206 SOME CHINESE VERTEBRATES. 



that of an old female, with the teeth all present, yet greatly worn down. The 

 condylar region has been broken away, but otherwise the specimen is in excellent 

 condition. Apparently no recent comparisons have been made between this 

 species and those close to it geographically, nor am I able to throw further light 

 on its relationships, though allowing for the worn condition of the teeth in the 

 specimen studied, it seems rather close to the Indian Sus cristatus. The vertex 

 of the skull, however, is strikingly broader. The following measurements in 

 millimeters are taken from this skull : greatest width at vertex, 63 ; greatest 

 postorbital width, 120; greatest zygomatic width, 142; length from median 

 border of vertex to tip of nasals, 306; length of nasals, 174; greatest combined 

 width of nasals, 35; palatal length, 222; upper molar row, 130; lower molar 

 row, 115; length of mandible, 282; last upper molar, 37 X 22; last lower molar, 

 41.5 X 19. 



LEPORIDAE. 

 LEPUS SWINHOEI FILCHNERI (Matschie). 



A series of nine winter and two summer skins with skulls, appears to repre- 

 sent this inland race of the common Chinese hare. All were taken in Hupeh 

 in the region about Ichang-, but none was obtained in the more western province 

 of Szechwan. These specimens agree well enough in color with those described 

 by Swinhoe and Matschie, though without topotypes of the Chefoo hare of Swin- 

 hoe, no direct comparison can be made. With the latter, indeed, Thomas has 

 suggested that filchneri of Matschie is identical, but Dr./. A. Allen (1909, p. 426) 

 considers that it is probably a valid subspecies and points out that inland animals 

 from southern Shensi have shorter rostra than those from the coast as indicated 

 by Swinhoe's measurements (1870, p. 449). On this account and on the proba- 

 bility that the inland animals would be slightly differentiated from those on the 

 coast 1,200 miles away, Dr. Allen deems it best to regard Matschie's Lepus 

 filchneri from southern Shensi as a distinct race, although the original descrip- 

 tion contains nothing that is particularly diagnostic. Our specimens agree 

 with those from Shensi in the shortness of the measurement from the postorbital 

 notch to the tip of the nasals as compared with, that given by Swinhoe for his 

 Chefoo hare. 



Thomas has further indicated that Matschie's Lepus stegmanni is doubtless 

 synonymous with L. swinhoei or the present subspecies, since the speckling of 

 the black upper tail surface with lighter hairs is not a constant character but
