The hind-toe is the only one which has the skin of the sole somewhat expanded 
on the sides. The nostrils are linear and quite or nearly parallel to the edges 
of the tomia or upper mandible. The bill is straight at the base, somewhat 
compressed, the point deflexed, but not hooked. Metatarsus rather short, 
feathered only on its uppermost part. Wings long and pointed, the first primary 
not abruptly attenuated and longer than the sixth, the second generally longest, 
but sometimes the second and third, or the first and second. Tail not longer 
than the wing, with twelve rectrices, nearly even, or rounded, but not graduated. 
This genus, as limited by Count Salvador! {Gat. B. Brit. Mus., Vol. XXI.), 
and generally accepted, contains more than seventy forms, some of which are, 
however, only slightly differentiated geographical races. 
The genus is distributed over nearly the whole surface of the earth, but only 
one species occurs in Australia.
