A SMALL COLLECTION OF MAMMALS FROM CAMBODIA. 101 



dicated; pale stripes buffy, sides between them a grizzle of black 

 and brown ; under parts white suffused with buffy, strongly on 

 abdomen and thighs. 



Practically a topotype. 



5. Tamiops macclellandi dolphoides, subsp. nov. 



2 $ ad., KompongSom Bon, near Sre - Umbel, S.W. Cambodia, 

 21st Dec. 1918 [Nos 2723, 4/CBK.]. Dr Malcolm Smith's collector. 



Like T. m. rodolphi (A. M.-Edw.) of Eastern Cochin-China 

 but paler, less richly coloured throughout except for the tail which 

 is similar. 



The upper parts, including the yellow stripes, less suffused 

 with ochraceous or tawny, the hands and feet paler buff. Under 

 parts and inner sides of limbs antimony-yellow instead of ochraceous- 

 orange : lips and chin whitish buff. 



The interruption across the shoulders of the outer pair 

 of pale stripes distinguishes this animal from the form occurring 

 in South Eastern Siam.* 



Type. No. 2723/CBK. 



I have ventured to name these examples, though they may 

 only represent a seasonal colour phase of T. m. rodolphi ; but I do 

 not think that animals from so far south in the Indo-Chinese Penin- 

 sula undergo such a change of colour.
