Mike Kendall's picture

interesting

Its not Calliostoma...that is top shaped and this specimen has a stepped appearance when looked at sideways on.

It isn't G.umbilicalis which is far flatter in profile.

Gibbula tumida might be a better ID but its diffucult to be sure

....a scale would really have been helpful

perhaps

What a difficult group this is proving, for me and others it seems.

Not helped much by this shell being so incomplete.
Mike is right - perhaps Gibbula tumida.
Needs to be 'in' Invertebrates.

Need other views

The problem is the lack of views of the aperture and umbilicus.
Have a look at http://www.conchsoc.org/spAccount/gibbula-umbilicalis and http://www.conchsoc.org/spAccount/gibbula-tumida
The decoration does not appear to be like G. tumida.
