 two subequal columellars, and two parietals, the inner one 

 larger. Peristome a little expanded, pale, somewhat thick- 

 ened, sublabiate, the margins connected by a thin callus. 

 Outer margin a little projecting and slightly impressed in the 

 middle. Length 1% to 2i/g, diam. 1 mm. (Bttg.).
