Show 1905.] MAMMALS FROM ZULULAND. 261 blackish, as in A. iris, while the sides and under surface are still i utous, as in true hottentottus. But even the belly, in the most strongly marked examples, is of a rather smokier rufous than in the typical subspecies. Dimensions of the type :- Head and body 120 mm.; hind foot 14. Skull-greatest length 27 ; greatest breadth 17 ; height 1 2 -5 . i i ah. of type. Notinsila, W. Pondoland. Other specimens from Port St. John. Type. Male. B.M. no. 4.6.6.4. Collected 10 February, 1904, by Mr. H. H. Swinny. Four specimens examined. The true A. hottentottus, of which the type is in the Museum, is a reddish animal, not or very slightly darkened on the back, llie specimen from Zuurbron, near Wakkerstroom, obtained by Mr. Grant, and mentioned in our previous paper, agrees closely with the type, and other reddish specimens from King Williams-town and Albany are in the collection. The species described as Chrysochloris holosericeus by Lichtenstein and C. rutilans by W agner seem to be clearly referable to the true A. hottentottus. C. albirostris Wagn. is also a reddish form, but may prove to be distinct. Its identification with C. leucorhina ITuet by Pousargues * is based on a mistake, for Wagner stated clearly in 1855 t, though he did not in 1841 J, that it had only 36 teeth, a statement which was overlooked by Pousargues. Another member of the genus which we may take this opportunity of describing is A m bly somus c h r y s il l u s , sp. n. Nose-pad broad, more than twice as broad as long, its lateral corners angular, but not produced backwards into a long sharp point as in Chrysochloris; transverse groove or infolding little prominent, not running to the lateral edges. Nostrils extremely complicated, even more so than in C. asiatica, the opening nearly blocked up by in-growing foliaceous projections. Size comparatively small. Large claw of fore foot small, slender, less curved than in A. hottentottus; its length 8'5 mm., its basal diameter 3*2 ; the small outer claw about | the length of the large one, therefore longer in proportion than in the allied species. General colour pale, much paler than in any other species; the hairs of the upper surface with only their extreme tips brown (" wood-brown" in a specimen skinned out of spirit), the greater part of their length being silvery whitish (with a tinge of yellow in the type, but this is probably due to the spirit), very slightly greyer at their bases. The brown is as usual most intense on the # Aun. Sci. Nat. (7) iii. p. 268 (footnote), 1896. f Schv. Saug. Supp. v. p. 581. J Op. cit. ii. p. 124. |
