contact with the penultimate whorl throughout. The tube appears broken 

 at the end, and may have been even longer originally ; the anterior termi- 

 nation in the specimen is in a line with the oblique peristome of the shell. 

 Aperture diagonal, circular ; peristome double, inner lip sharp, not project- 

 ing much, curved backwards near the penultimate whorl ; outer peristome 

 expanded, and wavy above externally and below, straight and somewhat 

 narrower on the left margin. Operculum nearly flat externally, concave 

 within ; the outer margins of the whorls free and lamellar, except towards 

 the middle ; the circumference surrounded by several fine raised lines, the 

 edges of the outermost whorls. Major diameter 0'5 inch, minor 0'42, 

 axis 0'3, diameter of the mouth 0'23. 



This species differs from all others of the genus by its higher spire, 

 and by the combination of the mouth being free and the sutural tube being 

 directed forwards and attached to the last whorl. The solitary specimen 

 obtained was procured at a considerable elevation, 4000 or 5000 feet, ia 

 the hills between Travancore and Tinnevelly, not far from Cape Comoria.

Shell subperforate, subovately turreted, solid, rather coarsely and sub- 

 sinuately costulated, of a pale straw-colour. Spire turreted, with convex 

 sides, apex rather obtuse, sutures well impressed. Whorls 7^-, convex, the 

 last more closely wound than the penultimate, to which it is scarcely attach- 

 ed just behind the mouth ; the basal keel compressed, costulate, dilated iu 

 front ; the space inside the keel and around the umbilicus is of moderate 

 size and ribbed. Aperture nearly circular and subvertical, with the opening of 

 the basal canal on the left side of the base, and not quite in the same plane 

 as the aperture, but turned rather downwards. Peristome white, thickened, 

 expanded, and turned back, produced above to the right of the penultimate 

 whorl and below around the canal, narrow on the columellar margin, and
