Chlamydotis Lesson, Rev. Zool., 1839, p. 47 (Feb.-March 1839).
Type by in on., Otis houbara Gmelin.
The genus Chlamydotis is separable from all other genera of Bustards by the presence of a curious crest of isolated feathers thinly webbed at the base; there is a ruff in both sexes on either side of the neck and the feathers of the lower neck are also lengthened.
The sexes are alike, the female being rather smaller.
There is but one species, Chlamydotis undulata, of which the typical form is found in Northern Africa and an Indian race, C. u. macqueenii, which breeds in Central Asia.
