Hi
Im trying to identify this cephalaspidean, as for now I have named as Retusa sp. or Cylichna sp. But I'm not sure about it. Could someone in the branch comunity help me?

The animal was collected in Bahia Magdalena, In Baja California Sur, in depth of 1 meter (3 feet) on sandy bottom, the size of the animal is 3.2 mm.
Thanks,
Orso Angulo

Dear Orso,
I am afraid these little bubble-shells are very difficult to place in a genus or even a family unless you can look at their anatomy. I would guess that your species is possibly a species of Retusa or perhaps Acteocina. If you are adventurous, have a look and see if it has a radula or gizzard plates. If it has, and you can describe them for us, we could almost certainly suggest a genus for you.

If we are lucky, one of our Californian colleagues may recognise it.
Best wishes,
Bill Rudman
