new Insular Squirrels from Peninsular Stam. 121 
Callosciurus epomophorus pipidonis, subsp. n. 
Size smaller than in epomophorus and the colour paler 
throughout. Upper surface uniformly suffused with buffy, 
not so dark a grey as in epomophorus ; under surface with 
the rufous duller anteriorly and more ochraceous on the groin- 
patches. 
Hlab. Koh Pipidon, 7° 45’ N. 
Callosciurus epomophorus tacopius, subsp. nu. 
General colour above more suffused with fulvous than in 
epomophorus, especially along the shoulder-area. Below, 
this is even more strongly marked, the whole under surface 
more or less strongly ochraceous—the chest as usual least so 
and the inguinal region most, but there is only rarely a 
distinctly grey chest. A paler ochraceous postauricular 
patch. Ochraceous of belly running down to the heels. 
Hab. Koh Rah, Takopah, coast of Peninsular Siam, 
8° 50’ N. 
Specimens from a locality intermediate between this and 
Salanga, Tang Prang, Takuatung, 8° 35’, appear to be quite 
similar to true epomophorus, and again others from Delisle 
Island, further north, do not seem to have become definably 
specialized. 
Callosciurus concolor telibius *, subsp. n. 
) 
Size smaller than in the previous forms. Coloration very 
similar to that of Perak concolor, the back grizzled ochraceous 
tawny or cinnamon instead of the grizzled grey of the epomo- 
phorus series. No trace of reddish epaulets or warmer areas 
over shoulders, nor of ferruginous side, groin, or tail patches. 
Below dull greyish clay-colour, nearly as in lancavensis, not 
so clear a grey as in concolor, the usual darker median line 
present but not conspicuous. Hands and feet grizzled grey 
as in coneolor, but the hairs of the terminal phalanx of both 
fingers and toes buffy yellow. ‘T'ail with black end as in all 
the epomophorus group, its upper surface grizzled, with buffy 
tips to the hairs; its midrib below (short of the black tip) 
prominently buffy for its terminal half. 
Hab. Pulau Telibun, near the coast of Trang, Peninsular 
Siam, 7° 18’ N. 
In its possession of a black tail-tip this squirrel resembles 
* The accent being on the middle syllable of Telibun, the above seems 
the best name to indicate that fact.
