Ilab. Eastern Nokth America, from Hudson Bay southward, and west to the Great 

 Plains, straggling thence to Nevada and Washington ^. — Mexico, occasional in the 

 State of Puebla, and at Jalapa and Orizaba in Vera Cruz (Sanchez^ ^). 



The Passenger-Pigeon, which formerly had a very wide range in North America, 

 where it multiplied to such an extent that over a thousand captures have been recorded 

 in one year in the district of Michigan alone, has of late been so reduced in numbers 

 that its breeding is now mainly restricted to parts of Canada and the northern portion 

 of the United States, as far west as Manitoba and Dacota ^, where it nests in isolated 

 pairs instead of in communities as formerly. We have reason to believe that 

 E. migratorius wanders as far south as the tablelands near the city of Guatemala. 



The nest is a frail platform of sticks, and the eggs are usually two in number, both 

 male and female birds taking a share in incubation, 



Pam. PERISTERID-ffi. 



The members of this family are mostly Ground-Pigeons. They have the tarsus 

 longer than the lateral toes, which are equal to, or only slightly longer than, the 

 middle toe. 



According to Count Salvadori, seven subfamilies are included in the Peristeridse, of 

 which the Turtle-Doves (Turturinse), the Bronze-wings (Phabinae), and the Hackled 

 Pigeons (Calcenadinse) are Old-World forms, the rest being American. 



Subfam. ZENAIDIN^. 



The characters for the above-mentioned subfamilies are very slight, and the only 

 features selected for the separation of the Zenaidinae are the blackish, somewhat 

 metallic, spot beneath the ear-coverts and the metallic gloss on the sides of the neck. 



Of the four genera comprised in the Zenaidinse, one {Nesopelia) is confined to the 

 Galapagos Archipelago ; but the other three, Zenaidura, Zenaida, and Melopelia, are 

 represented within our limits.
