slightly depressed, aperture sub-ovate, terminating in a small 
channel, rather pointed, columella large, with an acute fold 
on the anterior part of the volution, outer wall with one large 
obtuse fold near the middle, there is also a prominent fold at 
the junction of the columella with the posterior wall. 
This species, in its internal structure, has an affinity with 
N. pseudo-cylindrica, D’Ors., but differs externally in the 
unusual height of the whorls, which will readily distinguish it 
from contemporaneous species; it is also more cylindrical than 
D’Orzieny’s species. 
Locality.x—The Pea Grit, near Stroud, and at Longfords, 
Nailsworth. 
Nerinza Propucta, Witc.,n. sp. Pl. I, fig. 13, 13a. 
Shell sub-cylindrical, elongated, whorls smooth, regular, 
their height and diameter equal, suture faintly shown, aperture 
lengthened, narrow, anterior channel produced, slightly curved 
downwards, columella with three folds, the anterior fold very 
broad at the base, angulated with three angles, the middle fold 
slightly pointed downwards, the posterior fold bifurcated; there 
are three folds on the outer wall, the anterior of which is 
angulated, having three angles, the middle fold curved, the 
posterior fold truncated; there is a small fold on the posterior 
wall. 
This species is one of the group distinguished by a compli- 
cated internal structure, of which N. Oppelensis, Lyc., is a good 
example. It differs principally from the allied species in the 
increased height of the whorls in comparison with their 
diameter, in the narrow lengthened aperture, and in its great 
length, which, judging from the fragments obtained, cannot 
be less than six inches, and may be longer. 
Locality.x—Longfords, near Nailsworth, in the Pisolite. 
Nerinza vELOXx, Witc.,n. sp. Pl. II, fig. 3, 3a. 
Shell sub-conical, apex acute, whorls low, their height equal 
to about two-thirds of the diameter, much thickened at the
