narrow orbital rings are little conspicuous, very different to 

 the broad and conspicuously contrasted rings o£ halstoni. 

 Ears dark behind, their inner surface and the area round 

 their bases dark clay-colour. Hands and feet grizzled grey. 

 Tail throughout nitlch more suffused with dark buffy tlian in 

 madiircB, the under surface, instead of being only buffy at its 

 base, dark buffy for its whole length, \s\\ile even on the upper 

 surface a strong suffusion of tlie same colour is perceptible, 

 the hairs being ringed with black and buffy instead of black 

 and grey as in the allied form. 



Dimensions of the type (measured in the flesh) : — 



Head and body 198 mm. ; tail 187; hind foot 43 ; ear 91. 



Skull: greatest length 47'3; condylo-incisive length 43; 

 // to m^ 9.

Considering the local plasticity of S. notatus, it is quite 

 natural to find tiie Bali representative cf the group distin- 

 guishable from the Maduran and from both the Javan forms 

 of the species. Curiously enough, this animal is almost more 

 similar to the typical S. notatus of Buitenzorg than to the 

 geographically nearer subspecies madurm, but is readily 

 distinguishable by its more buffy colour and especially its 

 more ochraceous under surface. 



Mr. Stresemann tells me that he found this squiryel very 

 common in Bali. 



Ratvfa bicolor haliensis, subsp, n. 



Like true Javan bicolor, with the following exceptions : — 

 Park colour of the forearms not passing up oii to the 

 shoulders, the blackish shoulders beijig a very marked 

 character in all the specimens seen of bicolor. Back drabby 

 creaniT-colour, paler than in any bicolor, but how much this 

 colour is the result of bleaching cannot be stated 5 it is, 

 however, paler than the most bleached part of the back of 

 bicolor, and matches the pale colour of the crown. Under 

 surface more brightly buffy than in most B, bicolor. Feet 

 with the buffy metapodiaV markings at a minimum. Tail- 

 hairs with their buffy ends hardly more than one-.third the 

 length of their dark basal portion, while in bicolor the two 

 portions approach equality. 



Skull as in true bicolor, its size much less than in B. bicolor 

 major, Miller.
