Show 1892.] MR. O. THOMAS ON MAMMALS FROM NYASSALAND. 553 21. AULACODUS SWINDERENIANUS, Temm. a. Ad. sk. Milanji Plain, 4000 ft. 29/10/91. 22. PROCAVIA CAPENSIS, Pall. a. Imm. sk. Milanji Plain, 4000 ft.. 27/10/91. The present is by far the most northern locality hitherto recorded for this species, as, so far as I know, it has not previously been described as occurring north of Natal. The specimen is unfortunately young, and therefore the determination is to some extent doubtful; but at the same time the rudiments of the dorsal spot, just appearing, are black, and the teeth are decidedly of the hypsodont nature characteristic of P. capensis and its allies. Adult specimens of this Nyassa Hyrax would be of value in order to prove whether there is or is not any geographical difference between it and its Cape ally. 23. BUBALIS LICIITENSTEINI, Peters. a. Ad. sk. and skull. Zomba. 18/1/92. 24. OREOTRAGUS SALTATOR, Bodd. a. Imm. sk. 3 . Zomba Plateau, 5000 ft. 1/2/92. A remarkably brilliant yellow-coloured specimen. 25. iEPYCEROS MELAMPUS JOHNSTONI, Subsp. n. a. Ad. sk. and skull. 3 . Zomba. 15/1/92. Type of subspecies. b. Ad. sk. and skull. 3. Zomba. 17/1/92. A local race of the common Pallah distinguished by its slenderer skull and much shorter horns. Height, judging from the length of the skull, probably nearly equal to that of the typical Pallah, but the build, judging from the form of the same part, probably much lighter and more slender. Colours apparently precisely as in typical South African AE. melampus ; no darker markings on face. Horns conspicuously shorter than in the typical race, but otherwise very similar to them in structure and curvature, and with about the same number and arrangement of the rings. The amount of the differences in size is brought out in the comparative table of measurements (see p. 554); from it will be seen that the extreme length of the horn in AZ. m. johnstoni is barely more than once and a half the basal length of the skull (157 to 100), while in JE. m. typicus the same dimension is considerably more than twice the skull length (219 to 100). Skull of about the same length as in the typical form, but decidedly narrowev (see table), especially in the frontal region, and with the part just in front of the orbits more compressed at the sides, so that the transverse diameter at this point is decidedly less than on the muzzle above the molars, the two diameters bein«- approximately equal in the ordinary race. Palate narrow. |
