Show 444 MR. O. THOMAS ON MAMMALS [June 3, of the utmost value, and increasing very considerably the interest of the specimens. 1. ANTHROPOPITHECUS TROGLODYTES, Gm. a. S • " Skull of a full-grown Chimpanzee shot by m e in Mssou-gua, shores of Albert Lake, the first specimen ever obtained in these regions."-E. 6. 5 . Skull without mandible. No exact locality. Specimen a is an unusually fine male skull, measuring 198 millim. from occiput to gnathion, and 138 in its greatest bi-zygomatic breadth. There appears to be no essential difference between it and ordinary West-African Chimpanzee's skulls; and in regard to " Troglodytes schweinfurthi" and " T. niger var marungensis," I can only repeat m y opinion of 1888 \ namely, that the evidence is as yet too meagre for their proper distinction. 2. HERPESTES GALERA, Erxl. 3 . Monda, Nguru Mountains. A remarkably handsome specimen, strongly influenced by ery-thrism, many of the hairs, especially those on the belly, being wholly or partly of a brilliant rufous colour. 3. HELOGALE PARVTJLA TJNDTJLATA, Peters. a. 2 • Usambiro, S. Victoria Nyanza. 1/9/89. b. 6". Usagara. 22/11/89. " Iride fusca. Native names (a) " Ndjororo " and (b) " Viguiri." Common in little flocks of from 6 to 10 individuals, running about the fields."-E. Although, on the whole, I a m disposed to agree with Dr. Jentink2 as to the specific identity of H. parvula, Sund., and H. undulata, Peters, yet the difference in the colour of typical examples of each is such as to render it advisable to consider the two as representing different geographical races-a southern semi-tropical, and a northern tropical one respectively. Dr. Emin's observation as to the gregarious habits of the species is of remarkable interest, and is, I believe, the first observation of the sort made about any member of the family. 4. RHYNCHOCYON PETERSI, Bocage. a. Mandera. 3/90. Coll. Langheld. The present is the third specimen of this rare species that has been received by the Museum. The first was obtained on the island of Zanzibar by Sir John Kirk in 1884; and a second one, a fine male in spirit, in the Rabai Hills, Mombasa, by the Rev. W . E. Taylor in 1886. All the three agree precisely with the original description given by Prof, du Bocage3, of which an abstract was published by Dr. Giinther in his monograph of the genus4. 1 P. Z. S. 1888, p. 5. 3 J.
