Nermnma Vourzu, Desl. Pl. V., fig. 3. 
This shell is believed to be a full grown example of N. Voltzii, 
_ but in consequence of its crystalline condition its internal struc- 
ture cannot be ascertained, it must therefore be judged only 
from its external appearance, but it differs only in size from 
some of the examples of that species from Minchinhampton. 
If this view be correct, it would seem that the shells figured 
by D’Oxsreny and Morris and Lyczrr were immature forms ; 
_ the specimen now figured is many times larger than either of 
those figured by the authors named. 
Locality—Tiltup’s End, near Nailsworth, in the Nerinea bed, 
between the White Limestone and Forest Marble. 
Nerin#a. sp. Pl. V., fig. 2, 2a. 
Shell elongated, conico-cylindrical, volutions nearly flat, 
their height one-fourth less than the diameter; suture sub- 
obsolete, aperture nearly quadrate, outer lip angulated, channel 
small, curved backward, height probably four inches. . 
The form of the aperture distinguishes this species from 
_N. intermedia, with which it is associated ; there are traces of 
~ ornamentation upon the surface, in the form of encircling lines. 
The internal character is unknown. Having found only one 
fragment of this shell, I defer naming it until further specimens 
have been obtained. 
Locality —Tiltup’s End, near Nailsworth, in the White 
Limestone (Great Oolite.) 
Nermvma ? pusia,n. sp. Pl. V., fig. 9, 9a. 
k 3 Shell small, acute, volutions (eight) ornamented with very 
faint encircling lines, the last volution equal to two-fifths of 
the entire length, aperture small, sub-quadrate, channel slightly 
curved. 
_ This shell may perhaps be only a young example of Nerinea; 
its crystalline condition prevents an examination of its internal 
structure. It may possibly be a Cerithiwm. 
Locality —Bussage, in the Great Oolite.
