9. SCIURUS CONCOLOR SAMUIENSIS. 



Bobi)iso7i and Kloss, torn, cit., p. 226. 



Koh Samui, 40 examples. 



Occurrino- in enormous numbers in the coconut o-roves of the 

 island and causing very serious damage to the crops. Also m.et with, 

 though much less numerously, in the primaeval jungle in the centre 

 of the island. 



Ther-e is little doubt that this race is very markedly distinct 

 fi-om all the mainland races of Sc. concolor, occurring on the 

 Peninsula itself and also from all the island races adjacent to our 

 area, with the possible exception of 8c. c. epomophoriis from Salanga 

 (Junk Ceylon), from which race it is apparently distinguished 

 by the more oclireous colour of the shoulder and thigh patches, 

 which are " hazel " in the Salanga form. The degree of brilliance 

 of the very large series before us, all collected within a period 

 of three weeks, varies very greatly and the most ornate approach 

 that form of the Tenasserim 8c. concolor caniceps known as 

 8c. concolor chrysonottis, from which they may be differentiated by 

 slightly smaller size and darker colour beneath. 



It is possible that the whole series has been collected during 

 a period of transition between a normal breeding pelage and one 

 of "eclipse'' tliough there is no direct evidence i hat such occurs 

 in any member of the Scixiridx, found south of the Isthmus of Kra.
