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 longieosteis. 



Talpa longirostris, M.-Edw. C. E. Acad. Sci. Ixx. 1870, p. 341 ; 

 Eech. Mamm. p. 281, pl. 38. fig. 2, pi. 17 a. fig. 2 (1871). 



6 . 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 accom- 

 panying the original description of the species. 



^LUEOPUS MELANOLEUCUS. 



Ailuropus mdanoleucus, M.-Edw. Eech. Mamm. p. 321 (1870). 

 d . Yang-liu-pa. 



Arctomys himalayanus. 



Arctomys Jiimalayanus, Hodgson, J. A. S. B. 1841, x. p. 777. 



A. rohustus, M.-Edw. jS^ouv. Arch. Mus. t. vii. 1870, p. 92. 



2 skins, N.W. JSechuen. 



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. 



Cricbttts (Ceicetulus) obscueus. 



Cricetus (Cricetulus) ohscurtis, M.-Edw. Eech. Mamm. p. 136, 

 pi. 12. fig. 3, pl. 13. figs. 3, 3 6 (1874). 



(^ , 6 , 6 , (S , 2 • ^orth 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. 



Ceicetus (Ceicetulus) teiton, 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.
