In the account of S. /. portus it was stated that that race was 
rather yellower than the mainland form, but the fresh material shows 
that the contrary is the case especially about the rump and base of 
tail. In both races the base of the fur of the upper side is pale grey ; 
the large series of S. f. portus (26 examples ) is very variable in that 
respect ; many are as grey as the mainland pair but again many have 
the grey very pale and confined to the extreme roots of the hair. 
There are no other differences between the two: both have 
black eye and soles. 
Dr. Anderson when discussing the squirrels of this type? classed 
them all as forms of Sciurus ferrugineus, F. Cuv., but, finlaysont, dating 
from 1824, is the older name in the group if we admit the 1elatedness 
of many of the squirrels of Burma and Siam as Anderson maintained. 
The latest review of them is that of Mr. R. C. Wroughton in the 
Annals and Magazine of Natural History 3 under the title “ On the 
forms of Squirrel hitherto classed under Sc. finlaysoni, Horsf.” 
Therein S. ferrugineus of Burma and S, cinnamomeus, Temm., 
of Siam are given rank as distinct species on the ground that the 
former has black feet while the latter has not, but the reason seems 
inadequate for regarding these as other than subspecies of ferrugineus. 
Further it seems to me possible to arrange the forms dealt with 
by Mr. Wroughton in such a way that their affinities are more clearly 
shown than is the case in his valuable paper. ‘The present notes, 
however, are only of a tentative nature for | have had no opportunity 
to see the whole of the material of which they treat. 
First then come the red ferrugineus with the subspecies cinna- 
momeus (and possibly other races to be distinuished from the main- 
land ), together with frandseni, mihi, from Koh Chang: these are large 
squirrels with a greatest length of skull of about 56 mm. and appear 
to be quite distinct from those mentioned below. 
Next, on account of similar size, may be placed harmandi 
M-Edw., of Phu Quoc and albivewilli, mihi, of Koh Kut, both of which, 
being island forms, we may for the present regard as species though 
perhaps related to those following. 
Of the remaining animals the white jinlaysoni, Horsf. is re- 
corded from the course of the Menam south of Pichit, the Korat
