Show 1899.] ON CHINESE MAMMALS. 575 There is no trace of any small vestigial tooth in front of the large upper premolar. The definition of the genus will therefore have to include animals with from 28 to 32 teeth, and in so handy and small a genus there is no need for further subdividing it. TALPA LONGIROSTRIS. Talpa longirostris, M.-Edw. C. E. Acad. Sci. lxx. 1870, p. 341 ; Eech. Mamm. p. 281, pl. 38. fig. 2, pl. 1 7 A. fig. 2 (1871). c3*. Tang-liu-pa, N.W. Sechuen. The single specimen of this rare Mole is uniformly coloured black with no brown shade in the fur, as suggested by the figure accompanying the original description of the species. .SLUROPUS MELANOLEUCUS. Ailuropus mclanoleucus, M.-Edw. Eech. Mamm. p. 321 (1870). 8 • Tang-liu-pa. ARCTOMYS HIMALAYANUS. Arctomys himalayanus, Hodgson, J. A. S. B. 1841, x. p. 777. A. robustus, M.-Edw. Nouv. Arch. Mus. t. vii. 1870, p. 92. 2 skins, N.W. Sechuen. These two specimens seem to agree in every respect with skins of A. himalayanus from Sikhim in the British Museum. The skulls have unfortunately been lost, but the want is filled up by those of specimens obtained by Berezowski in the same locality; and as these agree likewise with the skulls of A. himalayanus, I shall follow Dr. Blanford (Mamm. Second Yarkand Mission, p. 36) in regarding the name A. robustus as a synonym of this species. CRICETUS (CRICETULUS) OBSCURUS. Cricetus (Cricetulus) obscurus, M.-Edw. Eech. Mamm. p. 136, pl. 12. fig. 3, pl. 13. figs. 3, 3 6 (1874). 8,8,8,8,2- North Shantung. These agree in every way with the figures and description of the species, and also with a specimen in the British Museum labelled Siberia, but which may possibly be one of Pere David's collecting, as it was obtained from an agent in Paris. CRICETUS (CRICETULUS) TRITON, sp. n. Colour uniform drab, fur rather richer in tone on the dorsal line, but no distinct streak; underparts whitish, the blue-grey of the bases of the fur mixing with the white of the extreme tips. 8, $ .
