36 MOLLUSCA FROM THE GREAT OOLITE. 
sharper folds on the columella. With JV. elegans (Thurm.) it may perhaps be identical, in 
which case that name must be adopted for it: until this is decided we must call our shell 
VV. punctata, as it is clearly the species so designated by Voltz. 
Sutural angle, about 92° 
Basal angle, about 120° 
Length, from 1 to 2 inches. 
Locality. Found in the shelly beds near Minchinhampton, and more frequently in the 
quarries to the north of the vale of Chalford.

N. Testa turritd, longissimd; anfractibus superioribus concavis, transverse striatis, 
inferioribus subplanis, aliis ad suturas tumescentibus, aliis vie prominulis ; columella solida, 
triplicatd, labro dextro uniplicato. (Deslongchamps, 1. c.) 
Shell very long and taper, but differmg in the spiral angle in different specimens from 
8° to 12°; the upper whorls are concave, with a strong projection at the suture, variously 
ornamented with from 5 to 10 transverse ribs of unequal fineness, one or two of which (in 
very well-preserved specimens) are seen to be composed of small knobs ; the lower whorls 
become gradually flatter and smoother, and finally lose all traces of ribbing: columella 
solid. Four internal folds, viz.: one strong, thick fold on the outer lip, rather below the 
middle of the whorl; two on the columella, of which the lower sharp and well-defined is 
situated below that on the outer lip, and the upper faint and sometimes hardly visible, is 
placed opposite to the upper edge of the outer fold; and one sharp and long fold on the 
top of the whorl, close to the columella. 
Nerinea cylindrica of Deslongchamps appears to be a tapering variety of the same shell, 
in which the upper fold on the columella is ill-developed, or perhaps imperfectly seen. 
This species is also closely allied to WV. fibula, N. Goodhall (not Sowerby’s species), and 
N. clavus of Deslongchamps, all of which are probably one species: it differs from them in 
the greater concavity of the whorls, the transverse ribbing, and the presence of the upper 
small fold on the columella. It has probably been confounded with JV. fasczata of Romer— 
a species which sadly wants revision. 
Sutural angle, about 105°. 
Basal angle, about 120°. 
Length, up to 5 inches, but rarely exceeding 3 inches. 
Locality. Vt is tolerably abundant in the shelly beds near Minchinhampton ; but owing 
to its great fragility, large specimens can rarely be procured entire.
