 of a yellowish or orange colour. The only speci- 

 men known was brought from Borneo, and had 

 not grown to the size of the Bruang, being 3 feet

 making, with the head on the ground, antics as if it 

 ivould stand upon it; and was killed by its own 

 gluttony.

 M. Blainville considered them to have been extracted, 

 and, therefore, named the species a true bear, " Ours 

 Batteleur," or Tumbler Bear; but it appears that 

 there are at any time only four incisors above, and 

 the six below have commonly the two middlemost

 the nose is extensile and moveable, and the lips are 

 protrudable. Beside these characters, the ears are 

 narrow, small and pointed, and there is a profusion
