LlNBSLEYA WOLLASTONIANA, Chitty. 



Hab. ? Hanover. 



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

 ture, about 31 veiy 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 mo- 

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

 stricted behind labrum, and then slightly 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, slightly concave, plain and smooth, 

 except a few coarse granulations.

 3£, moderately rounded, with a light suture. Aperture, constricted 

 at a distance behind labrum, and widely expanded and cupping in- 

 wards at the labium, rather flattened above. Labrum, moderately 

 produced above, treble in the upper part, broadly but not deeply 

 scolloped, and pectinated by the 5 stronger cariuse, much thickened, 

 white and shining. Labium, thickened and much reflected to the 

 left at its edge, curved to the right below, widely detached from body-
