well-elevated, vvith rather convex outlines. Whorla, 3frds, veiy 

 •well rounded, with a deep suture, lašt whorl very globose. Aperture, 

 slightly and somewhat abruptly expanded, more than a semicircle, 

 subelliptical, slightly depiessed above and expanded below. Labrum, 

 rounded into labium, more broadly below, very slightly produced 

 aboTe, double, white, smooth, not pectinated. Labium, scarcely 

 detached from body-whorl, on a plane with labrum. Utnbilicus, very 

 shallow, broad. Labral lameliu, scarcely produced. Operculum, 

 slightly concave, very finely granulated in the centre.

This shell is likę L. Albersiana, but differs in sculpture, number

Hab. New Hope, Westmoreland. 



Form, globose-conic. Colour, pale horn. Sculpture, 16 strong 

 spirai carinse, onli/ about the periphery one fine iotervening ; on the 

 upper whorls, 5. Spire, well-elevated, with straight outlines. Whorls, 

 5\, well-rounded, with a deep suture. Aperture, less than a semi- 

 circle, very slightly spreading, and very slightly deflected below. 

 Labrum, slightly separated from body-whorl, rather produced above, 

 in a broad notch, pectinated by about 15 of the strong carinse. La- 

 bium, well-detached from body-whorl, curved invvards, more so 

 below J thickened and reflected in the centre and its lower end to- 

 wards the umbilicus. Labrum and labium continuous above ; labium 

 on a plane vvith labrum below. Umbilicus, deep. Labral lameliu, 

 sharply produced as it leaves the labrum, becoming narrow and 

 abruptly lošt in the umbilicus. Operculum, ?

 rather ineąuidistant spirai carinee ; on the upper whorls 6. Striee 

 of growth visible. Spire, moderately elevated, with rather concave 

 outlines. TVhorls, 4^, well-rounded, with a deep suture. Aperture, 

 eemicircular, rather flattened above, slightly expanded in the lower 

 two-thirds. Labrum, rather produced above, not reflected, thin, 

 strongly pectinated by spirai carinee. Labium, rather detached from 

 body-whorl, gradually curved to the right below. Umbilicus, ra- 

 ther deep and broad, slightly hidden by the labral lamella, which 

 is but little produced. Operculum, concave, finely granulated, with, 

 on the labral side extending half across, 5 horizontai raised lamellse 

 converging towards the umbilicus, the margins of which are covered 

 vvith fine granulations giving the appearatice of serration ; lower
