Atys?, Haminoea? from Red Sea

From: Erwin Koehler

Bill,
This photo was made by W. Seifarth at Safaga Housereef, Red Sea, date unknown, size about 1,5 cm. Wolfgang asked me to post it at the Red-Sea section of my website (will be done soon, after identifying). He identified it as Hydatina sp. - do you know more?

Dear Erwin,
I don't think this is a Hydatina or even a close relative (Bullina, Pupa etc). From the shape of the animal I am pretty sure it is either a Haminoea or Atys. From memory I think Atys naucum has dark growth lines across the shell in the juvenile shell. Perhaps someone can help?
