Sibudeni, Zululand. Alt. 1700 m. Type. Male. B.M. no. 4.1.5.25. Original number 641. Collected 17 December, 1903. Eight specimens examined. 14. M yosor ex v a r iu s Smuts. $ . 665. Sibudeni. S . 806, 815 (1 in spirit). Umvolosi. " Zulu name ‘ Cwinini.' " They are common everywhere, inhabiting the thick grass and undergrowth along the spruits, in the vleys and at the edge of the bush, also in the bush itself, especially under fallen trees. They apparently live on the surface of the ground and do not burrow. They feed principally on small insects and are both nocturnal and diurnal."-C. H. B. G. A specimen collected at Umvolosi, B.M. no. 4.12.3.22, appears to represent a species allied to M. tenuis, but we are unable to decide definitely as it lacks its skull. 15.

Not by any means common."-C. H. B. G. 16. C ro c id u r a flavescens Geoff. 6 ■ 892. 5 . 894. Ngoye Hills. This series agrees very well with the specimens we consider typical of flavescens Geoff, which is not the case with the series from Umvolosi. " Zulu name ‘ Ngoso.' Common. Inhabits the cultivated and deserted native lands, the thick undergrowth in the vleys and on the banks of streams. Entirely nocturnal."-C. H. B. G. 17. C ro c id u r a f lavescens f l a v id u l a , subsp. n . <3 . 860, 861, 870. $ . 830, 866, 869. Umvolosi. Size smaller than in true flavescens. Colour throughout as in that animal, the tone, perhaps, slightly warmer. Upper surface rather lighter than " Mars brown " (Ridgway) ; under surface smoke-grey, frequently with a yellowish suffusion. Interramia and wrists indistinctly white in several specimens. Old males with a well-developed lateral gland, the hair covering it conspicuously whiter than the surrounding pelage. Skull and teeth much smaller and more delicately built than in true flavescens, the difference in size being very marked in the molar teeth ; m2 in the type of flavidula is only 2-6 mm. in breadth, while it is 3-2 mm. in the case of the larger form. |
