Show 74 MR. O. THOMAS ON THE [Jan. 5, 12. PROCAVIA VALIDA. Dendrohyrax validus, True, P. U. S. Nat. Mus. xiii. p. 227 (1890). Fur thick and close, but rather coarse. Ears short and rounded. Mammae 0-1=2. General colour dark grizzled brown, with a strong suffusion of dark fulvous. Hairs of back dark slaty grey, with a subterminal ring of orange and a black tip. Belly bright deep fidvous, quite different to anything found elsewhere in the genus. Upper surfaces of hands and feet dark brown or black, darker than the general body colour. Dorsal spot prominent, narrow, elongate, bright cinnamon or fulvous, the hairs rather darker basally. " Skull depressed, muzzle elongate, nasal bones rectangular, slightly expanded posteriorly. Orbit completed behind." (True.) T'ype'm the United States National Museum. Hab. Mt. Kilima-njaro, E. Africa (H. H. Johnston, Dr. W. L. Abbott). This species is of course that referred to by me with much doubt as " Hyrax brucei, Gray (?)," when working out the collections of Mr. H. H. Johnston from Kilima-njaro. As the skins had no skulls with them, and I did not then know how much reliance might be placed on the peculiarities of the coloration, I naturally referred them to a previously known species, rather than run the risk of describing them unnecessarily. 13. PROCAVIA ARBOREA. Hyrax arboreus, A. Smith, Trans. Linn. Soc. xv. p. 468 (1827). Dendrohyrax arboreus, Gray, Ann. Mag. N. H. (4) i. p. 49 (1868). Size medium ; form thick and squat; head not disproportionally large. Fur very long and soft; muzzle always hairy ; ears fringed. Mammae 0-1 = 2. General colour coarsely mottled fawn or yellowish grey with a certain infusion of rufous; the hairs black for their basal seven-eighths, then with a subterminal band of dirty fawn-colour, becoming darker distally, and with a decided black tip. Belly pale yellowish white, sharply defined. Dorsal spot elongate, very prominent, wholly white, the hairs white to their bases, their tips with a yellowish tinge. Skull* flattened, but not in so exaggerated a manner as in P. dorsalis. Muzzle not so markedly elongated; distance from between the postorbital processes to occiput equal to that to the tip of the nasals. Orbits ordinarily, but not always, quite complete behind. Temporal crests as in P. dorsalis. Diastema about 16 or 17 mm. in adult specimens. Molar teeth very small, rounded, brachyodont. Breadth of m1 about 6 mrn.; height of the crown of m3 3-5 ; pi elongate, two^ rooted, 3*5 to 3-8 mm. in horizontal length. 1 Good figures: De Blainv. Osteogr. iii. Hyrax, pi. ii. (this clearly is P. arborea, and not P. dorsalis as stated by Gray); Gray, Hand-1. Edent &c pi. xiii. fig. 2 (1873). |
