Easter Island bubble-shell

May 17, 2002
From: Bret Raines

Hello Bill,
I would welcome some help in identifying this cephalaspidean from Easter Island.

Dredged at 30-50m in fine sand, off the western coastline near Tahai, Easter Island. Shell length: 2mm

Sincerely,
Bret Raines

Dear Bret,
Unfortunately this shell shape seems to have evolved a number of times amongst the cephalaspideans. Apart from suggesting it may be a Cylichna or Retusa, I'm afraid we would need some anatomical information to decide what family it belongs to.
Best wishes,
Bill Rudman
