Mammals from Lumbo, Mozambique. 31 



4. Helogale ivori, sp. n. 



S . 227, 228 ; ? . 200, 229, 233, 234. _ 



A buffy species, resembling i/. victorina in colour, but 

 Z7. brunnula in its comparatively small size. 



Size small, skull not or barely reaching 50 mm. in length. 

 General colour very uniform buffy — that is to say, the body 

 is so buffy that the limbs and tail are less contrasted with it 

 than usual. Back nearest to " cinnamon-buff," the usual fine 

 brown and whitish ticking of the hairs modifying it less than 

 in other species. Under surface strong ochraceous tawny. 

 Muzzle and cheeks more tawny. Crown slightly greyer and 

 rump a little more ochraceous than back, but these contrasts 

 are very markedly less conspicuous than in the Mweru 

 H. varia. Limbs ochraceous tawny. Tail rather shorter 

 than in other species, grizzled buffy above, strong ochraceous- 

 tawny below. 



Skull small, about as in H. brunnula, markedly smaller 

 than in the Central and East-African forms victorina, 

 rufula, &c. 



Dimensions of male and female (the first the type) : — 



Head and body 242, 210 mm.; tail 145, 140; hind foot 

 43, 40; ear 20, 20. 



Skull : median length 49*8, 49*3 ; condylo-basal length 

 49-3,49-2; zygomatic breadth 28-3,27*2; interorbital breadth 

 10-3, 9-8 ; palatal length 24'2, 24*3 ; maxillary tooth-row 

 17-2, 17. 



Type. Adult male. Original number 228. Killed 22nd 

 October, 1918. 



This species is conspicuously more buffy and less rufous 

 than Peters's H. undulata, which was described from Mos- 

 siniboa, some distance further northward. It has a superficial 

 resemblance to the Uganda form H. victorina, but is smaller, 

 more uniform in colour, and the tail is decidedly shorter. 

 The Mweru species H. varia, which seems to have as short a 

 tail, is larger, and has an unusually dark grey crown and 

 more strongly buffy rump, both conlrasting with the dorsal 

 colour more than in H. ivori. 



Named after the Hon. Ivor Montagu, to whose interest in 

 small mammals the donation of the specimens is mainly due. 



5. Paraxerus flavivittis mossambicus, subsp. n. 



? . 202. Lumbo, 1st September, 1918. Type.
