and there is uo trace of labiation inside the aperture. The anatomy 

 diii'ers considerably. There is no dart-sac ; the kale-sac of the 

 penis is much longer and the spermatheca short and club-shaped, 

 with the terminal poi'tion ovate. The teeth on the radula are 

 arranged thus : 38 . 2 . 12 . 1 . 12 . 2 . 38 (52 . 1 . 52) and rather 

 peculiar in shape.

Shell depressedly convex, shining, thin, horny-ochraceous ; 

 spire broadly conical, obtuse ; whorls 5, almost not convex, 

 smooth, separated by a shallow suture, rapidly increasing, the 

 last Aery large, much ronnded ; umbilicus small ; aperture semi- 

 lunar, scarcely oblique, simple, not thickened nor sinuate, briefly 

 reflected at the coiumellar margin and deflected at the umbilicus, 

 the margins united by a very thin callus.

 broad (Ancey in Latin).

" Easily distinguished from E. hiJineatus, Godwin-Austen, of 

 Dafla Hills, by its larger size, more solid shell, its yellow-ochre 

 colour, and its less globose form." 



I am unacquainted with this species.
