Fossarinae apparently belong in Planaxidae, the resemblance to
Vanikoridae being perhaps superficial. Can't remember who moved
Fossarinae there.

This shell doesn't appear to be a fossarine. Fossarines lack terminal
varices and collabral riblets. Just waiting fom my old G3 to reboot
ino an older OS so that I can sharpen your images...

OK, with an unsharp mask & increased contrast things are clearer. I
find it often helps to reduce brightness and then increase contrast.

What I'd say you have is a species of Crosseola (Turbinidae:
Skeneinae). The cancellate ornament & anteriolabral notch terminating
the circumumbilical cord are characteristic. It is very likely
undescribed.
