Form, globose-conic. Colour, pale horn. Sculpture, lines of 

 growth visible : 4 strong spiral carinse and 1 fine ; 6th strong, 

 7th fine ; 8th strong, and 9th and 10th fine; 11th strong, 12th to 

 15th fine; 16th strong, l/th to 19th fine; 20th strong, 21st to

 to 36th fine ; on upper whorls, 5 strong, with fine ones on the inter- 

 mediate spaces. Spire, much and concavely elevated. Whorls, 

 3f, convex, with a well-impressed suture. Aperture, more than a 

 semicircle, more angular above than L. Leana, very slightly con- 

 stricted and dilated again slightly, more so below ; less campanulate 

 than L. Leana ; aperture lai-ger and wider above than L. Leana. La- 

 brum, not produced above, continuous all round with labium, sharply 

 and slightly reflected at rather more than a right angle, with a ridge 

 on the inner side, very slightly pectinated by about ten points of the 

 strong spiral carinse, not thickened as in L. Leana ; rather double

Form, globose-conic. Colour, light red-brown. Sculpture, an

 elevated, with convex outlines. Apex, acute. Whorls, 4^, quite 

 round, with a very deep suture. Aperture, subelliptical, rather flat- 

 tened above and broad-spreading, narrowed below and rather straight- 

 ened on the labial side, not in the least degree angular above or below; 

 labrum and labium continuous, much reflected. Labrum, excessively 

 double, especially above, where the outer stands clear out from the
