MiDiimals from the JuJiore Archipelago. 593 



Remarks. — Though Pulau Dayang is separated from 

 Pulau Aor by a channel which is little more than a quarter of 

 a mile wide, there is a minimum depth of twenty-five fathoms 

 between the two islands, and it is unlikely that any inter- 

 communication can take place between the races of squirrels 

 and rats found on either side of the strait. The ten speci- 

 mens from Pulau Dayanoj when mixed with thirty from 

 Pulau Aor can be picked out without the slightest difficulty 

 by any person able to appreciate marked differences in tint. 

 The affinities of the present form and Sc. v. tenuirostris 

 inhabiting Tionian are decidedly with the mainland races, 

 while those of Sc. c. aoris and *S'c'. v. pemangilensls are rather 

 with those inhabiting the Natunas and Anambas.

 at the base of the vibrissoe, which are dark brown, paler at 

 the tips. Hands and feet whitish, without darker stripe, 

 sharply defined in the case of the feet from the colour of the

 arms to the ankles and wrists. Tail black above and at the 

 tip, whitish beneath.
