Slu^ll fusiform, with pyramidal spire and short canal, stroni^-, dark red-brown, with a 

 yellowish zone on last whorl, quite covered by the suture in upj)er whorls and with whitish apex. 

 Whorls 9^2 ; nucleus consisting of 2 convex, light brown whorls, of which the upper one is 

 smooth and shining, the second has a prominent keel ; of the post-nuclear whorls, nearly 2 are 

 whitish, the whorls are convex, separated by a deep, waved suture, ascending towards the 

 aperture. Sculpture consisting of rounded ribs, 1 1 in number on last whorl, that preceding the 

 peristome very strong, and spiral lirae on the whole shell, 10 in number on penultimate whorl, 

 about 30 on last whorl and canal, of which 5 below the suture more crowded and fainter, 5 

 on the median part of ribs (6 on last whorl) are prominent and eventually a few intermediate 

 very faint ones; moreover faint growth-lines are visible and the whole shell except the nucleus 

 is covered with close-set, flattened granules. Aperture oblong, with a deep, narrow sinus, slightly 

 wider and rounded at its top, narrowed by a thick, incurved, enamellous, white rim on the 

 body-wall; peristome strong, serrated by small denticles, about 9 in number and intermediate 

 ones, only visible on the internal side and a second row of about 9 whitish tubercles, a little 

 more in the interior ; columellar margin lighter coloured than shell, nearly straight, with 7 trans- 

 verse folds. Interior of aperture smooth, light violet. Canal straight, narrow at its proximal end, 

 wider below.

Still allied to L. sptirca by its characters of aperture, especially by the sinus and by 

 the arrangement of its spirals, but quite peculiar by its granular sculpture.

Shell ovately fusiform, with rather short spire and short canal, strong, whitish, light 

 reddish-brown between the ribs, especially below the suture and a faint band of the same colour 

 below the periphery of last whorl. Whorls 9, of which 3 form a brownish nucleus, with convex 

 whorls, the two lower ones are keeled. Post-nuclear whorls short, convex, with a deep, waved 

 suture •, sculpture consisting of rounded axial ribs, 11 or 12 in number on last whorl, crossed 

 by more or less thick spirals, 7 narrow ones below suture, followed by six coarser ones on 

 penultimate whorl, about 28 on last one, besides a few intermediate lirae; moreover the shell 

 is covered with excessively fine spiral lines, which, under the microscope, prove to be composed 

 of rows of granules, much finer than in the preceding species. Aperture oval, with a rather 

 narrow, deep sinus above and a short, open canal below; peristome strong, subserrated and 

 internally with a few denticles, being the ends of internal lirae; columellar margin concave above,
