174 EOCENE MOLLUSCA. 



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 V. 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.

V. testa ovato-oblongd, turritd, longitudinaliter costatd, cceterum lavi ; spird mediocri, 

 acuminata, apice acuto : anfractibus convexiusculis ; costis crassis, rotundatis : aperturd

 columella triplicatd et rugis transversalibus instructd. 



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 striae ; 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,
