This species is the commonest of all the Virguline group, and that which presents the 
nearest approach to the typical Bulimine structure. The test is proportionately longer 
than in most of the true Bulimina , the segments are fewer, and they exhibit a tendency, 
especially in the later stages, to a binary or Textularian, rather than a more complex 
mode of growth. 
Virgulina schreibersiana is found in nearly every part of the world. It is abundant 
in the North Atlantic, and is scarcely less frequent in the South Atlantic, the North and 
South Pacific, the Indian Ocean, the Red Sea, and the Mediterranean. It is also at 
home on the shores of Franz- Josef Land and in Smith Sound, as far as 79° -or 80° north 
latitude. Its distribution depends but little on the depth of the sea-bottom, but includes 
a range of from 10 to 3000 fathoms. 
As a fossil it is probably not found earlier than the middle of the Tertiary epoch ; 
but from the Miocene period to the present time it is of constant occurrence in marine 
formations. 
Virgulina pauciloculata, n. sp. (PI. LII. figs. 4, 5). 
Test elongate-oval or subcylindrical, somewhat compressed, tapering slightly; ends 
rounded ; aboral extremity mucronate. Segments few in number, long, erect, but little 
inflated, irregularly arranged. Aperture a curved loop, situated on the inner face of the 
final chamber. Length, ^th inch (0‘ 42 mm.). 
This is a minute species, sufficiently distinguished by its few, erect segments, and their 
irregular disposition. 
It has been found in four localities, all of them on the shores of Papua or the adjacent 
islands, namely: — Humboldt Bay, north coast of Papua, 37 fathoms; at Station 189, 
on the south coast of the same island, 28 fathoms; Torres Strait, 3 to 11 fathoms; and 
off the Ki Islands, 129 fathoms.
