SUBFAMILY ZENAIDINÆ.

CHAR. Tarsi stout, lengthened; always longer than the lateral toes, and

entirely without feathers; the tibial joint usually denuded. Tarsus

sometimes with hexagonal scales anteriorly. Tail-feathers sometimes

fourteen.

This subfamily is readily distinguished from the preceding by the

longer and more denuded tarsi, the feet being much better fitted for a

terrestrial life. The following sections belong to it:—

=Zenaideæ.= Size moderate. Wings lengthened, acute, the primaries much

longer than the secondaries. Tarsus scutellate anteriorly. A blackish

spot beneath the auriculars; tail-feathers tipped with white, and with

a blackish subterminal bar. Sides of the neck with a metallic gloss.

Bill lengthened, much depressed. A white patch on the wing; no black

spots on the scapulars; plumage ashy, lighter beneath. Tail of

twelve feathers, rounded …

_Melopelia._

Bill smaller, more compressed. No white patch on the wing; scapulars

with black spots. Above olivaceous, beneath vinaceous.
