Hi Xavier, we need some locality data. Where are the shells from?

Hi Xavier, by Naticas of Philippines I assume you mean Neritas.
#1 Nerita polita f. litterata
#2 N. undata
#3 N. chamaeleon
#4 N. histrio
#5 N. polita
#6 ? N. undata
#7 N. polita
#8 N. grossa
#9 ? N. chamaeleon f. stellata ( distorted image)
#10 Upper- N. ? signata, Lower- N. polita
#11 N. polita
#12 ? (image too distorted)
#13 ? chamaeleon/histrio
#14 ?( image too distorted)
I am no good on Mediterranean shells so someone else can do those for you.
Cheers,
Dave

Ok, since Dave cleared up the dreaded Nerites, I'll take a shot at the other page of pictures:

1. I believe this is Serpulorbis xenophorus  Habe.  The erect tube coming up from the early spiral whorls is typical.  This is Western Pacific.

2.  These do look like they could be Mediterranean, though small abalones can be difficult to identify.  I think the top two are Haliotis tuberculata  Linne., and the bottom three Haliotis tuberculata lamellosa  Lamarck.

3.  I believe this is Cardium (Vasticardium) alternatum  Sowerby, Western Pacific.

4. I think there are at least 3 species of Trochidae here.  I think they are all Gibbula species except one.  The top 3 on the left and the top 1 on the right, not sure.  The second shell on the right may be Monodonta labio  Linne.  The bottom left and 2 bottom right shells look like Gibbula magus  Line.

5.  The upper shell looks like Littorina littorea  Linne. (North Atlantic but occasionally reaches Spain).

The middle shell is a Natica.  It looks like Natica collaria  Lamarck.  West Africa. Not certain.

The bottom one is Nassarius margaritiferus  Dunker  (Western Pacific).  <span class="petit">--Last edited by Paul Monfils on 2008-08-03 20:28:07 --</span>

Paul, I have had a look at my Trochidae and I think #4 may be a mixture of Gibbula magus and G. umbilicaris with, as you say, M.labio although could it be M.turbinata?

Hi Xavier,

mediterrean gibbula are quite difficult but, in my opinion:

4) Gibbula varia (L.) + Monodonta (the specimen without umbeliculus) but I think is not mediterrean. If you are really sure that is mediterrean maybe is a Monodonta lineata, da Costa

5) Gibbula adansoni (Payraudeau) except the specimen on the left in the last row that is a G. rarilineata (Michaud)  (or G. divaricata if the base is convex see <a href="http://www.naturamediterraneo.com/forum/topic.asp?TOPIC_ID=8239" target="_blank"><!-- m --><a class="postlink" href="http://www.naturamediterraneo.com/forum/topic.asp?TOPIC_ID=8239">http://www.naturamediterraneo.com/forum ... IC_ID=8239</a><!-- m --></a> )

In my opinion there are not G. magus nor G. umbilicalis.

ciao
