b\i 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 inwards, more so 

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

 wards the umbilicus. Labrum and labium continuous above ; labium 

 on a plane with labrum below. Umbilicus, deep. Labral lamella, 

 sharply produced as it leaves the labrum, becoming narrow, and 

 abruptly lost in the umbilicus. Operculum, ?

Form, globose-conic. Colour, pale horn. Sculpture, 19 strong, 

 rather inequidistant spiral carinse ; on the upper whorls 6. Strise 

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

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

 semicircular, rather flattened above, slightly expanded in the lower 

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

 strongly pectinated by spiral carinae. 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 horizontal raised lamellae 

 converging towards the umbilicus, the margins of which are covered 

 with fine granulations giving the appearance of serration ; lower 

 third laps tightly over the labium, grooved horizontally, and then 

 finished by a linguiform, raised, folding projection.

Hab. ? Hanover. 



Form, globose-discoidal. Colour, white, semitransparent. Sculp- 

 ture, about 3 1 very fine inequidistant, irregular, spiral, raised carinse, 

 about 8 rather stronger than the rest ; on the upper whorls 8. 

 Spire, slightly raised, with convex outlines. Whorls, 3f, very 

 moderately rounded, with a light suture. Aperture, slightly con- 

 stricted behind labrum, and then shghtly expanded, semicircular. 

 Labrum, very little produced above, thickened and reflected and very 

 slightly pectinated by the stronger carinse. Labium, well detached 

 from the body-whorl, moderately curved below, on a plane with the 

 labrum. Umbilicus, moderately deep and wide. Labral lamella, 

 narrow and sharp. Operculum, shghtly concave, plain and smooth, 

 except a few coarse granulations.
