Shell perforate, turbinately depressed, siibleiiticular, tliiri, horny, 

 fiilvoiis, ornaraeiited above with line, oblique, costiilate striation, 

 bearing elongate granules arranged iu close spiral lines, smoother 

 and more polished, but still decussately striated, below, the spiral 

 impressed lines disappearing near the umbilicus : spire low couoid, 

 sometimes with concave sides, apex acute, sometimes prominently

raised and papillar, suture impressed ; whorls 6, regularly in- 

 creasing, convex above, the last sharply keeled, not descending, 

 swollen below ; aperture oblique, roundly lunate, angulate at keel 

 of last whorl ; peristome thin, basal margin regularly curved, 

 columellar briefly retiexed above.

The measurements are from an adult shell in Col. Beddome's 

 Collection. Benson's original type measured 29 mm. iu major 

 diameter, but was not adnlt. This shell, now in the Cambridge 

 Museum, had the keel white with the colour deeper on each side, 

 a coloration found in a few specimens only. 



E. jiraiemineas from S.W. Ceylon is a well-marked form with 

 the apex prominent and papillar, and the sides of the spire con- 

 sequently concave. The sculpture is a little weaker, especially 

 beneath the last wliorl. Other Ceylon specimens in my own and 

 my brother's collection connect the two forms. The type of 

 E. prceemhiens measured : major diam. 2;S|, axis 15 ram. 



[In a specimen from Watawala {0. CoUett) there is a minute 

 right shell-lobe but no left shell-lobe. The right dorsal lobe is 

 moderately large, the left in two distinct parts, the posterior long 

 and narrow (tig. 30 D, p. 52). The jaw has a central projection 

 on a strongly concave edge (fig. 30 D). The teeth of the radula 

 (fig. 30 D) are arranged : 54 . 1 . 21 . 1 . 21 . 1 . 54, or 76 . 1 . 76. 

 The mucous pore is large, extending to the sole of the foot, which 

 is undivided (fig. 30 D).]
