In the account of S. f. portiis it was stated that that race was 

 rathei\yellower than the mainland foi-m, but tlie fresh material shows 

 tliat tlie contrary is tlie 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. partus ( 26 examples ) ii very variable in that 

 respect ; man}^ are as gre^' 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 : botJi have 

 black eye and soles. 



Dr Anderson when discussing the squirrels of this type-' classed 

 them all as forms of Sciarus ferrur/vnens, F. Cuv., hut, Jinlai/soni, dating 

 from 1824, is the older name in the group if we admit the ) elatedness 

 of manj'^ of the squirrels of Burma and ISiam as Anderson maintained. 

 The latest review of them is that of Mr. II. C. Wroughton in the 

 Annals and Maf/azine of Natural Historij '^ under the title " On the 

 forms of Squirrel hitherto classed under Se. finlaysoni, Horsf." 



Therein , S . ferriigineus 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 i-egarding these as other than subspecies of ferriir/ine'us. 



Further it seems to me possible to arrange the forms dealt with 

 b}^ Mr. ^Vroughton in such a way that their affinities are more clearly 

 shown than is the case in his valuable Ijaper. The present notes, 

 however, ai'e only of a tentative nature for I have had no opportunity 

 to see the whole of the material of which they treat. 



First then come the red ferr^Kjineus with the subspecies cinna- 

 momeus ( and possibh'' other races to be distinuished from the main- 

 land ), together \\\i\\ frandseni, mihi, from Koh Chang: these ai-e 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 liarmandi 

 M'Edw., of Phu Quoc and alhifexilli, miiii, 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 i-emaining animals the \\\\\\e jiidaijsnni, Horsf. is re- 

 corded from the course of the Menani south of Pichit, the Korat
