Stone.” Insome parts the test exhibits the tubulation of the 
calcareous wall characteristic of the group. 
Three specimens of Nodosaria radicula were seen in the 
limestone (bed no. 9) of Wedmore.

The above species has been noticed from various strata of 
Secondary age. ‘There is not much doubt that the Wedmore 
specimen is referable to the same type, although it is not 
safe to speak with certainty, since we have only the vertical 
section ot the test in the thin rock-slice. 
This specimen was found in the porous-textured rock, and 
the test has been apparently dissolved away in places, leaving 
a cavity of the exact outline of the fossil; and into this space 
numerous minute scalenohedra of calcite project from each 
wall. Other parts of the test show tubulation of the calca- 
reous shell.

TRUNCATULINA, d’Orbigny, 1826. 
26. Truncatulina stelligera, sp. n. 
(Pl. XII. figs. 14 a, d.) 
Superior face flat, with three whorls, the initial chamber 
spherical and prominent; inferior face strongly convex. 
Surface of test distinctly punctate. The convex face has 
raised lines of shell-substance radiating from the umbilicus ; 
the rays are thickest in the middle and taper towards the 
ends. Peripheral edge rounded. Diameter of test 5'5 inch 
(05 millim.), height 45 inch (0°21 millim.). 
The genus Zruncatulina is represented in strata as old as 
thé Carboniferous Limestone. ‘The above species differs from 
any form previously described chiefly in the sutural orna- 
mentation of the inferior face, and which resembles that seen
