CRISTELLARIA ORBICULARIS (d’Orbigny). 
Robulina orbicularis D’ORBIGNY, Ann. Sci. Nat., VII, 1826, p. 288, pl. xv, 
EAS, 3, Y, 
Differs from Cristellaria vortex in its flange, or keeled border. 
West Indies, 450 fathoms, numerous localities in the South Pacific, 
and fossils in the Sub-Apennine of Italy and the Vienna Basin 
Miocene. Rare at Station H. 4508. 
CRISTELLARIA ROTULATA (Lamarck). 
Lenticulites rotulata LAMARCK, Annales du Mus., V, 1804, no. 3, p. 188; 
Tab. Encyel. et Method, pl. ccccnxvi, fig. 5. 
This species is the type of the group and is probably the most 
generally distributed and at greater variety of depths than any form 
of the genus. Its geological history is also long and dates from the 
Upper Trias of Derbyshire, England. Not uncommon at Station 
D. 4000 and present at H. 4430. 
CRISTELLARIA VORTEX (Fichtel and Moll). 
Nautilus vortex FICHTEL and Motu, Test..Microse., 1803, p. 33, pl. 1, figs. 
di. 
Chambers very long and narrow and separated by exceedingly 
curved septa, which sweep backwards a long portion of the shell. 
Test moderately vaulted and umbonate. Mentioned by Brady from 
four stations in the South Pacific, 125 to 420 fathoms, and off Ber- 
muda, in North Atlantic, 435 fathoms. Parker and Jones record the 
species in the Mediterranean, 90 to 360 fathoms. Flint mentions it 
from the Caribbean. Observed only at Station H. 4508. It 1s known 
as a Tertiary fossil.

POLYMORPHINA AMYGDALOIDES Reuss. 
Polymorphina amygdaloides Reuss, Sitazungsber. Akad. Wiss. Wien, XVIII, 
1855, p. 250, pl. vir, fig. 84. 
A depressed variety of the more common species Polymorphina 
lactea. Occurs rarely at Stations D. 4017, D. 4174, and H. 4567. 
POLYMORPHINA ANGUSTA (Egger). 
Globulina angusta EXacrr, Neues Jahrb. fur Miner., 1857, p. 290, pl. xtI, 
figs. 138-15. 
We find what appears to be a variety of the above species at Station 
4017. The form is of wide distribution, and while known in shallow 
dredgings is usually found at considerable depths. Iossil in the 
Bavarian Miocene. 3
