ON TWO NEW SQUIRRELS FROM THE 
INNER GULF OF SIAM. 
By C. Bopen Ktoss, F.Z.S. 
In January 1915 I paid a short visit to Koh Si Chang * in the 
Inner Gulf of Siam and at its conclusion (having no time to go on 
myself to the next island) sent my collectors to Koh Phai. 
Koh Si Chang has been regarded of late as the type locality of 
Seiurus finlaysoni, but in looking through the history of that name it 
becomes evident that this is a mistaken view and that it applies to the 
white squirrel of the Siamese mainland. 
Sciurus jfinluysoni was described by Horsfield in 1824 (Zoological 
iesearches in Java) irom specimens collected by Dr. George Finlayson, 
the naturalist who accompanied Crawford in his mission to Siam and 
Cambodia. It is evident that Horsfield, when erecting the species, had 
in mind the mainland animal, for he says that it is Buffon’s “ Kcuriel 
blanc de Siam” which was seen at Lonpeen, a village situated in the 
extensive forests of Siam, by P. Tachard in his travels. The account 
of the species closes with an extract from Finlayson’s manuscript 
describing the white squirrel which ends “ene of the specimens was 
shot by Lieut. Rutherford on the Islands called Sichang in the Gulf of 
Siam.” It is once more obvious that Finlayson, too, was dealing with 
the mainland animal and that this reference to the island example was 
merely a detail as to extent of range. 
Further Horsfield, in the Catalogue of the Mammalia in the Musewm 
of the Hast India Company, 1851, again gives the locality of a specimen 
of S. finlaysoni as Siam, while Anderson who personally studied all the 
types of what he regarded as varieties of Sciwrus ferrugineus states 
(Zoological Researeh in Yunnan, p. 244) that “the type of S. finlaysont 
was obtained in Siam by Dr. Finlayson and another was procured by 
the same traveller in Sichang Id.”
