I have examined a very extensive series of squirrels ^ from the Malayan penin- 

 sula and its neighbouring islands, and from the large Islands of Sumatra, Borneo, 

 and the Celebes, and all of which appear to be referable to one specific form, which, 

 however, is so modified in certain comparatively limited, areas as to assume the im- 

 portance of local races. The attempt, however, to elucidate and define these races 

 is comphcated by the changes of fur to which these squirrels are subject before they 

 reach maturity, and probably by alterations of pelage attending the breeding season. 

 There appear to be three well-marked, local races, — one peculiar to Malacca 

 and the mainland, another to Sumatra and Banka, and perhaps to some of the 

 neighbouring smaller islands, and a third to Borneo and the Celebes. 

 The features which characterise the first race are as follows : — 

 The Malayan race. — The side of the face and lower jaw from the muzzle, 

 below the eye, and through the lower third of the ear, and along the side of the neck 



^ This term having been applied by Waterhouse in 1842 to an African squiiTel, Dr. Gray in the Ann. and Mag. 

 Nat. Hist. 1867, vol. xx. p. 278, re-named the Celebes 'squirrel as S. schlegelii, a term afterwards suggested by A. M.-. 

 Edwards (Rech. des Mammif. 1871, p. 163) for the same reason, he being unaware that Dr. Gray had anticipated him. 



2 As far as possible, I have personally examined the type of each supposed species, and the only forms which have 

 not been seen by me are 8. redimitus and 8. rafflesi.
