BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 533 
hardly apparent, when worn examples of 7. 1. albiventer are compared.” 
It is true that abraded albiventer are considerably less brownish olive, 
more grayish than birds in fresh feathering, but even in comparable 
specimens in fairly new plumage, the differences do not impress one as 
constant. 
Birds collected from March to June are badly worn; those taken in 
November, December, and January are much less so. 
HYLOCICHLA MINIMA ALICIAE (Baird): Northern Gray-cheeked Thrush 
Turdus aliciae Batrv, Pacific Railroad Survey, vol. 9, 1858, p. 217 (Illinois and 
Upper Missouri= West Northfield, Ill.) 
SPECIMEN COLLECTED 
lad. 9, Venezuela, Cerro Yapacana, Upper Orinoco, April 15, 1931. 
In identifying this bird as aliciae I am recognizing the Newfound- 
land birds as distinct from continental northern birds. The New- 
foundland birds are the nominate form, a browner race. 
HYLOCICHLA MINIMA MINIMA (Lafresnaye): Newfoundland Gray-cheeked Thrush 
Turdus minimus LAFRESNAYE, Rev. Zool., vol. 11, 1848, p. 5 (Bogoté, Colombia). 
SPECIMENS COLLECTED 
lad. 9, Brazil, S4o Gabriel, Rio Negro, Amazonas, January 16, 1931. 
lad. 9, Venezuela, Cerro Yapacana, Upper Orinoco, April 15, 1931. 
These birds have wing lengths of 97 and 98 mm., respectively, and 
are therefore too large for the southern race bicknelli but fit within the 
variational limits of the nominate subspecies.

In birds from northern Venezuela (Ocumare de la Costa, La Trilla, 
Independencia, and near Maracay) Wetmore found the feathers 
behind the nostrils to be whitish (Proc. U. S. Nat. Mus., vol. 87, 
1939, p. 242). This is not true of the present series.
