The Denticulated Siphon Shell has a very limpet-like shape, with prominent white radiating ribs and a strong, scalloped margin.

It has a prominent siphonal groove on the undersurface.

This shell's base colour is grey to buff, with prominent white ribs and light brown markings between. Inside the shell is dark brown with a white edge.

Distribution:

The Denticulated Siphon Shell commonly occurs along from central Queensland to Wilson's Promontory, Victoria. Some references state a tropical and eastern distribution.

Habitat:

The Denticulated Siphon Shell occurs over the whole tidal region on rock platforms and lives with the Variegated Limpet, Cellana variegata and the Corded Siphon Shell, Siphonaria funiculata.
