We have collected the following remarks on the distribution of 
this species: Australia and Polynesia: north and northeast coast of 
Australia (McGillivray) Torres Strait (Gould), New Caledonia (Forster, 
Verreaux), Tonga Islands, Lord Howes Island, Society Islands, Huaheine, 
Oriadea (Forster), Endery Island (Gray), Bonin group (Kittlitz), Viti Is¬ 
lands, Samoa Islands, McKean Island, Phoenix group (Gr&ffe), Kingsmill 
group, Gilbert Island, Paumotu group, Aurora Island (Peale), Marquesas, 
Palmerston and Christmas Island (latter indications according to Gray). 
D. sula breeds on most of the coral islands of the Pacific (accord¬ 
ing to Peale), as well as in the areas of central Polynesia to be dis¬ 
cussed by us, for Dr. Gr&ffe sent eggs from McKean Island. 
The egg, collected by Dr. Griffe on McKean Island, Is oblong, 
asymmetrical, clearly pointed at the narrow end and of a light greenish- 
bluish color. This latter color is first in evidence when one removes 
the dull, yellowish-white covering with a knife. This chalky covering 
does not cover the egg evenly, but is so thin in places that a bluish 
coloration shows through. In other places it seems particularly thick 
and forms marked protuberances containing marks which at least in a fresh 
state occurred during laying. Also under external influences the egg 
has a rusty yellow coloration toward the end. Length 2"! 1 ", width l n 6 ttT . 
D. sula may also breed along the African coast; the Leiden Museum possesses 
a speciman collected in August on the Gold Coast. 
Cassin's attempt to divide the great Frigate Bird into two species, 
an Atlantic (T. aquilus) and a Pacific (T. Palmerstoni) has proven to be 
quite untenable, since the characteristics which Cassin gives for the 
Palmerstoni, such as "larger throat sack, narrower primaries and tail 
feathers, longer tail and smaller size,” are far from constant and must 
be ascribed to chance deviations. Between skins from McKean Island and 
Brasil we have not found the slightest support for a species differenti¬ 
ation. It is also unjustified for Cassin to assign the smaller birds to 
T. Palmerstoni Gml., since Latham indicates a larger size for these than 
for aquilus.
