NOTES ON RETICULARIAN RHIZOPODA, 59 
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 superior end. Length, ; inch (0°56 mm.) ; breadth 
near the middle of the test only slightly less. 
B. amygdaleformis, nov.—Test oval, compressed, almond- 
shaped; ends obtuse or rounded, periphery rounded. 
Segments few; septation obscured by a surface orna- 
mentation of stout, branching, longitudinal cost. 
Terminal chamber nearly smooth and conspicuously 
perforated ; aperture central, of long oval form, 
slightly constricted at the middle. Length, = inch 
(0°72 mm.). 
B. subangularis, nov.—Test oblong, tapering, stoutly built, 
more or less angular, somewhat concave or excavated on 
both sides; inferior extremity obtusely pointed. The 
angular contour is determined by the prominence of 
superficial coste, the principal of which, six in number, 
are placed, one down each lateral margin and two down 
each face of the test. Aperture comma-shaped. Length, 
=; inch (0°45 mm.). 
Cass1DULiINA, d’Orbigny. 
Cassidulina Parkeriana, nov.—Test crosier-shaped ; spiral 
portion short, somewhat compressed, composed of few 
segments arranged as in C. crassa; linear portion 
straight or arcuate, cylindrical, biserial, the ends of the 
segments overlapping alternately ; chambers short, 
ventricose. Aperture comma-shaped, situated on one 
of the lateral faces of the terminal segment, near its 
apex. Length, ,, inch (0°57 mm.). 
The Rev. A. M. Norman has a crosier-shaped species 
in some respects similar to this, with the manuscript 
name Cassidulina Bradyi, but the segments are long 
and oblique, and the whole shell is compressed and 
Vaginulina-like. 
C. Jonesiana, nov.—Test oblong or ovate; external aspect of 
the superior surface like that of a very thick Rotalian, 
with slightly inflated chambers and rounded margin. On 
the inferior face the umbilical ends of the chambers fall 
short of the centre, leaving a deep cavity or depression, 
from which the aperture proceeds, taking the form of a 
curved, nearly erect slit, on the inferior face of the large 
terminal chamber. Diameter, =; inch (0°7 mm.).
