Quantula sp.

Material examined.

Specimens from limestone outcrop at Tam Nang Rod Cave, Na-dan village, Yommalath District, Khammouan Province, Laos (Fig. 32E).

Remarks.

These specimens differ from Quantula weinkauffiana in having a smaller shell, upper shell surface with prominent nodules arranged on transverse ridges, and these ridges diminish below the periphery. In contrast, Q. weinkauffiana has a larger shell, an upper shell surface with smooth transverse ridges that terminate at the peripheral keel, and a smooth surface below the periphery.
