I have quoted "tail 174" from the label, but there is 

 some mistake ; 1 think lOO or 1(> 1 is more likely to be eorreet.

I quote dimensions from Mr. do Winton's deseri[)tion : — 



Head and body 120 mm. ; tail IGJ ; hind foot 32; ear 20. 



Skull: greatest leuirth 38 5 ; (basilar length 30 ;) greatest 

 zvg(unatic breadth 20 1; length of upper molar series 6; 

 (bnlUe 11). 



Tlie small size, bright eoloiiring, and long tail are notice- 

 able in this form as eom[)arcd with its neighbours.

About the same size as slioaiia, differing from that species 

 but little in coloration. The underside of the tail, however, 

 which in shuaiKt is white, is in this species at most a pale 

 drab or bull'. The skull is slightly smaller, more finely made, 

 and Hatter than in slioana, with markedly smaller bullte. 



The following are dimensions : — 



Head and body 130 mm.; tail 175; hind foot 36; ear 20. 



Skull : greatest length +0; basihir length 31 ; zygomatic

Notwithstanding the (litfcrencc of altitude of the localities 

 from wiiicli they came, 1 can find nothing by which to 

 distintjuish th(; Kitui spcdmei) from those from the coast. 



Prtcrs has desi-ribed a ^)t'(.:k's/curo(/ti.s/er from Mozaml)iquc. 

 Unfoitunati'ly his desci ipticni, thciugh long and detailed, is 

 throughout based on a comparison with " Meriones Sclileyeli, 

 Smith [M. lifer, Gray).^' The Museum possesses a specimen 

 in alcohol from Peters's collection ; it is labelh'd Icucogasler, 

 but it has no character in common with leacuijasler as 

 described, and is most likely aspeiiimcn of the form identified 

 by Peters as tenuis, Smith. The type-lotality of ieucuf/uster 

 is along the sea-coast from Mozambique to the Shire Kiver.
