Affinities. To some of the genera in the next sub-family this genus presents an affinity in 

 the form of the hind toe, which, though not strictly lohated, is thickened on its lower side. '1 he 

 trachea presents considerable affinity to both the sub-family we have placed it in, and also to ihc 

 following. The bulb at the inferior larynx much more osseous on its external aspect than among 

 the Fuligulina, and less so than among the Anatince : it is also laterally much compressed, as in 

 the following sub-family.
