THE BIRDS OF AUSTRALIA. 
Fig. A, the tarsus of F. grallaria is shown as booted. This is strange, as the 
majority of his specimens were F. g. segethi, which has the tarsus scutellated. 
When Ridgway introduced his new genus Cymodroma, he noted “ claws very 
broad and flat, somewhat <3^ " s^i^'Ped.” This is not so distinctive of 
F. leucogaster or tropica, the typical species of his genus, as it is of 
F. grallaria. 
To review : F. grallaria is distinct from F. leucogaster, and the former occurs 
from Australia eastwards to the west coast of South America, and the latter 
from Tristan d’Acunha, or thereabouts, to the South Indian Ocean and north- 
wards to Florida. 
Fregetta grallaria Vieillot must be erased from the American O.U. 
Checkhst, and in its place must be reinstated Fregetta leucogaster Gould. 
Inasmuch as the type of Fregetta lawrencii Bonaparte {Comptes Eendus 
Sci., Paris, Vol. XLII., p. 769, 1856) is lost, that name must be ignored, 
as there is nothing in the diagnosis whereby it can be separated from 
F. leucogaster Gould.
