cot state, are to paler shades of blueish-grey, and 
to the extinction of the white on the rump ; vinous 
or reddish purple is a change not unfrequent, and 
here all the markings of the true state are kept 
up in darker and lighter shades ; white birds 
occur, and they are sometimes pied with black. 
Among the fancy breeds, now become very nume- 
rous, and receiving provincial names from their 
properties. The “ Tumbler ” and “ Carrier ” 
pigeons are remarkable, from the proportional 
shortness and length of their respective heads and 
bills, and where a deviation of structure from 
the original type is observed. Another remark- 
able deviation is in the “ Fan Tails ” and “ Broad- 
tailed Shakers," where the tail is displayed, and 
consists of numerous feathers, sometimes amount- 
ing to thirty-six in number. In the “ Jacobin ” 
the feathers are reversed, and turn over as a cowl 
on the back of the head and neck. In another, 
again, the tarsi become feathered, and in the 
extreme of this variation, the plumes are length- 
ened, and stick out in the form of little wings. * 
The Turtle Doves or Pigeons of which we possess 
a single migratory example, are all of a smaller 
and more slender proportion than the true pigeons, 
and the tail is much graduated. They are thus 
characterized.
