Hollistet — Five New Mammals from Asia. 183 



General characters. — Like Lepus swinhoei subluteus, bul with grayer 

 rump, lighter pinkish-buff chest-band, and more white on undersides of 

 fore legs. 



Skull. — Larger and heavier than skull of subluteus, with larger audita) 

 bull®. 



Measurements of type. — Head and body, 445 mm. ; tail vertebrae, 125; 

 hind foot, 118; car, LOO. Skull: Greatest length, 81); basal length, 72; 

 greatest length nasals, 38; greatest breadth nasals, 19; zygomatic 

 breadth, 42. 



Specimens examined. — Two, from the type locality. 



At Mr. Sowerby's request this hare is named for Mrs. Sowerhy, who 

 accompanied her husband on the trip during which the type was col- 

 lected and aided materially in the scientific work. 



Lepus brachyurus angustidens subsp. nov. 



Type from Tate Vania Mountain, Hondo Island, Japan. United States 

 National Museum No. \ \ ■] ',, skin and skull of c? adult. Collected De- 

 cember 14, IS82, by P. L. Jouy. 



Characters. — Like Lepus brachyurus brachyurus, but more richly col- 

 ored in both light and dark pelages; upper and lower teeth smaller, the 

 upper cheek teeth conspicuously narrower. 



Measurements of type skull. — Greatest length, 88.5 mm.; basal length, 

 71; zygomatic breadth, 44. o; least interorbital breadth, 18.3; least post- 

 orbital breadth, 10.5; greatest length of nasals, ; :!!l ; length of upper tooth 

 row, crowns, 15; greatest width upper molars, 6.2; length of lower tooth 

 row, crowns, to. 7. 



Remark*. — The northern mountain race appears to be a more richly 

 colored animal than brachyurus in any phase; that is, specimens in the 

 ordinary brown coat, and in the somewhat melanistic state common to 

 both regions, are more richly colored than comparable examples from the 

 Tokyo region. The difference in the size of the teeth is quite sufficient 

 to warrant the separation, should the color difference prove unreliable. 

 Temminck gave the distribution of brachyurus as all the Japanese 

 Empire; but as the type specimens, still in the Leyden Museum, were 

 collected by Siebold, there can he no doubt that, in dividing the species, 

 the new name should be given to the form inhabiting the northern 

 mountains. My comparisons have been made with a series of seven 

 skins and skulls from Hitachi Province, north of Tokyo. The name 

 Lepus brachyotis Swinhoe, Proc. Zool. Soc. London, 1862, p. 360, is an 

 accidental renaming of Lepus brachyurus Temminck. I am informed by 

 Dr. Leonhard Stejneger that the recognition of this additional Japanese 

 hare is in entire accord with the faunal areas of Hondo.
