SOME SIAMESE MAMMALS. 8$ 



In many animals tliere is an extension of the white, which in its 

 fullest degree covers tiie upper sides of the forearnis to tlie wrists, and 

 partly covers the hands and also the hind feet, while sometimes the latter 

 and the elbows are partially blackened : but as the different colour 

 pat terns are not confined to separate areas they are not subspecific. 



The Patani specimen illustrates the increase of white to a full 

 degree. Mr. Aagaard assures me that it was a truly wild squirrel shot 

 near Bangnara, and therefore it forms a very interesting e.xtensioii of 

 the range of this race which we have hitherto known only from Johore, 

 Negri Senibilan and South Pidiang and have regarded as confined to 

 the southern extreinitj' of the Malay I'eninsula. 



I have already noted the apparent fact that some southern races 

 of animals are slower to change on the east side of the Peninsula tiian on 

 the west' but this is the most pronounced instance 1 have met with.
