SULA DACTYLATRA PERSONATA Gould.
Five adults, both sexes, Tubbataba Reef, Sulu Sea, August, 1913.
The Blue-faced Booby, which breeds in the Tubbataba Reef in the Sulu
Sea is indistinguishable, so far as I can see, from the Australian
form.
The color of the bill and feet was not noted on the labels of Gov.
Forbes's birds; in the dry specimens the bill is pale yellow and the
feet are dull greenish black.
