bably all or, at any rate, the greater part of these species (except, 
perhaps, T. ncevius ) as winter migrants, and on the western 
coast T. flavirostris, while T. pinicola inhabits the pine ridges of 
Southern Mexico. Three other species (T. infuscatus, grayii , and 
assimilis), which I have placed under the head of Mexico in my 
list in the c Proceedings/ belong, I believe, to the tierra caliente 
exclusively, and must be set down to the account of the Neo¬ 
tropical region. 
The Thrushes of the Nearctic region may therefore be esti¬ 
mated as twelve in number; viz.—

If we exclude from the Neotropical region Turdi migratorius ,

the north, we shall find left about twenty-seven species, distri¬
