Brady in the Challenger report includes numerous localities in the 
North and South Pacific and the South Atlantic, and the form is 
present in the Mediterranean. Its geological history dates from the 
Miocene. Found by the Albatross at Stations H. 4440 and H. 4694. 
CASSIDULINA SUBGLOBOSA Brady.

* Test subglobular, somewhat compressed on the two lateral faces, 
inequilateral; segments few, slightly inflated; alternation irregular. 
Aperture an oblique or nearly erect loop-like sht on the face of the 
projecting terminal segment.” * Essentially a deep-water species, 
the above is known from all the large oceans, but the localities are 
not very numerous. Found at three Albatross stations, namely, H. 
4430, H. 4571, and H. 4585. }

The genus “hrenbergina is closely related to Cass¢dulina, but dif- 
fers in the arrangement of the biserial chambers and less inrolled 
growth. Cassidulina has the segments both biserial and convolute, 
and resembles a bolivine shell longitudinally folded and then rolled 
in this suture from end to end and possessing a bulimine aperture. 
The typical species of Hhrenbergina are longer than Cassidulina and 
the margins are frequently serrate or spinous. 
Living representatives of the genus belong to southern oceans, and 
the bathymetric range is from several to over 2,000 fathoms. This 
species is well known from the Miocene. We find it rather abundant 
at several stations—H. 4430, H. 4476 (common), H. 4567, H. 4694, 
and H. 4696. —
