Genus ORE ih @i2 mes: 
ORBITOLITES 3 COMPLANATA Lamarck. 
Orbitolites complanata LAMARCK, Syst. Anim. sans Vert., 1801, p. 376. 
An inhabitant of shallow tropical waters, occasionally so abun- 
dant that it becomes an important factor in the building of tropical 
coral islands. Occurs rather sparingly at Stations D. 4000, H. 4476, 
and H. 4566. | 
ORBITOLITES MARGINALIS (Lamarck). 
Orbulites marginalis LAMARCK, Anim. sans Vert., II, No. 1, 1816, p. 196. 
Not quite so widely diffused as the species Orbitolites complanata, 
it is extensively found in warmer seas, and it is said by Doctor Car- 
penter to be more abundant where Orbiculina is rare, and the oppo- 
site. It obtained its maximum development in the early Tertiary, 
where specimens of enormous size and abundance are found. Not 
very common, but present at Stations D, 4000, H. 4476, and H. 4694.
