_Hesperocichla_, BAIRD, Rev. Am. Birds, I, 1864, 12. (Type _Turdus
nævius_, GM.)
[Line drawing: _Turdus nævius._
9814]
The single species of this subgenus differs in form from the Robins
(_Planesticus_), in the more awl-shaped bill, the curved commissure,
and the absence of a notch at the end; the longer, slenderer, and
straighter claws; and in the dissimilarity in color of the sexes. In
the latter respects it agrees with _Merula_ of Europe and Middle
America; in which, however, the bill is distinctly notched, and less
attenuated. The tail is shorter and broader than in _Planesticus_,
more as in true _Turdus_ or _Hylocichla_.
