Wollastonaria leacockiana is a species of small land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae. [1]
Description
(Original description in Latin) The shell is top-shaped, flattened and perforated on the underside, and densely covered everywhere with blunt granules. It has a pale, slightly yellowish-brown color, which is marble-patterned here and there with irregular reddish-brown bands (especially underneath) and cloud-like blotches (especially above).
The spire is moderately elevated. The whorls are convex and double-keeled; on the body whorl—which is somewhat roof-shaped—the outer keel is extremely sharp and strongly projecting, while the inner keel is blunt, rounded, set back, and occasionally obsolete. The umbilicus is tiny and pinpoint-like. The aperture is suboval to rounded, with the lips continuous and joined together, and the peristome is simple, expanded, slightly recurved, thin, and raised.[2]
Distribution
This species occurs in Madeira.
