Superfamily Ibidoide^. 



Family IBIDID^. 

 Subfamily Ibidin^^, Ibises. 



The status of the genera composing the subfamily Ibidince is by no 

 means yet satisfactorily settled. As our material is very small, we 

 shall not attempt to solve the question here. The apparent difference 

 between the two species inhabiting Japan is so great, however, that we 

 prefer to regard them as generically distinct until Ave have had an oppor- 

 tunity to convince ourselves that the differences are bridged over by 

 some of the forms unknown to us. 



The two genera may be distinguished as follows : 



o' . Face only bare of feathers Xipjionia. 



O'. Entire head and neck naked Ibis.
