The Noboribetsu and Aoyama specimens are in the winter, and 
the Jozankei specimens in the summer pelage. 
In Major Barrett-Hamilton’s paper* on the subspecies of 
Sciurus vulgaris, those from the Far East, from Koreaand Hokkaido, 
are assigned to S. v. calotus Hodgs.t, whose typical locality is the 
high region of Central Asia. But the valuable series obtained by 
Mr. Anderson indicates that they are sufficiently different to have 
a subspecific name of their own. For while the type of calotus 
and other specimens from the Altai are, in winter pelage, a clear 
deep grey above without rufous suffusion, the whole of the 
Hokkaido examples are strongly suffused along the head, dorsal 
area, and base of the tail with a colour between ‘* Mars-brown ” 
and ‘‘ vinaceous-cinnamon ” of Ridgway, though paler than either. 
Sides clearer and more silvery grey, especially on two patches on 
each side, behind the shoulders and in front of the hips. Throat, 
chest, and belly pure sharply defined white, the hairs white to 
their roots. Har-tufts, hands, and feet blackish, more or less 
speckled with fulvous. ‘Tail broadly washed with black, the basal 
part of the hairs more or less greyish or fulvous. 
In summer pelage the ground-colour (apart from melanism) is 
dull reddish brown, with dark red ears and feet, and perhaps 
sometimes a more or less red-washed tail. But every specimen is 
to a certain degree affected with melanism, and the only one that 
has the body, ears, feet, and proximal half of tail red, also has the 
terminal half of the latter organ blackish, as the whole. of it is in 
the majority of specimens. 
Dimensions of the type, measured in the flesh:— 
Head and body 244 mm.; tail 175; hind foot (s,u.) 60; ear 34. 
Skull—ereatest length 54; basilar length 43. 
Hab. Hokkaido. ‘Type from Aoyama. 
Type. Adult male in winter pelaget. B.M. No. 6.1.4.128. 
Original number 98. Collected 9 November, 1904. 
Two specimens from Sdul, Korea, presented by Mr. C. W. 
Campbell, and killed in January 1889, appear to be quite similar 
to the Hokkaido Squirrel. 
This Hastern form of S. vulgaris is no doubt most closely related 
to S. v. calotus, but may be distinguished by. the rufous suffusion 
along its dorsal area. This produces, at least in the winter coat, 
a considerable resemblance to the Scandinavian Squirrel, but from 
that animal it is readily distinguished by its dark ear-tufts and 
feet, and by the sharp definition and complete whiteness of the 
colour of the under surface. 
This Squirrel is of course the Sciwrus varius of the ‘ Fauna 
* P. Z.S. 1899, p. 3. 
+ Mustela (2?) calotus Hodgs. Calc. Journ. N. H. ii. p. 221 (1842). 
+ The hands and feet of the type have some of the red of the summer coat still 
on them, and this specimen is not, as I at first thought, an exception to the rule 
that the Hokkaido Squirrel has dark feet in the winter pelage.
