able characteristics of this Globigerina. Professor Brady does not 
mention it as a pelagic organism and believes its distribution to be 
very limited. Found rather frequently at some stations and present 
at H. 4174, H. 4440, 4585, H. 4566, H. 4571, H. 4585, H. 4590, and H.

GLOBIGERINA DUBIA Egger. 
Globigerina dubia Beaerr, Neues Jahrbuch fiir Min., 1857, p. 281, JO, I<, 
figs. 7-9. 
“The Globigerina dubia of Egger can only be accepted as a va- 
rietal modification of Globigerina bulloides, representing perhaps 
the best development of the typical characters. The test attains 
somewhat larger dimensions, is stout and compactly built, distinetly 
rotaline in general conformation, and with a well-marked umbilical 
cavity. It has frequently as many as fourteen or fifteen segments. 
Pelagic specimens of this variety have been taken in the South 
Atlantic and in the North and South Pacific; and in bottom ooze 
it has been found also in the North Atlantic. Its northern limit 
appears to be about latitude 56” north, a little to the south of the 
Roekhall Bank; whilst in the opposite hemisphere it reaches as far 
as about latitude 46° south in the Southern Ocean.” « Doctor Egger’s 
fossils were from the Miocene of Bavaria. Obtained at Stations 
D. 4174, H. 4480, H. 4502, H. 4508, H. 4555, H. 4566, H. 4568, and 
H. 4571. 
GLOBIGERINA HELICINA d’Orbigny. 
Globigerina helicina D’ORBIGNY, Ann. Sci. Nat., VII, 1826, No. 5, p. 277. 
Reported to be rare in both the North and South Atlantic and the 
South Pacific. Jknown as a fossil in the Italian Tertiary. Rare and 
found only at Station H. 4696. 
GLOBIGERINA RUBRA d’Orbigny. 
Globigerina rwbora D’OrRBIGNY, Foram. Cuba, 1889, p. 94, pl. Iv, figs. 12-14. 
Most abundant in Tropical oceans. Rather less common in our ma- 
terial than other Globigerinw and found at all stations save D. 4000, 
H. 4440, H. 4508, H. 4555, HW. 4571, and A. 4590. 
GLOBIGERINA SACCULIFERA Brady. 
Globigerina sacculiferad BRaby, Geol. Mag., Dec. 11, IV, 1877, p. 535. 
Next to Globigerina bulloides this is the most abundant species of 
the genus Globigerina in our material, and we find it very plentiful 
and present in every station except H. 4585. Its range is similar to 
that of G. conglobata.
