BIRDS — COLUMBIDAE. 
601 
Sub-Family ZENAID1NAE. 
Ch. — 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 14. 
This sub-family is readily distinguished from the preceding by the longer and more denuded 
tarsi, the feet much better fitted for a terrestrial life. The following sections belong to it : 
Zenaideab. — Size moderate. Wings lengthened, acute ; primaries much longer than the 
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. 
Starnoenas. — Legs very stout ; tarsi covered with hexagonal scales.
