in the dredgings. It is somewhat surprising that O. duplea 
should be altogether wanting in these foraminiferal deposits.

It is unusual to meet with this species in low latitudes, but it 
has already been recorded by Goés from the Pacific and the 
Caribbean Sea; and by Flint from Cape Hatteras and the Gulf 
of Mexico. 
The specimens from Funafuti lagoon exhibit the primordial 
segment, and the test is yellowish brown and composed of very 
slender and minute calcisponge-spicules.

This is one of the most characteristic and widely spread 
organisms both of the lagoon and the outer reef. It is an attached 
form, and makes its growth usually upon the fronds of Halimeda, 
but is also found growing upon other objects which present a 
suitable surface for the purpose.
