Any one of numerous species of birds belonging to Turnix or Hemipodius and allied genera of the family Turnicidæ. These birds resemble quails and partridges in general appearance and in some of their habits, but differ in important anatomical characteristics. The hind toe is usually lacking. They are found in Asia, Africa, Southern Europe, the East Indian Islands, and esp. in Australia and adjacent islands, where they are called quails (see Quail, n., 3.). See Turnicimorphæ.  [1913 Webster]
