Shell rimate, turreted, white (fresher specimens are probably yellowish 

 white and polished), all the whorls ornamented with close vertical ribs. 

 Spire almost regularly attenuate, apex blunt, suture rather deep. Whorls 

 6^, convex, swollen, and projecting beneath the suture, increasing in size 

 by degrees, the last not ascending near the mouth. Aperture nearly round, 

 except above, with one strongly developed parietal lamella, commencing 

 in the front and re-entering deej^ly, a little twisted within, and so large 

 as almost to cut off the upper left or posterior portion of the aperture ; 

 another smaller, deep-seated columellar fold is scarcely discernible from the 

 mouth ; no palatal teeth. Peristome continuous, attached for a considera- 

 ble distance to the last whorl, white, thickened, broadly expanded, granulate 

 inside ; the columellar margin with an angular incision, the basal margin 

 broader than the others, right margin curved back near the angle, and 

 having a blunt projecting tooth-like process inside, opposite the parietal 

 fold. Length 0"15, diameter O'OB, length of aperture within 0.025 inch. 



The above description is taken from the only specimen I have ever 

 seen, which is in the British Museum. The shell is remarkable for its 

 peculiarly shaped whorls, each of which is suddenly swollen below the 

 suture, so as to give almost a step-like appearance to the spire. The round- 

 ed mouth, too, with the broadly expanded peristome is quite different from 

 that of any other Indian form of the genus. Perhajjs the Khasi-Hill 

 Ennea vara is as closely connected as any of the South-Indian forms, 

 though there is but little i-esemblance between it and the present species, 

 except such as is due to both being strongly ribbed, and to the manner in 

 which the posterior or upper right-hand corner of the mouth is almost 

 isolated by the strong parietal lamella and a projection from the inner 

 margin of the peristome.
