164. EOCENE MOLLUSCA. 
The French specimens are generally ornamented with numerous pale orange- 
coloured bands; but the English matrix has been less favorable for the preservation of 
the colouring matter, and specimens retaining traces of the original marking are very 
rare. 
The shells described in Mr. Dixon’s work as V. spinosa, and V’. spinosa, var. platy- 
spina, (p. 107, t. 7, f. 22,) do not belong to this species; nor, apparently, do those 
described by Galeotti from St. Josse-ten-Noode, St. Gilles, Foret, and Affighem in 
Brabant ; in them, the ribs are thick, round, and prominent ; and the whole surface 
presents a transverse sculpture. Philippi records a specimen of the present species 
from Westeregeln, in the Museum at Halle; but as Dr. Beyrich does not mention the 
species among the Volutes described by him from that locality, I have cited Philippi 
with a query.

V. testa ovato-oblongd, partim costatd, antice transversim sulcatd, postice levi; spiraé 
brevi, apice acuto; anfractibus sub-ventricosis, postice acute angulatis, und serie spinarum 
donatis, margine suturali sub-convexo: labro simplici, tenui ; labio parum expanso ; colu- 
mella biplicata. 
Shell oval-oblong, longitudinally ribbed, transversely furrowed in front, otherwise 
smooth, with a short pointed spire: whorls rather ventricose, acutely angulated at the 
shoulder. The ribs, which are not numerous, extend over about two thirds of the whorl, 
and terminate at the shoulder in a row of short erect spines. In young shells a second 
row of small pointed tubercles, corresponding with the spines, runs round the suture ; but 
they soon disappear, and generally are replaced by an irregular raised line. The margin 
of the whorls, between the shoulder and the suture is slightly convex. The aperture is 
of a lengthened-oval shape, rather effuse and widely but not very deeply notched in front ; 
the outer lip thin and smooth; the inner lip but slightly spread out; the columella 
rounded, nearly straight, and furnished with two unequal folds. The surface of the 
shell is ornamented with transverse, narrow, orange-coloured bands, resembling those
