spire only, just below the suture, and on the front half of the body whorl ; the whorls, 
although described as “almost flat,” appear from the figure to be roundedly convex, 
and to be contracted towards the base, the columella is without the ridge, the presence 
of which evidences a deep notch, and the columellar folds appear to be nearly equal in 
size. In all other respects the two species agree. As to the transverse striation, that 
character becomes feeble on the last whorl of some of the English shells, and the 
absence of it in the only specimen of V’. decora, possessed by Dr. Beyrich, and from 
which his description is taken, may be due to an imperfect preservation of the surface ; 
the only difference, in fact, of specific value, is the character of the notch. Dr. Beyrich 
himself expresses great doubt whether the VY. magorum of Sowerby is the same as his 
shell, and, without an actual comparison of the shells, I cannot venture to affirm their 
identity. If they should prove to belong to the same species, the name V. decora 
imposed by Dr. Beyrich will supersede the one I have given. 
Individuals of the present species occur, although very rarely, at Bracklesham Bay, 
and usually retain traces of their ornamental colouring, consisting of numerous dark 
brown transverse bands, which I have not found in specimens from other localities.

Shell oval-oblong, turreted, longitudinally ribbed, otherwise smooth ; spire mode- 
rately elevated, and terminating in a small, conical pullus: whorls six or seven, slightly 
convex; ribs rather numerous, thick, round, extending in front almost to the base, and 
prolonged backwards to the very edge of the whorl, where they terminate abruptly, 
forming, with their truncated extremities, a flattened ledge, which gives a turreted 
aspect to the spire. The only specimen I possess consists of the spire, the front part 
of the shell being broken away; but in the French shells the whorls are traversed 
at the base by several undulating striz; the aperture is of a lengthened oval shape, 
deeply notched in front; the outer lip is much thickened, and smooth within; the 
inner lip is narrow, and the columella presents three moderately oblique folds in front,
