior border of
