ture, introduced with other molluscs for farming or<br />
with shipping (Zenetos et al., 2003). The species, C. fornicata,<br />
M. arenaria are recorded in the around of the<br />
Saronikos Gulf (Delamotte & Vardala-Theodorou, 2001;<br />
Zenetos et al., 2003, 2004b), the same area of our fin<strong>di</strong>ng,<br />
or P. phola<strong>di</strong>formis from Ewoikos Gulf. Accor<strong>di</strong>ng<br />
to Zenetos et al. (2003), the presence of these species in<br />
this region, in the vicinity of the Piraeus port, is related<br />
more to shipping as there are no marine farming activities<br />
nearby.<br />
For these raisons we think that our record of C. litteratum,<br />
based on a single shell, should be considered as occasional<br />
and probably due to shipping. Further research,<br />
carried out in the area of Saronikos Gulf, could<br />
be helpful to understand if Aegean populations of this<br />
species really exist and to eventually valuate their establishment<br />
success.<br />

segnalazioni riguardano specie non stab<strong>il</strong>izzatesi, introdotte<br />
per colture, importate accidentalmente insieme a<br />
molluschi ut<strong>il</strong>izzati nelle attività d’acquicoltura o emigrate<br />
grazie al traffico navale (per <strong>il</strong> meccanismo noto<br />
come “shipping”) (Zenetos et al., 2003). Nel particolare,<br />
le specie, C. fornicata e M. arenaria sono state segnalate<br />
nei pressi del Golfo Saronico (Delamotte & Vardala-<br />
Theodorou, 2001; Zenetos et al., 2003, 2004b), la medesima<br />
area del nostro ritrovamento, mentre <strong>il</strong> taxon P. phola<strong>di</strong>formis<br />
è stato rinvenuto nel Golfo Euboico. Relativamente<br />
a queste specie, segnalate nelle vicinanze del<br />
porto del Pireo (area priva dell’attività d’acquicoltura),<br />
l’introduzione pare molto probab<strong>il</strong>mente legata al traffico<br />
navale (Zenetos et al., 2003). Pertanto, riteniamo che<br />
anche la presenza me<strong>di</strong>terranea <strong>di</strong> C. litteratum, basata<br />
su una sola conchiglia, sia dovuta a “shipping” e debba<br />
ritenersi occasionale. Solamente ulteriori ricerche, eseguite<br />
nell’area del Golfo Saronico, potrebbero aiutare a<br />
comprendere l’effettiva presenza <strong>di</strong> popolazioni attribuib<strong>il</strong>i<br />
a questa specie e <strong>di</strong> valutarne l’eventuale grado<br />
<strong>di</strong> stab<strong>il</strong>ità.<br />
