one large fold on the outer wall, and a smaller one on the 
posterior wall, height about 2 inches, diameter of the last 
whorl 4 lines, spiral angle 13°. 
This shell, in its internal structure, resembles that of N. 
oolitica, but the whorls are more tumid, and not so high, in 
comparison with the diameter, as in that shell. In the better 
preserved examples the upper end of the two last whorls are 
angulated, as shown in fig. 5b. 
Locality. Swift’s Hill, near Stroud, in the marly limestone 
bed. 
Nerina pisouitica, Witc.,n. sp. PI. I, fig. 6, 6a, 6D, 
Shell elongated, cylindrical, whorls smooth, regular, their 
height a little less than the diameter, suture faintly shown, 
aperture short, outer lip with an obtuse angle near the middle, 
columella with three folds, the posterior fold bifurcated, the 
middle fold simple, the anterior fold expanded and angulated, 
having three angles; the outer wall has a simple posterior fold, 
and a large fold near the middle, extending over one-third of 
the height of the volution; there is an obtuse fold on the 
posterior wall, and a smaller obtuse fold at the base of the 
figure. 
The internal structure of this species differs from that of 
N. Oppelensis, Lyc., in the anterior fold on the outer wall, 
which in the latter is represented by two folds, but the figure 
externally is different, the whorls not being concave, as in 
Lycrrt’s species. 
Locality—The pisolitic beds near Stroud, and at Longfords, 
near Nailsworth ; abundant. 
NeERIN@zA aTTENvaTA, Witc.,n. sp. Pl. I, fig. 7, 8, 8a., 
and Pl. II, fig. 6. 
Shell attenuated, whorls numerous, about 15, their height 
slightly less than the diameter, somewhat depressed at the 
middle, but more tumid at the suture; in the earlier stages at 
the junction of the whorls there are prominent ridges, which
