Syrrhaptes Illiger, Podromus, p. 243 (1811).
Type, Tetrao paradoxa Pali.
The genus Syrrhaptes is distinguished by having no hallux and by having the very short squat toes feathered above to the tips as well as the whole of the tarsus; the central tail-feathers are greatly lengthened as in the Pin-tailed Pterocles ; the wing is long, with the first primary much the longest. Two species are known which are purely Asian but one of these makes curious irruptions into Europe having repeatedly occurred as far West as England.
