MAMMALS rnOM SIAM. 45 



from the mainland races and from Siamese island forms (Telibon, 

 Samui, Pennan, and Kut) by their deep ochraceovis-tawny under 

 surfaces and by the gi'eater amount of black on the inner side of 

 the hind limbs. 



Though the island of Koh Chang is larger than Koh Kut, 

 nearer to the mainland, and in much shallower water, no form 

 of Giant Squirrel occiii'S on it. Yet the Eatufa of Siam was 

 found immediately opposite the former, whereas all along the 

 coast in the vicinity of Koh Kut it was not met with.

6 males, 7 females, Ok Yam, Franco- Siamese Boundary; 



2 males, 3 females, Klong Yai ; 2 males, 1 female, Klong Menao ; 



3 inales, 2 females, Lem Ngop, S.E. Siam. 



The above specimens show a cei'tain amount of variation in 

 colour. On the whole, however, they most nearly approach 

 Sciurus sjdendens, var. 2 of Gray { = cinna'momeus Temm.). 

 " Top of head (and top of back by inference) and tail dark and 

 very intense red-bay ; side of the back, under sides of the body, 

 and tip of tail paler red-bay." A few approximate to var. 3. 

 " Uniform pale bay, like the side of var. 2 ; tail and middle of 

 the back rather darker and brighter ; tail without pale tip," 

 though the latter shows some .signs of " bleaching " at the 

 extremity. The majority of the collection have the sides of 

 the head grizzled greyish, and there are traces of grizzling on the 

 fore limbs : these latter features, together with an indication of 

 grizzling on the thighs, being most pronounced among the five 

 examples from Lem Ngop, the western extremity of the series. 

 Again, two or three approach var. 1, " all over dark and very 

 intense red-bay," except that they have no " white spot on each 

 side of the base of the tail." 



Measurements. — Ears of the series 19-23 mm. For other 

 measurements see table, p. 70. 



I do not know from what locality Temminck 's Sciurus cinva- 

 moineus came, and we have also no details as to the provenance 

 of the animals on which Gray founded his species, beyond the 

 fact that their collector, Mouhot, tiavelled widely in Siam and 

 Cambodia ; but it appears to me that when the Red Squirrel is 

 fully known over the whole of its range it will be necessary 

 to recognif-e several geographical races: to all of which the
