Shell cylindric, glossy, pellucid, smooth, corneous; spire 

 conic, the apex rather obtuse. Whorls 7 1 /-?, flat, parted by a 

 slightly impressed margined suture, the last whorl about one- 

 fourth the total length. Aperture slightly oblique, half 

 round; peristome unexpanded, simple; right margin a little 

 thickened in the middle; columellar margin appressed to the 

 simple columella, and bordered with a white thread-like 

 callus ; margins united by a weak parietal callus, which bears 

 a thread-like tubercle near the insertion of the outer lip. 

 Length 9, diam. 2, alt. of aperture 1.75 mm. (Bgt.}.

This species differs from A. cylindracea by its greater size, 

 slightly swollen form, the reddish color of fresh examples, 

 convex whorls, deeper suture, and the slightly wider, less ver- 

 tical aperture, etc. Benoit gives the dimensions as 8x3 mm. 

 My figures are from examples received from Benoit, 7.2 x 2.5 

 mm., with 6% whorls. The aperture is moderately oblique. 

 The outer lip is thin and straight in its upper third, below 

 which it is noticeably contracted, white, and thickened with- 

 in. It is continued up the columella in a raised ledge, whence 

 a white cord passes across the parietal wall, and is thickened 

 into a triangular tooth near the upper angle of the aperture. 

 Between this tooth and the insertion of the outer lip there is 

 a deep and very narrow sinus. The columella is nearly 

 straight, and is weakly truncate obliquely at the base.
