dark face-markino-g, and in the length of tlie posterior palatal 

 foramina, but differs in lacking- the reddish body tint with 

 black washing oE v'lcina, and in possessing small bullpe. 

 With T. lohengidoi it agrees in body-colouring, but differs in 

 tail and face-markings and in the length of the posterior 

 palatal foramina, which in lohengulce, as in all the southern 

 forms, are very short. 



Taterona tahora', s\). n. 



A grey Taterona, witli less ochraceous colour than in any 

 species hitherto described. Tail equal in length to head and 

 body, and untufted. Bulhe large. 



General colour of back mouse-grey, tinged with buff. 

 Sides clay-colour. Colour of head no darker than back. 

 Tliurs of under surface with slaty bases as in liodon, except 

 in tlie sacral region, where they are white throughout. This 

 slaty colour is strongly marked, and gives a dirty greyish- 

 white appearance to the under surface, very different from the 

 pure shining white of most species of Taterona. Hands and 

 feet white. Tail greyish brown above, white below, untufted, 

 and with no black hairs. The average length of the tail in 

 six specimens examined is exactly equal to the length of tlie 

 head and body. 



Measurements of the type (taken in the flesh) : — 



Head and body 140 mm. ; tail 130 ; hind foot 32 ; 

 ear 21. 



Skull: greatest length 39 mm.; condylo-incisive 36*5; 

 basihar 31"5 ; condylo-basilar 34; palatilar 18"2; anterior 

 palatal foramina 7*2 ; posterior 1*0 ; Sj)ace between anterior 

 and posterior palatal foramina 5*0 ; interorbital breadth 7'Oj 

 bullae 12"0 ; upper molar series 7*0. 



Dorsal aspect of skull convex^ not flattened. Groove of 

 incisors well marked. 



Type. Adult male. B.M. no. 21. 9. 5. 14. Original number 

 585. Collected by Mr. A. Lovoridge on 10th December, 1918, 

 and presented to the British Museum by Lord Swaythling. 



Type-locaUty. Tabora, 5° S., 32° 40' E., in tlie Tanganyika 

 Colony. 



The predominance of grey colouring both above and below 

 in itself separates T. tahorm from all other species of the 

 genus. T. liodon, which shares with T. tahorce the distinc- 

 tion — rare in this genus — of having slaty bases to the hairs 

 of the under surface, is at once distinguished by the slight 

 almost imperceptible grooving of the incisors.
