ficient. All, however, are characterized by the great development of the 

 parietal callus.

Shell umbilicated, depressed, globosely ovate, rather indistinctly striat- 

 ed, shining, translucent, pale yellowish white. Spire very low, scarcely 

 exserted, apex blunt, suture impressed. Whorls 5, convex, the penultimate 

 rounded behind, and not projecting, when viewed from below, beyond the 

 lower whorl ; the last whorl much larger than the others, eccentric, convex 

 below, smooth and polished, compressed around the umbilicus, especially 

 near the mouth, and constricted by indentations, corresponding to the teeth 

 inside, just behind the lip. Aperture oblique, nearly semioval, and furnish- ' 

 ed with two plaits on the parietal side, that to the left (nearest to the 

 ■umbilicus) longer than the other and bent inside ; there are five teeth in 

 the peristome, one on the columellar margin near the umbilicus, a second 

 lai'ge and double nearer the base, one lamellar and transverse at the base, 

 two inside the riglit margin, the lower being larger than the other and 

 almost bliid inside. Peristome white, slightly expanded, scarcely sinuate 

 near the angle, margins joined by a callus bearing the two parietal plaits. 

 Major diameter 23, minor 0'2, height 0'13 inch. 



This is the only known sjiecies from Southern India, so far as I am 

 aware, in which, when the shell is viewed from below in the direction of the 

 axis, the penultimate whorl does not project at all beyond the body- whorl. 

 The transverse lamellar tooth at the base of the aperture is also peculiar.
