Type (by monotypy): Columba humeralis Temminck. 
Medium Doves with slender bills, long wings, long wedge tail and short legs 
and long toes. The bill is comparatively long and slender, the dertrum short and 
decurved with a forward direction, tip not hooked, nor the dertrum swollen ; the 
culmen ridge is flattened for more than half its length, the linear nostrils overhung 
by a swollen membranous delicate operculum not expanded at the base; the 
lower mandible has a short semi-angulated gonys, the rami long and obsoletely 
grooved, the narrow interramal space feathered. The wing is long with the first 
primary shorter than the sixth, the second equal to the fifth and the third longest ; 
the secondaries are comparatively long and the first primary has the tip abruptly 
attenuated for about one-third the length, the outer edge a little scalloped; the 
fourth and fifth primaries show a little scalloping on the outer edges but none, 
except the first, show any on the inner edges. The tail is long and strongly wedge 
shaped, almost as long as the wing; the feathers are fourteen in number, with 
rounded tips, fairly broad, the outer ones about two-thirds the length of the central 
pair. The legs are short and unfeathered, the tarsus being little longer than the 
culmen and about the same length as the middle toe; the front of the tarsus is 
covered with regular broad horizontal scutes, the sides and hind portion having 
an unbroken skin; the toes are regularly scaled, the middle toe longest, but not 
abnormally so, the inner and outer subequal, the claws long but the mid-claw not 
extraordinarily elongated ; the hind-toe very long and straight and without much 
lateral skin expansion. 
Coloration brownish above with black tips to feathers, fore-head and breast 
bluish-grey, abdomen whitish, tail brownish with white tips to outer feathers.
