N. GYLDENSTOLPE, MAMMALS COLLECTED IN SIAM. 13 



black squirrel was only obtained in a single specimen during 

 my journey. Near Sriracha, a small village on the mainland 

 just opposite tbe island of Koh-Si-Chang, I once had the 

 good fortune to shoot a fine female specimen. The type loca- 

 lity for Sciurus nox is given by Wroughton to the sea-coast 

 south of Bangkok thus this squirrel seems only to be con- 

 fined to a very small area of land where it also seems to be 

 rather rare. 



This species is nearest to Sciurus germaini A. M. Edw. 

 from Pulu Condor (an island near the coast of Cochin China) 

 but is distinguished from the last-mentioned species by its 

 larger size. 



The skull of the specimen in my collection measures as 



follows.

13. Tamiops macclellandi kongensis Bonh. — Bon- 

 hote: Proc. Zool. Soc. 1901 p. 55. — Surely the most com- 

 mon squirrel met with on favourable localities in every part 

 of the country visited by the Expedition. It was, however, 

 much more abundant in the open dry forests and bamboo- 

 jungles than in the evergreen forests. When observed it was 

 always in pairs generally living in the highest trees where 

 they were busily searching for food. They were very diffi- 

 cult to detect among the luxurious vegetation, where they 

 were running with a very great speed, without showing any 

 signs of fear. 



Bonhote hat separated the race of Tamiops macclellandi 

 Horsf. which inhabits Siarn and described it under the name
