for series the Trengganu animals are a trifle duller—i.e., the top and 
sides of head are greyer, the ring round the eye is paler, and the orange- 
tawny suffusion of back and tail is less intense. 
10, SCIURUS (VITTATUS) MINIATUS, MrirtueEr. 
Bukit Jone. 12g; 129. 
Coast of Trengganu, 
A typical series, indistinguishable from Trang (type locality) and 
East Coast animals. 
I. SCIURUS (NIGROVITTATUS) BILIMITATUS, Miner. 
Coast of Trengganu. 2 specimens, 
One of these, a female from Tanjong Laboha, is the type. The 
race extends across the Peninsula to Upper Perak and goes northward. 
12, SCLURUS TENUIS, Horsr. 
Bukit Jone.. 75; 32. 
Coast of Trengganu. 
I have carefully compared the Bukit Jong series with a series of 
topotypes from Singapore. None of that dulness of pelage, which 
S. tenuis exhibits towards the northern extreme of its range, is 
traceable. On the contrary, the Trengganu series is more ochraceous 
than the Singapore collection, especially as regards the under surface of 
the body ; the under parts of three males in particular being unmatch- 
ed for depth and spread of that colour, while the abdomens of the 
remainder are decidedly more buffy, but the skulls and teeth do not 
differ appreciably. 
Sciurus tenuis surdus, Miller,* was described from Trang examples, 
but, owing to the fact that until lately we had seen no topotypes, while 
the authorities of the United States National Museum had sent 
us specimens from Johore under that name, thus, apparently restricting 
the typical tenuis to Singapore Island, we had been unable to regard 
the race as valid.t We have recently, however, obtained a series of 
topotypes, and I am now prepared to accept Miller’s race as distinct. 
It is confined, however, to the more northern parts of the Peninsula, 
though of course connected with Sciurus tenuis typicus by many 
intermediate animals, but, however indefinite many of these latter may 
be, by no means all individuals from the mainland must be placed 
under Miller’s sub-species as I have shown above.
