littli 1 prominent; it is hyperstomial and opens into the peristomie. The median

Affinities. The aspect of this species is lamentable; without grace or elegance, 

 it can not compare with any of the elegant Vicksburgian species. 



It differs from J'ml>oin/l/> fcrntitmorplia Renss. 1847. in its smaller dimensions 

 (Zs=0.44 and not 0.60 mm.) and in its much smaller areolae.

The bibliography of this species is rather confused, and as we have not at hand 

 the data for a serious discussion, we can consider therefore only the published 

 figures. Even in these narrow limits its cosmopolitanism is quite manifest. 



Our American specimens are escharian, whereas the European specimens are in- 

 crusting. According to present ideas this character is not specific.

The apertura is semicircular with poster slightly concave: it is deprived of 

 cardelles and bears a pseudolyrula formed by the elevation of the peristomial wall. 

 The operculum bears a chitinous mural rim incomplete at the level of the convexity 

 of the upper border and little removed from the lateral borders.
