Good one!
It may well be that not all specimens of a given morumine species are
operculate. I have collected 2 such (nonharpid) species.
The first Voutomitra banksi I found had a minute (1.5mm in a 30mm
shell) operc, which looks ridiculous mounted in the aperture; the few
subsequent specimens had no operc... and I looked hard!
The one Exilia expeditionis I have found had none, but the specimen
of this exceedingly rare beast currently on offer by Femorale (hi
Marcus!) as "Leucosyrinx nsp" (if Marcus hasn't yet had the chance to
update the site) has a good-sized operc.
