XXXIII.— Notes on the East Asiatic Members of the Species 
Sciurus vulgaris, Linn., with Descriptions of Two new Sub- 
species. By ARTHUR DE ©. Sowerby, F.Z.S., F.R.G.S. 
WHILE on a summer excursion into the biologically little- 
known district in North-eastern Chilli, China, known as the 
Tung Ling, or Eastern Tombs, | secured four specimens of 
a peculiarly dark squirrel belonging to the Sciurus vulgaris 
group. Two of these specimens were intended for the 
Smithsonian Institution, the other two being retained in my 
own collection in case of accidents. Only one of the skins 
and the two skulls of the first pair were received in Washing- 
ton, and these have recently been re-examined by me and 
compared with specimens of various other subspecies of 
S. vulgaris in the British Museum Collection, a proceeding 
that has only been possible through the extreme courtesy of 
the authorities in the two Museums concerned. I find that 
the Tung Ling specimens represent a new and distinct form, 
easily separable from S. v. rupesiris, ‘Vhos., of Saghalin 
Island, which it most nearly resembles, by its superior size 
and certain colour-differences. This form I propose to name 
‘Sciurus vulgaris chiliensis. 
In the course of making my examination I find that the 
Corean member of this group of squirrels has not up to the
