3 Gastropods from Portugal - mikede - 01-23-2008

I've got these 3 beached specimens from portugiese coast near Lisbon. I could only identify them to the family level (and I'm not sure even this identification is right).
1) Naticidae sp.(ca 5mm)

2) Muricidae sp. (ca 8mm)

3) Turridae sp.? (ca 10mm)

Thanks,

Hello.
Number 2 is a coralliophila. Maybe a coralliophila  lamellosa (Bivona And., 1838), but the exact identification it's difficult because of the poor condition of the shell.

Thanks! Any guesses about the other 2 shells?

Naticidae has a really strange colour. May you post a picture of the other side (with the aperture, columella, umbiliculus etc.)?

About the turris I can't help you. Mediterrean Turridae are almost impossible for me!

Thanks for your help ale.v!

I finally managed to take some pictures of the small Naticidae and of some other European shells missing a "sure" identification (for later posting, don't want to bother you and others with too many shells <img src="images/smiley/smile.gif" alt="" border="0" /> ). It was sometimes really hard, had to hold the shells in my fingers to have them stay in the right position <img src="images/smiley/smile.gif" alt="" border="0" />.

So here come two more pictures of the strange Naticidae

Nothing really like it I can see. The nearest I can get is Lunatica guillemini ( Payraudeau, 1826) , but this is usually dark brown not black. Has it been stained by mud? The only other thing I can think of is perhaps it is a West African species that has strayed far North,or an accidental import from elsewhere.
Incidentally, if you want to hold something steady to photograph it use Blu-tack or something similar, it works really well.

It would be possible that the shell got stained by mud, but I don't know how I could test/prove it. The other shells I found on the same spot were all clean.

Just in case someone is interested: I think I found out the species of the turridae shell. This could be a Crassopleura maravignae, here a pic of this species <a href="http://elrinconmarinosgasteropodos2.iespana.es/Fotos%20coleccion/Turridae/Crassopleura%20maravignae.jpg" target="_blank"><!-- m --><a class="postlink" href="http://elrinconmarinosgasteropodos2.iespana.es/Fotos%20coleccion/Turridae/Crassopleura%20maravignae.jpg">http://elrinconmarinosgasteropodos2.ies ... vignae.jpg</a><!-- m --></a>

As Dave r told you, the naticidae should be a Euspira guillemini (Payraudeau 1826) with an uncommon black colour (my books report the Euspira genus).

About the turridae I found strange the white-brown colouration. Look at this page (in italian) for a good review of the mediterrean turridae:

Yes this turridae page was not unknown to me. It's really a nice turridae compilation, pity I don't have much turridae species.

On another page I found a pic of a worn specimen of Crassopleura maravignae and it looked pretty much alike as my shell. I gave a link to the picture in my previous post, but somehow the link won't work.
