tertials ; secondaries short. Tarsus shorter than the middle toe and claw, but longer than the 
lateral; scutellate anteriorly. 
Melopelia. —Tail short, rounded ; orbits naked. 
Zenaida. —Tail short, rounded ; orbits feathered. 
Zenaidura. —Tail excessively lengthened, cuneate, of fourteen feathers ; orbits naked. 
Chamaepelieae. —Size very small. Secondaries lengthened. Tertials nearly as long as 
primaries. Primaries dark chestnut internally. 
Chemaepelia. —Tail short, rounded. 
Scardafella. —Tail very long, cuneate. 
Starnoenadeae. —Legs very stout; tarsi decidedly longer than the middle toe, covered ante¬ 
riorly with small hexagonal scales or transverse scutellae. Wings short, very broad, and much 
rounded. Tail short, very broad.
