Vernacular names. None recorded.
Description. Differs from the preceding form in its bigger, coarser yellow bill and in having paler, greenish-blue legs.
Colours of soft parts. Bill yellow, never greenish; legs and feet greenish-blue.
Measurements. Culmen 103 to 114 mm.; wing 419 to 452 mm., nearly always over 430 mm.
Distribution. Australia, through the Austro-Malayan islands to the coasts of Indo-China and thence as a straggler to the Bay of Bengal.
Nidification. Macgillivray records the breeding of this Gannet in Raine Island on the 15th of July, on which date, however, there was but one egg laid. In the ' Emu ' he describes the nests as similar to those of other Boobies and invariably built on the ground. The egs:s are two in number and not distinguishable from those of other Boobies except by their size. When disturbed the birds shuffle off their nests and run a few paces, disgorging fish, before they rise on the wing.
Habits. Those of the genus.
