Shell subcylindrical, perforate, opaque, yellowish white, finely and closely obliquely costulated throughout; spire ovate, apex very obtuse; whorls 8, very slightly convex, the last three of nearly the same diameter, very gradually increasing, the last whorl slightly ascending near the aperture; suture somewhat irregular and presenting a puckered appearance caused by the meeting of the costulse ; aperture sinuately semioval, glossy within; paries armed with a large curved lamella extending far within the aperture and forming a deep canal with the outer lip, the lamella somewhat overhanging the canal; a thick tooth is situated about the centre of the outer lip near the margin, and an expansion or plication is placed behind the columella far within the aperture; labrum thickened, expanded and reflexed ; a pit or depression behind the labrum corresponds with the tooth within. Length 11^ millims., diameter of the three equal whorls 5|, diameter of aperture 3|. Locality. Leydenburg, Transvaal. ENNEA INFANS, sp. nov. (Plate LVII. fig. 6.) Shell cylindrical, perforate, semitransparent, yellowish brown, glossy, obliquely lirate (lirae attenuating inferiorly), and faintly spirally striate between the liree ; apex obtuse ; whorls 7\, a little convex, very gradually increasing, the last narrower than the two preceding and ascending slightly near the aperture; suture well marked, denticulated by the extremities of the lirse ; aperture small, sinuately semioval; paries furnished with a large straight lamella adjoining and forming a canal with the outer lip ; labrum armed with a tooth situated a little below its centre ; a pit or depression behind the labrum corresponding with the tooth ; peristome thickened, expanded and reflexed, of a pure white.
