492 Mr. R. C. Wrouglitou on 



Skull: greatest lenjifth 45 ; (basilar length 35 ;) zygomatic 

 breadth 24; length of upper molar series 7 ; bullie 12. 



Noteworthy cliaractcrs in this species are large size, very 

 long tail, and indistinct grooving of incisors. 



(21) Tatera sUoana, sp. n. 



98.6.9.8-9. JeHr Medir and Ujawaji, Somaliland 

 {Hawker and Chetham). Alt. 5000'. 



2. 9. 9. 18. Lake Zuai, Abyssinia [Degen). 



79. 1 1. 1 1. 4-5. Galla Country [Gerrard). 



Much larger than Pliiilipsi, ground-colour duller than in 

 that species. Mr. de Winton records "no ear- or eye- 

 patches " in PlnUipsi : this is not quite correct ; though not 

 strongly marked, there are distinct pale areas between the 

 eye and ear and behind the ears at their bases, and this is 

 equally true of this species. The terminal third of the tail 

 is clothed above with long Idack hairs, recalling the tufted 

 tails of the forms of the Nile Valley ; but it is not so 

 marked, nor does the black coloration extend to the lower 

 surface as in those Ibrms. 



The following are dimensions : — 



Head and body 140 mm. ; tail 180; hind foot 36 ; ear 20. 



Sknll : greatest length 41 ; basilar length 32 ; zygomatic 

 breadth 21 ; length of upper molar series 63 ; bullae 11"5. 



Hub. Jefir Medir, Somaliland. 



Type. B.M. no. 98. 6. 9. 8. An old female. Collected by 

 Messrs. Hawker and Chetham, 31st December, 1897 (two 

 specimens), and presented to the Museum. 



The long black hairs at the tip of the tail almost forming 

 a tuft distinguish this from all other forms yet known except 

 those from the Nile Valley. 



(22) Tatera Kempi. 



Tatera Kempt, Wroughton, Ann. & ]Mag. Nat. Hist., April 1906, 

 p. 375. 



5. 12. 1. 8. Anambra Creek, S. Nigeria {R. Kemp). 



A medium-sized Tatera with an extraordinarily long tail. 

 The colouring s rather dull, the ground-colour being a very 

 brown shade of the usual " fawn ^^ or "sandy"; otherwise 

 there is no noteworthy external character. The skull is 

 large for so small an animal, and in shape is markedly long 

 and narrow ; the groove of the incisors is well marked and is 

 more than ordinarily outside the median line. 



The dimensions are (those of tiie body recorded by the 

 collector) : — 



Head and body 145 mm. ; tail 174; hind foot 35; ear 20.
