It is, however, impossible to recognize the two forms as specifically distinct. The range of the Common Kingfisher extends across the Palaarctic Region from the British Islands to Japan, but does not reach further north than about latitude 55°. To the south it includes the Canary- Islands, Egypt, India, China, and the islaufls of the Malay Archi- pelago. The Eastern form was described as a distinct species as long ago as 1788 under the name of Alcedo henyalensis (Gmelin, Syst. Nat. i. p. 450), but it is scarcely probable that any one would claim specific rank for it now. Suborder XI. CORACI^.
