Juan del Rio. . 
Two other names have been applied to this Thrush. That of Turdus rufopalliatus 8, 
given to it by Lafresnaye, was based upon a specimen said to have come from Monterey, 
California; but this, as Prof. Baird has already pointed out, is an erroneous locality. 
So also, probably, is “ Lower California,” quoted by Mr. Sclater in his “ Synopsis of the 
Thrushes of the New World”?. The name Turdus palliatus ®, used by Bonaparte, is 
simply a synonym of the present bird. 
Grayson, to whom Turdus flavirostris was well known, says® ¢ that it has the general 
appearance of Turdus migratorius, and that, like that bird, it is also partially migratory 
in its habits. It frequents the Tres Marias Islands in great numbers, and becomes ex- 
cessively fat upon the berries which they find there in abundance. It breeds on these 
islands, and is found equally commonly on the mainland. Grayson further describes it 
as an inhabitant of woods and as gregarious in its habits, and says that in its migrations 
it passes from one part of the country to another in quest of the different kind of berries 
which are its chief subsistence. 
The sexes of T. flavirostris are said to be almost alike. 
Our figure is taken from one of Xantus’s specimens from the Plains of Colima, 
which agrees with Swainson’s type still extant in the Cambridge Museum.

Dr. Hartlaub was the first ornithologist to describe this Thrush, from specimens 
obtained in Guatemala‘; it was soon afterwards figured by Vicomte DuBus in his 
‘Esquisses Ornithologiques’?; and from that time specimens of it have been occa- 
sionally sent to Europe by Constancia and others. 
Turdus rufitorques is rather local in its distribution in Guatemala, though its range 
extends over a considerable area in that country. It has, too, a great range in altitude,
