 Macroxus caniceps, Gray Ann. Mag. N. H. (3), xx, p. 280(1867). 



Distribution : — Tenasserim, from the Moulmein district in the 

 north through the Malay peninsula to Malacca, 



This species, like the other Burma squirrels, varies considerably ; 

 the specimens from about Moulmein, whence came the original 

 type of Sciurus chrysonotus, have the back suffused with bright 

 orange yellow during the breeding season, which takes place during 

 the cold months from October to February ; the specimens from 

 Mergui further south do not seem to undergo a seasonal change, 

 but have the sides of the neck instead of the back tinged with 

 bright yellow ; further south still the specimens from Perak have 

 only a slight tinge of orange on the back and no cheek patches, 

 and this form agrees very well with the specimen from Malacca, 

 the type of S. concolor.
