152 F. Stoliczka — Notes on terrestrial Mollusca. [No. 2, 



posteriorly pointed. Tentacles blackish, thin and snbulate in 

 young, considerably thicker in older specimens ; eyes rather large, 

 black, placed laterally and somewhat posteriorly on distinct bul- 

 gings at the base of the tentacles ; rostrum rather short, slightly 

 cleft in front, the buccal parts red, shining through ; mantle with 

 a small slit on each side corresponding to the incision in the 

 shell, the lower edges of the slits are slightly thickened and 

 rather distinct, the upper almost perfectly continuous with the 

 outer, slightly thickened, edge of the mantle. 



The horny, moderately thickened, operculum closes the aperture 

 perfectly ; it has a thin fringe at its edge all round and is 

 externally slightly impressed in the centre. The live shell is 

 covered with a thin layer of slippery glaze. Young shells are 

 regularly coiled, like a little conoid Helix, and quite transparent. 

 There is no difference in the coloration of the sexes.
