Teinostoma (Leucorhynchia) caledonicum Crosse, 1867 Leucorhynchia caledonica is a species of sea snail, a marine gastropod mollusk in the family Skeneidae.
The polished, shining, whitish shell has a subdiscoidal shape and is slightly convex above and below.
The spire contains 3 flattened whorls that are rapidly increasing.
The simple peristome is continuous and is thickened at the base and produced into a tongue-like callus past the umbilicus, leaving a perforation between it and the columellar wall.
[2] This marine species occurs in the Western Pacific Ocean, off the Philippines, Indo-Malaysia, New Caledonia and Queensland, Australia; in the Indian Ocean off Réunion.
