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. 



Jhe 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 Afflighem 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, anti'ce transversim sulcata, postice Icevi; spird 

 brevi, apice acuto ; anfractibus sub-ventricosis, postice acute angulatis, una serie spinarum 

 donatis, margine suturali sub-convexo .• labro simplici, tenui ; labio parum expanso ; colu- 

 mella biplicatd. 



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
