This looks me C. decapitata (or decpitatus?). However I have not study this group in detail, I have check the original descriptions by reeve:

http://www.biodiversitylibrary.org/item/35859#page/178/mode/1up

See 83 = truncatus and 85 = decapitatus.

But, there are, in addition, two names commonly placed in synonym with decapitata:

-"Pisania" englerti Hertlein, 1960 - I have not study yet:

- "Triton" cylindrica Pease, 1868 - this is the more cylindrical morph usually found in Pacific.

Thank you Dr. Koen Fraussen ·

Thank you Dr Dekker

Dmitry Telnov

I agree your specimens are closer to C. decapitata rather than to C. truncata. But any identifications made on base of the photographs cannot be 100% sure

Gianluigi Bini

Not easy just by photo, but C. decapitata 90%. See my attach.

Gianluigi

Dear Gianluigi Bini,

Thank you so much

Dear Dmitry Telnov,

your opinion is correct, but good photographs are easy to identify

regards

Bushra Majeed Issa

Dear Mr. Ravinesh

It is closer to Caducifer decapitatus
