Confined to warm portions of America and Africa. Formed 
of but two species, differing from each other as the subgenus 
Holopodius from the other Phalaropodes. Anomalous: buffet- 
led about in different Families, and even Orders. Whatever be 
its artificial character, its natural station is undoubtedly next 
to Plotus, as is evident from its form, habits, and especially 
its skeleton. The digital membrane is so deeply indented, 
as to give rise to some doubt whether it exists ; but the cha- 
racter, though almost obsolete, is still preserved.
