Concerning message #16718:
Hi Bill and everyone!
Good to see you're back. Now onto more pressing matters... While David Mullins, Richard Willan and I were diving near Bulwer Moreton Island, we were sieving the sand just off the shore in 4 metres of water. In the bits were found 7 new species to nudibranch.com.au including 2 species of Ringicula.
Here are photos of the shells. I have also found one shell at Pt. Cartwright off Mooloolaba Queensland.
Locality: Moreton Island, 4 m, Queensland, Australia, Pacific Ocean, 10 April 2009, Subtidal and Intertidal. Length: 2-4 mm. Photographer: Gary Cobb.

Shells of white or colourless bubble shells are often very difficult to identify as they have few shell characters we can use for species identification - and in some cases it is impossible to identify which family they belong to from shell alone. Adding to the confusion are the many names that exist - many from early exploring expeditions - which are based on shell descriptions with no information on the animal's anatomy.
At this stage all I can do is put your shells on a Ringicula misc Pacific page in the hope that it stirs someone's interest in revising this group.
