90 NATURAL HISTORY. 
therefore, agreeably to our former practice, we introduce at 
the conclusion of the European birds. 
The Coly genus includes about five species of foreign 
birds, much resembling each other in character and manners. 
As a specimen we have selected the White-bached Col), which 
is an inhabitant ol the Cape of Good Hope. It is in length 
twelve inches. The general colour of the plumage is bluish 
asli-colour ; the head is very full crested ; the under parts of 
the body are whitish, and a stripe of pure white runs the 
whole way down the middle of the back. The tail is uniform, 
and ol an immense length. 
The Tanageii has been called the red-breasted black- 
bird, and the greater bulfinch. The genus includes about 
forty-five species. They are in general about the size of the 
canary bird, and vary in plumage according to the species 
and the climate. They bear much relation to the bulfinch, and 
are found in all the warm climates of America, north and 
south. 
As the last species bears a resemblance to the bulfinch, so 
the Man a kins may be said to bear some relation to the tit- 
mouse. I h ey vary, however, from the size of a pigeon, to 
that of a small wren. The Rock, or Crested Manakiti, is 
about ten inches long. The general colour of the plumage 
is orange, and the head is 'covered with a beautiful double 
crest. This species inhabits Surinam, Cayenne, &c. It makes 
its nest of a few dry sticks. They are in general shy ; but are 
sometimes rendered so tame, that they run along with the 
poultry. 
The Gold-headed Manakin is in the other extreme, being 
only three inches and a quarter long ; but it is a most beau- 
tiful animal. The head and neck are of a fine golden orange, 
and the rest of the body, wings and tail, are of a purplish 
black.
