MAMMALS FROM WESTERN CHINA. 163 



" In damp forest ; no wnter, 

 " Stomach contents, earthworms. 



" 4 embiyos — mamnife 2 — 2 = 8, another specimen with 

 5 embryos."— M. P. A. 



7. Talpa longirostris M.-Edw. 

 J. 2538. Omi-san. 9500'. 



An old individual from Ynng-li-pa, jST.W. Sze-chwaii, obtained 

 by one of Mr. Styan's collectors, was previously the only specimen 

 of this species in the Museum. 



8. Uropsilus soricipes M.-Edw. 



J. 2457, 2504, 2520, 2540, 2550, 2554. $. 2489, 2527, 

 2539. Omi-san. 6000-9500'. 



Although, owing to their being occasionally deciduous, the 

 teeth of this animal may have been quite correctly indicated for 

 the type specimen by Prof. Milne-Edwards, the full normal 

 number of teeth would appear to be greater both above and 

 below than he stated. For, above, in front of the larger p^ there 

 is genei'ally present a minute tooth smaller than any other in the 

 jaw, and in the lower jaw there is a similarly minute tooth 

 immediately following the large anterior incisor. Neither of 

 these is indicated by Milne-Edwards. The full number of the 

 permanent teeth would therefore seem to be 



l-l O.i, P.|, M.| = L%2=38, 



the same as in Dymecodon. In the milk-dentition, howevei^ 

 there is an interesting difference, as there are three lower milk- 

 premolars in addition to the non-changing p^. 



Homologising the individual teeth, the full formula would 

 therefoi'e seem to be : — 



f 1 . . 3 . 4 



I 3.4 1.2.3 

 I. -< C. << - P. < M. 



I 2.3.4 123 



LI . . 3 . 4 



This formula may be compared with that of Dymecodon, as given 

 in a previous paper of the present series * . 



The chief difi'erences in the dentition of the two genera are the 

 minute size (and occasional absence) of p^ in Uroj^sihcs, this tootli 

 in Dymecodon being larger than p\ the rounder, less carnassial 

 shape of p^ in Urojjsilus, and, in the lower jaw, the extremely 

 minute size of the posterior of the two incisors (i.^) and a con- 

 siderable superiority in size of Pg over p^, these teeth being 

 subequal in Dymecodon. 



This interesting Insectivore had not been previously represented 

 in the British Museum Collection.
