Hi everybody,
This is some pictures of three shells from the new caledonian lagoon (west pacific).
I am not sure about their name :
- Primovula sp.

- Phenacovolva... maybe philippinarum

- Prosimnia piriei

Thank for your help,
Enjoy your day

Some personal opinions:

primovulasp.jpg: appears to be a Prosimnia species, possibly P. semperi?

phenacovolvaphilippinar.jpg: I am unsure from the photograph alone, but the darkened terminals resemble Pellasimnia brunneiterma.

prosimniapirei.jpg - appears to be Prosimnia piriei.

Thank you Wei for your attention.
But how can you distinguish a Primovula of a Prosimnia ?
Enjoy your day

Hi,

Best to differentiate using the empty shell. I'm only guessing it's a Prosimnia based on living photos of P. semperi I've seen before.

Cheers!
