Genus Spiraculum Pearson, 1833

1833. Spiraculum (part.) Pearson, J. Asiat. Soc. Bengal., 2: 590.

1902. Pearsonia Kobelt, Das Tierreich Mollusca: Cyclophoridae : 171.

Type species. Spiraculum hispidum Pearson, 1833 .

Description: Shell depressed, subdiscoidal, covered with a thick periostracum, sometimes hairy or zigzag stripe; spire flats or somewhat elevated; aperture circular or diagonal, the edges of the peristome curved and projecting; last whorl with a short reverted sutural tube, open at both ends; shell widely umbilicated; Operculum with multi-spiral.

Remarks: Pearson (1833) nominated the generic name Spiraculum and designated Spiraculum hispidum as a type species. However, Kobelt (1902: 171) ambiguously proposed a new replacement name for it as Pearsonia . Much later, the detailed discrepancy has been described and resurrected Spiraculum as a valid genus by Inkhavilay et al. (2019).
