the Genus Tafera. 491 



colour-forms, which, so far as the material available is 

 concerned, are perfectly constant o:eo{;ra|)lii('ally. The 

 present form, representiii}:^ the fauna south of L ike Nyasa, 

 is a medium-sized animal, in which the ground-colour is 

 rather of a brown-sandy colour and in which the black 

 shading is so copious as to give it a very markedly dark and 

 sober appe;iranre. 



The (liuuiisions are (approximately for body-measure- 

 ments) : — 



Head and body 150 mm. ; tail 150 ; hind foot 32; ear 19. 



Skull: greatest length 37; basilar length 29; zygomatic 

 breadth 18 ; length oF upper molar series 6 ; bullaj 10.

96. 5. 29. 5. ]Mumia, Kaviroudo {Ansorge). 



A small species about the size of angola. 



Ground-colour a dark rufous buff, very much washed with 

 black, especially along the centre of the buck and upper 

 surface of the tail. In some specimens this darkening is so 

 complete as to make them look almost black. Under 

 surface white as usual, but lower surface of the tail buff and 

 not clear white. The molars are stout and broad and the 

 bullae large for the size of the skull, and the grooves of the 

 incisors but slightly marked in old specimens. 



The dimensions are as follcAvs : — 



Head and body 135 mm.; tail 110; hind foot 32; ear 20. 



Skull : greatest length 38; basilar length 30 ; zygomatic 

 breadth 20 ; length of upper molar series G ; bullae 11.

Type. B.M. no. 2. 11. 1. 12. An adult female. Collected 

 by L)r. Ansorge on the 1th August, 1897. 



Its (lark colour, smaller size, and large bull?e distinguish 

 it at once from the Nyasan forms.
