Besides this, in the same country is found the genus Ceri- 

 ornis, or Tragopans, which also would bear our climate per- 

 fectly well. 



The next genus in value, as well as order, is that of Melea- 

 gris, or Turkeys. There are but two species, however, belong- 

 ing to this genus, one of which is found in the north, and the 

 other in Central America. M. gallopavo is the common North 

 American species, which has been spread all over the world. 

 The other species, M. ocillata, was almost unknown, until 

 within a few years. It is much more beautiful than the common 

 turkey, and also much more delicate and difficult to rear ; so that 

 I doubt whether they can be successfully domesticated in this 

 country, though they are not uncommon in a domestic state in 

 Yucatan. I started from the port of Sisal with three living 

 specimens, which were unfortunately lost overboard in the 

 Gulf of Mexico. 



I understand that the Earl of Derby had some at Knowsly 

 Park, but I doubt whether they are still living. 



Next in order is the genus Numida, or Guinea fowl, of 

 which there are five known species, all natives of Africa ; only 

 one species is domesticated, viz., N. meleagris, or common 

 Guinea fowl. 



Besides the birds already mentioned, we might add the 

 splendid Lopophorus, or Monaul, from the Himmaleh Moun- 

 tains ; the Tetraogallus caucasicus, and the Pacrasia macro- 

 lopha, all from the same region ; also, our Tetrao cupido 

 Grouse, or Prairie hen ; the Tetrao urogallus, or Cock of the 

 Woods, and the Tetrao tetrix, or Black cock of Europe. 



From the order Columbae are derived some species of 

 considerable importance to the poulterer. All the principal 

 varieties of pigeons come from the genus Columba, species 

 livia, or rock-pigeon of Europe, which, in the wild state, 

 breed in the sides of rocky islands, as the Faroe Islands, and
