Shell cylindrical, of a brown colour, and extremely glossy ; 

 body somewhat shorter than the spire ; which consists of five 

 nearly flat volutions, decreasing but little in diameter, except 

 the two upper ones, which are a little less, somewhat paler, and 

 terminating in a blunted apex ; volutions divided by a well 

 marked suture, and covered with remote, regular, longitudinal 

 striae, which are invisible without the aid of a strong lens; aper- 

 ture subovate ; pillar lip slightly reflected on the columella, with 

 a small subumbilicus behind; outer lip thin, and even. Length 

 about the tenth of an inch ; diameter nearly a sixth. 



Found in damp situations amongst moss and jungermanniaj.

Acme minuta, Brown, Illust. Conch., p. 35, pi. 14, f. 26; lb., 

 First Ed., pi. 41, f. 26. 



Shell cylindrical, smooth, shining, and of a greenish-brown 

 colour ; spire consisting of four slightly raised volutions, sepa- 

 rated by a well marked suture, and terminating in an obtuse 

 apex ; aperture subovate ; piHar lip slightly reflected on the 

 columella ; outer lip thin, and even on the edges. Length 

 about the tenth of an inch ; diameter not a sixth. 



I found this minute species at Douglas Castle, Lanarkshire, 

 amongst jungermanniaj, in the low meadow land below the old 

 tower. 



This species may be distinguished from the A. fusca by 

 being longer in proportion to its breadth, in the volutions being 

 more inflated, and in being entirely destitute of spiral striae.
