regulariter crescentes, sutura subprofunda juncti, lineis incrementi 
tenuibus aliisque spiralibus subobsoletis striati ; apex obtusus, 
rotundatus ; apertura parva, rotunde subquadrata, longit. totius 
3 adsequans ; perist. vix incrassatum, margine externo et interne 
brevissime expanso, columellari late dilatato, callo tenni labro 
juncto.

This little species exhibits a distinct epidermis and has no 
teeth in the aperture. A slight sinus is visible in the outer 
lip near the suture. 
Ennea lendix. (PI. VI. fig. 16.) 
Testa cylindracea, imperforata, alba, subpellucida, nitida ; spira ad 
apicem obtuse rotundata ; anfractus 8, vix convexiusculi, heves, 
6utura simplice sejuncti, lineis incrementi vix striatuli ; apertura 
rotunde subquadrata, longit. totius | paulo superans, denticulo 
minuto supra medium columelke, altero majore, lamelliformi,

Like E. subflavescens and E . subhyalina this species is 
cylindrical, smooth, and very glossy, but differs in having 
only two teeth in the aperture.

ultimus interne liris paucis longit udinalibus instructus, antice 
contractus, utrinque labrum scrobiculatus ; apertura parva,

The mouth of this minute species is much closed up by the 
three denticles, which converge towards the centre. One on 
the outer lip and one on the columella are thick and rounded, 
whilst the third is thin, lamellar, and joins the upper termina-

suture appears to be faintly denticulate. The short longitu- 
dinal liras on the last whorl do not extend upward as far as
