East Asiatic Members of Sciurus vulgaris. 253 
This form may be described as intermediate in colouring, 
but not in size, between the Yezo orientis and the Khingan 
and Manchurian mantchuricus. It is almost without any 
rufous colouring, either in winter or summer pelage, in which 
it agrees with mantchuricus, but is not so purely greyish, 
being more brownish, in which it agrees more with orientis. 
It is smaller than either of these two forms, and has a pro- 
portionately shorter and wider skull. 
Colour.— Winter pelage very close to orientis, but darker, 
the lightest specimens of ortentis being considerably lighter 
than the lightest of coree, while there is much less tendency 
to rufous in coree. Very distinct from chiliensis, rupestris, 
and mantchuricus; somewhat approaching colatus, but browner, 
Its general colour may be described as brownish grey, the 
feet and the long hairs of the ears and tail being blackish, 
more so than in ortentis. The feet are lightly washed with 
rufous in some specimens. Judging from the South Man- 
churian specinen, which is certainly not mantchuricus, the 
summer pelage is of a general, and more or less uniform, dark 
brown, with no rufous washing.

6. Scturus vulgaris chiliensis, sp. n. 
This is a dark form, not truly melanistic as appears -to be 
the case in the dark specimens of rupestris, with which it 
agrees most in appearance, and is characterized by its black 
or blackish-brown summer pelage, in which the legs, feet, 
lips, and flanks are rufous, the region of the face, muzzle, and 
chin inelined to greyish, with no rufous about the ears. It 
differs from rupestris in this last characteristic and in 
being distinctly larger throughout. From mantchuricus, its 
nearest mainland neighbour, it differs in being blacker in 
summer and in the presence of the rufous colouring, as well 
as in its smaller size. From the other species it is easily 
distinguishable by its darker summer pelage and dark grey 
winter coat.
