PULMONATA. 87 



one ; M. Deshayes, in fact, (' Descr. des Coq. Foss.,' &c. vol. ii, p. 92,) has suggested 

 that it may be merely a variety of L. longiscata. The Hordwell shells, like the 

 French, are shorter, and the whorls are more convex ; but they present the charac- 

 teristic fold of the present species, of which I consider them to be, therefore, only 

 a variety. 



Size. — Axis, 2 inches ; diameter, 8-10ths of an inch. 



Localities. — Hordwell ; Headon Hill ; Sconce. French ; Belleville ; Saint-Ouen ; 

 Fontainebleau ; Rochechouart ; Veaurs, and Vergnols, near Aurillac ; Dax. 



No. 33. Limislea sulcata. F. E. Edwards. Tab. XIV, fig. 4 a — b. 



L. testa ovatd ; anfractibus quinque vel sex, convexiusculis, substriatis ; spird mediocri, 

 acuta ; aperturd ovatd, spirant in longitudinem super anti ; margine externo parum obliquo ; 

 plied columettari compressd, vix eminenti, profunde sulcata. 



An ovate shell, composed of five or six slightly convex whorls on which the 

 lines of growth are very conspicuous, imparting a sub-striated appearance to the 

 surface; the spire moderately elevated and pointed. The aperture is ovate, and 

 rather longer than the spire ; the outer lip but slightly oblique, and the columellar 

 fold compressed, not very prominent, and more deeply sulcated than in any other 

 species. 



In general appearance this species resembles L. arenularia ; but it may be distin- 

 guished by the flat and deeply sulcated fold. 



Size. — Axis, rather more than 1 inch ; diameter ^ an inch. 



Localities. — Hordwell ; Headon Hill. 



No. 34. Limn^ea gibbosula. F. E. Edwards. Tab. XIV, fig. 8 — c. 



L. testa ovatd, sub-turritd ; spird brevi, sub-acutd ; anfractibus sex, gibbosidis, ultimo 

 magno, suturis profundis : aperturd acuto-semi-ovali, ampld, basi ejfusd, besseni totius testa 

 in longitudinem superanti ; labro rejlexo ; plied columellari parvd, parum tortuosd, sub- 

 compressd, obscure sulcata. 



An ovate sub-turreted shell, with a moderately elevated and rather obtuse spire ; 

 volutions six, somewhat gibbous, separated by a deep suture, and, in some specimens, 

 flattened round the upper margin ; the last volution is proportionally large. The 

 aperture is semi-oval, dilated in front, acute behind, and exceeds in length two thirds 

 of the whole shell ; the inner lip is reflected ; the columellar fold small, somewhat 

 compressed, not much twisted, and obscurely sulcated. 



This species resembles L. sublata more than any other; but the shell is larger, 

 the spire not so much elevated, the volutions more equally gibbous, the aperture 

 much longer and more effuse at the base, the fold not so much twisted and the outer
