Five examples of tliis very variable squirrel were given me by 

 H. II. H. the Prince of Cliumpon. They all came, I believe, from 

 Bangkok, and I will describe them ver}' shortly to show how greatlj'' 

 the form differs within itself: unfortunately the dates at which they 

 were collected have not been recorded. 



No. 2515. d ad. Occiput, nape, back, and basal half of tail 

 above, black, very finely and slightly speckled with white in places ; 

 the black extends narrowly down the middle of the upper part of 

 the forelimbs and more broadly over the thighs : crown and distal 

 half of tail above mixed black and white. Remaining parts white. 



No. 251G. d ad. Like 2515 but rather more speckled with white 

 above. 



No. 2517. 2 inun. Disposal of colours as in 251(5 but back, 

 etc., brownish black finely speckled with rufous : distal three-fourths 

 ot tail banded black and rufous throughout with a few white hairs near 

 the tip. Remaining parts white. 



No. 2518 <S ad. Above ferruginous annulated with black ; 

 underparts rufous (burnt sienna) ; tail proxunally ocliraceous and Ijlack, 

 distally mahogany red 



No. 2519, 9 ad. Like 2518 but practically without black on 

 the head, fore-limbs and ankles and with the mahogany reil of the tail 

 extending along the lower surface to the root. 



The last pair have smaller skulls and teeth than the first two 

 specimens but all obviously belong to the same form and are connected 

 by the intermediate example from Sam Kok (antea, p. 17) which has 

 the speckled back of the latter animals and the white muz/le, ears 

 and underparts of the others. 



For measurements see p. 313.
