suddenly disappear, and the suture line becomes grooved, 
aperture large, outer lip angulated, channel lengthened. The 
internal characters are indistinct, but there is an obtuse fold 
on the outer wall, and indications of one on the columella, and 
one on the posterior wall; height 3 inches, spiral angle 10°. 
Locality.—Longfords, in the Pisolite, and at Swift’s Hill, 
near Stroud, in the marly limestone bed. 
Neriwwza Srrovpiensis, Witc., n. sp. PI. I, fig. 9. 
Shell conico-cylindrical, semi-turrited, whorls numerous 
(about 25 in an entire specimen,) their height equal to three- 
fourths of the diameter, each whorl projecting slightly at the 
suture, and angulated, apex acute; internal character unknown; 
spiral angle 8°. 
This shell is highly crystalline, its internal structure cannot 
therefore be ascertained. It has some affinity with N. conica, 
(fig. 2) but is more slender and cylindrical. 
Locality.—Swift’s Hill, in the marly limestone bed. 
Nerinma consoBRina, Witce.,n. sp. Pl. I, fig. 10, 10a. 
Shell conico-cylindrical, apex acute, whorls numerous, their 
height about four-fifths of their diameter, thickened at the 
suture in the earlier stages, but become nearly plain as the 
shell enlarges, the suture being slightly open at the junction of 
the two last whorls, aperture short, columella solid, with three 
folds, outer wall with three folds, and one small fold in the 
posterior wall, and an obtuse fold at the base of the figure, as 
in N. Oppelensis, (fig. 3a) height 4 inches, spiral angle 9°. 
This species differs very little in its internal structure from 
N. Oppelensis, but it has a more conical figure, and the whorls 
are higher, in proportion to their diameter, than in that species. 
Locality.—Longfords, near Nailsworth, in the Pisolite. 
Nerinza attivotuta, Witc.,n.sp. Pl. I, fig. 11, 12. 
Shell cylindrical, whorls very numerous, smooth, regular, 
their diameter equai to four-fifths of their height, suture
