Interchangeable taxa

This species is identified by its moderate size, rounded whorls and specific colour patterns. It usually has a white base, but this is a character sometimes seen in other species, particularly M. semiconvexa. It is close to M. semiconvexa but smaller, and many specimens are impossible to positively separate. It is larger than M. leucostoma and of similar shape, and again positive separation is not always possible.
Beechey, Seashells of New South Wales.


Endemic to Australia; Jervis Bay, NSW, around southern Australia to south-western WA. Also some records of doubtful identification from Sydney.
Habitat: Intertidal on rocky shores.
