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

 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.
