buccinidae

[paul monfils]

1.  Probably a worn and faded Engina bonasia I think.

2.  The one on the left resembles a few species - Engina alveolata, Engina fusiformis, and interestingly, a member of a different family, Morula parva.  The color tends to match the latter two species, but the sculpture matches Engina alveolata very well, so that's my choice.  The yellow areas are more red in fresh specimens, but I think this one is faded.
The shell on the right appears to be a Cantharus or Pollia.  The coloration suggests Cantharus (Pollia) wagneri but it could also be a color form of Cantharus fumosus.

3.  Engina bonasia

4.  Beautiful shell, but I can't place it.  I think it may be Muricidae though rather than Buccinidae.

5.  These look like Anachis, but I can't place the species.
