lobulated. Surface of the test ornamented with numerous delicate, often branching; or 
otherwise irregular, longitudinal ribs. Segments inflated ; aperture large, oblique, 
bordered by a thickened lip. Length, ^fch inch (0‘63 mm.). 
This pretty species is abundant on the Hyalonema-ground, south of Japan, 345 
fathoms. It occurs also in the South Pacific, at two points off Tahiti, 420 fathoms and 
620 fathoms respectively; and in the South Atlantic, off Pernambuco, 675 fathoms.

Test elongate, depressed, digitate ; distal end obliquely truncate or rounded, aboral 
extremity obtuse, peripheral edge lobulated. Segments inflated, their outer margins pro- 
jecting and subangular ; sutures thickened, and deeply sunk ; surface especially of the 
later chambers more or less granulated. Aperture a long oval slit contracted at the 
middle; nearly central. Length, 6 \yth inch (0'4 mm.). 
Bolivina lobata has been obtained from four localities, all of which are near the Island 
of Papua, — two of them off the Admiralty Islands, 16 to 25 fathoms; the others, 
Humboldt Bay, 37 fathoms, and Torres Strait, 155 fathoms. 
Bolivina lobata, var. strigosa. — A clear-shelled variety of this species, with somewhat 
exaggerated peculiarities, occurs off Raine Island, Torres Strait. This is figured in PI. 
CXIII. fig. 7, and may be distinguished as Bolivina lobata, v ar. strigosa. The specimens 
are of about the same length as those of the type, but much attenuated ; the chambers 
are subtriangular, the inferior angles acute and projecting, and directed either outwards or 
towards the initial end of the test. It is less distinctly Textulariform than Bolivina 
lobata, quite hyaline in texture, and free from superficial granulation. 
Bolivina schwageriana, H. B. Brady (PL LIII. figs. 24, 25). 
Bolivina schwageriana, Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi., N. S., p. 58. 
Test oblong, biconvex, broadest near the middle, tapering to a blunt point at the 
initial extremity ; margin carinate. Keel widest near the middle of the shell, absent at 
the initial end. Sutures limbate, the limbation taking the form of raised beads or 
irregular lines of shell-substance on both sides of the test, chiefly near the points of 
contact of the two opposing series of segments ; surface otherwise smooth. Aperture 
large, with an oblique projecting tooth near the anterior end. Length, ^th inch 
(0‘56 mm.) ; breadth near the middle of the test only slightly less.
