Unknown shell - help wanted

[jandelsing]

Hello,
This shell is puzzling me for some time. It is from an old collection, without finding data. I don't now in what family it belongs, looked in very much books and on very much sites with pictures, but without result.
Remarkabel:
- No columellar plicae ( wich sorts out many possibilities, f.i. vexillum)
- No labial teeth
- Protoconch domeshaped and involved (possibly heterostrofe)
- Sculpture as in some lyria-shells (volutidae)
Is this a buccinid, a fasciolariid, a volutid, or possibly a pyramidellid? I don't know.
