DistrilDution. — The eastern bank of the Rio Negro, a northern 

 tributary of the Amazon. Mr. Bates obtained a specimen 

 at Barra, where it was rather common in the forest; and, 

 he adds : " This place, a waterfall near Barra, which its citi- 

 zens consider as the chief natural curiosity of their neighbour- 

 hood, is classic ground to the naturahst, from having been a 

 favourite spot with the celebrated travellers Spix and Martius, 

 during their stay at Barra in 1820. Von Martius was so much 

 impressed by its magical beauty, that he commemorated the 

 visit by making a sketch of the scenery, to serve as background 

 in one of the plates of his great work on the Palms." 



He-bits. — Keeping together in small troops, running along 

 the main boughs of the loftier trees, climbing perpendicular 

 trunks, but never taking flying leaps.
