Chlorodiloma millelineata is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.[1] [2]
The height of the shell attains 19 mm, its diameter 21 mm. The thick shell has a very deep umbilicus, nearly reaching to the apex. It is a little shining, yellowish, with elongated flexuous unequal brownish-green spots and dots of the same color. The acute spire is little elevated. The 6 whorls are obliquely striate. The body whorl is very large and contains numerous irregular spiral ridges, stronger and numbering 6 on the base, with obliquely striate interstices. The oblique aperture is rounded, nacreous with greenish reflections and showing the folds inside.[3]
This marine species is endemic to Australia and occurs in the Torres Straits and off Queensland.
