4 Hydrocorax. 



Mange of the Genus. 

 Oriental Region. 



Mange of the Species. 



1. Hydrocorax planicornis. Luzon, Philippine Islands. This species was always stated by 

 the older writers, and even, among modern ones, by as good an authority as the late Mr. Blyth, 

 to be an inhabitant of the Moluccas. It has, however, comparatively lately, been ascertained to 

 be a native of Luzon in the Philippine archipelago ; and from that fact it is assumed that it is 

 not found on any of the Moluccas. So far as known at present, the species seems to be restricted 

 to the island named above.

3. Hydrocorax semigaleatus. Leyte, Philippine Islands.
