Punctum smithi Morrison, 1935

Family: Punctidae
Common name: Lamellate Spot

Width: ≈1.2 mm
Height: ≈0.6 mm
Whorls: 4+

The tiny shell of Punctum smithi is similar to its congener species – a depressed heliciform shape with a thin lip and an open umbilicus. However, its whorls are slightly flattened, so they are oval in cross-section (Pilsbry, 1948). The shell is sculpted with ridges, and these are crossed by spiral lines that vary in depth, giving the texture a “beaded” appearance. The aperture contains a recessed basal tooth, as suggested by its name.

This species is a leaf litter denizen, usually found with P. minutissimum (Hubricht, 1985).

Its name has no synonyms.

Punctum smithi occurs in scattered colonies in the Southeast from Maryland to northern Georgia. It is widely reported in Virginia.
