Monilea belcheri, common name Belcher's top shell, is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.[2][3][4]
Description
The size of the shell varies between 12 mm and 17 mm. The umbilicate, thin shell has a depressed-conoidal shape. It is sharply transversely lirate with narrow, elevated, sharp lirae, of which three are stronger, alternating with two or three smaller ones; about 12 similar ones are on the base; all of them are crossed and made subgranose by closely crowded growth lines. Its surface is white, painted with scattered red dots and a few larger red spots. The apex is white or rose-red.The strongly convex whorls are separated by a subcanaliculate suture, the last rounded. The umbilicus is moderate in size and surrounded by a peculiarly reddish-brown colored callus. The aperture is subrhomboidal. The columella is nearly perpendicular and incised at its base. [5]
Distribution
This marine species occurs on sandy beaches and in the subtidal zone off Thailand and in the Western Pacific (Fiji, Tonga, New Caledonia) and off Japan and Queensland, Australia.
