 Lahruni, vrell, and in an elegant curve, produced above, treble above 

 and double below, as in Helix Riipis-fontis in my cabinet (N. B. since 

 first describing Ibis shell it bas unfortunately got broken), very 

 slightly thickened at its extreme edge, and vvhite. Labium, mode- 

 rately detached ^from body-whorl, vvide and much reflected, curving 

 slightly throughout, below the plane of labrum. Umhilicus, mode- 

 rately deep and broad. Labral lameliu, slightly produced. Oper-

Fortu, subdiscoidal. Colour, pale horn. Sculpture, 27 fine sharp 

 spirai carinse, the 6th, lOth, 16th, and 23rd being rather stronger ; 

 on the upper whorls, 6. Spire, much depressed, with slightly con- 

 vex outlines. JFhorls, S^rd, moderately rounded, vvith a moderate 

 suture. Aperture, slightly depressed above, expanded below, semi- 

 elliptic. Labrum, produced above in a curve, leaving the body-whorl 

 in a quasi angle of about 80°, double and widely so above, pectinated 

 by about 5 points, very slightly reflected, white. Labium, nearly 

 straight, very little curved to the right below, slightly detached from 

 the body-whorl, on a plane with the labrum above, lower below. 

 Umbilicus, moderately deep. Labral lamella, rather produced in its 

 centre. Operculum, ?

 Apex, obtusely prominent. TVhorls, 3^, very slightly rounded, with 

 a deep suture. Aperture, more than a semicircle, rather expanded 

 above, ^ ery slightly deflected and expanded below. Labrum, slightly 

 produced above at the Ist and 2nd strong carinse, broadly pectinated 

 and scolloped by all the strong carinse. Labium, vvell-detached from 

 the body-\vhorl, below the plane of the labrum above, slightly 

 rounded and nearly up to the plane of the labrum in the lower end. 

 Umbilicus, moderately deep. Labral lamella, very sharp and narrow. 

 Operculum, deeply concave in the centre and minutely granulated ; 

 two or three microscopic lamellae crossing vertically, the edge all 

 round thickened and deeply reflected outward, the upper edge having 

 five or six deep ifregular vertical folds.
