Denticulated Siphon Shell, Siphonaria denticulata
It has a prominent siphonal groove on the undersurface.
The shell is flatter but stronger ribbed than the Corded Siphon Shell, Siphonaria funiculata.
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.
The Denticulated Siphon Shell commonly occurs along from central Queensland to Wilson's Promontory, Victoria. Some references state a tropical and eastern distribution.
Ellsiphon marza, Iredale, 1940, is a synonym.
