MAMMALS FROM CENTRAL CHINA. 693 



Type. Adult male. B.M. No. 11.6.1.59. Original number 

 2170. Collected 9 January, 1910. 



This is probably the species recorded as 0. causa by Dr. Allen *, 

 who had, however, only "skins with fiugmentary skulls" for 

 comparison with the single type of Dr. Lyon's species. The 

 present perfect specimens, compared with the topotypical seiies 

 of 0. causa obtained in Kan-su by Mr. Anderson, show that the 

 species is readily distinguishable, both by its greater general size 

 and its much less swollen bullae. 



No. 2071 is too young for certain determination, but it is 

 intei'esting as still retaining in place the minute milk-predecessors 

 of the small posterior incisors. The milk-teeth are pressed close 

 against the front face of the permanent teeth, between these and 

 the large incisors in front of them. 



28. Sus sp. 



2 . 2186. 30 miles S. of Feng-hsiang-fu, S. Shen-si. 



In the state of confusion to which the late Pere Heude 

 reduced the systematic arrangement of the Chinese members of 

 Sics, as with eveiy other genus with which he dealt at any length, 

 it is impossible to give a satisfactory determination of this Wild 

 Boar at pi-esent. It probably represents the Stcs oxyodontus of 

 Heude, fi'om the Upper Han, but whether that is or is not a valid 

 species I am unable to express an opinion. 



29. BuDORCAS BEDFORDL (Plate XXIX.) 



Thos. Abstr. P. Z. S. 1911, p. 27 (May 2). 

 J. 2175. 2.2189,2190. Tai-pei-san. 10,000'. 



A wholly pale bufFy species,' practically without darker 

 markings. 



Fur longer and richej' than in the available specimens of B. tibet- 

 anus, but the dates of these are not known, while the examples of 

 B. bedfordi were killed in mid-winter ; hairs of sides of neck 

 attaining 7-8 inches, and those of back 3-4. General colour a 

 beautiful glossy golden-bufiy, moi-e cream-bufF in the females, more 

 tending towards ochraceous in the male ; at least at the ends of 

 the hairs, their bases being still creamy or whitish. Darker 

 markings on muzzle, ears, hinder back, and limbs, characteristic 

 of B. tihetanus, practically absent. No. 2190 ( $ ) entirely without 

 darker hairs on the muzzle, 2175 {S) with a few, and 2189 ( 5 ) 

 with more, but the inconspicuous daiker patch so formed very 

 different from the large and prominent black mask characteristic of 

 B. tibetanus. Dorsal line not darkened at all, its hairs elongated 

 and more strongly buffy in the male, not differentiated at all in 

 the females. Limbs not obviously darkened terminally, though a 

 few isolated darker hairs are present on the carpus and tarsus.
