 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 

 9 inches in length. In manners this animal is most 

 likely quite similar to the former. The indivi- 

 dual which existed in the Tower of London, stood, 

 however, with more facility on his hind feet, pro-

 are still more characterized in the next species, 

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

 would 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

 narrow, small and pointed, and there is a profusion
