Furmations and Localities. — Upper Eocene (Barton Ecds) : Barton, 

 Hants (type); Alum Bay (No. 29 bed), I. of Wight. Middle 

 Eocene (Bracklcsham Beds) : Bracklesham Bay, Sussex ; Brook and 

 Bramshaw, in the New Forest.

 Museum, 1891, p. 262 {non Morlet). 



Shell small, globose ; consisting of four whorls regularly and con- 

 centrically grooved, but having a smooth and mammillated summit; 

 whorls with slightly convex sides, the last one of prominent length 

 and very venti'icose ; suture sub-canaliculate ; aperture wide, con- 

 tracted above and emarginate in front ; columella callous, bearing 

 three lamelliform plications, two being very antei'ior and nearly 

 horizontal, the third posterior and shorter; labrum thick, dilated, 

 not extending to the suture, furnished with obscure dentations within 

 and outwardly having a smooth rounded rim ; the columella and 

 labrum unite at both extremities. Dimensions : alt. 2, diam. 1*5 mm. 



In comparing this shell with Morlet' s Ringicida Bezanconi, from 

 France, it is found to differ mainly in having a somewhat smaller 

 aperture, caused by the posterior end of the labrum being remote from 

 the suture ; a greater space also exists between the labrum and suture 

 in R. ringens, Lam., which is besides smaller and less conical ; R. minor, 

 Desh., is further removed from our species by reason of its more 

 produced spire, deeper anterior sinus, and less globose form. 



Formation. — Upper Eocene (Barton beds). 



Localities. — Barton and High Cliif (type), Hants. 



EuLiMA MACROSTOMA, n.sp. PI. XXII, Figs. 7, 8. 

 Eulima macrostoma, Charlesworth MS., Morris, Cat. British Fossils, 

 1854, ed. 2, p. 247; li. B. Xewton, Syst. List Edwards 

 Coll. British Museum, 1891, p. 183. 



Shell small, composed of seven whorls ; apex acute ; whorls with 

 rather depressed sides, the last very long and centrally ventricose ; 

 suture distinct, slightly oblique ; aperture narrow, elongate, and 

 attenuated in front ; labrum arched, curved at the suture, margin 

 thin ; columella long, reflected, and oblique ; surface polished, por- 

 cellanous, smooth, with frequently obscure cicatrices on one side of 

 the spire. Dimensions: alt. 3, diam. 1mm. 



In comparing this species with F. concinna, Desh., from the Paris 

 Basin, M. Cossmann ^ remarks that it is distinguishable by being more 

 ventricose and more prominently arched at the labrum. It can also 

 be recognized from all other forms by the large size of the body-whorl, 

 which measures rather more than half the entire length of axis, by its 

 long aperture, and by tlie deeply curved sinuation at the suture. The
