4–17, from the lower Pleistocene of Cartiera Mulino,
3D1 bed of Costa (1989), Vittoria, Ragusa, southeastern
Sicily. Paratypes 1–3 from the same locality, 3D2 bed of
Costa (1989). Paratypes 18–22 and 24–35 from the
middle to upper Pleistocene of Kyllini, northwestern
Peloponnesus, N2 and H6 beds of Garilli et al. (2005a),
respectively. Paratypes 36 and 37, same locality, from the
lower to early middle Pleistocene P3 layer of Garilli
(2005b) and from a late lower Pleistocene yellowish to
reddish sandy layer about 50 m underlying the F14 bed
of Garilli and Galletti (2007), respectively.
Another four, uncatalogued paratypes are housed in
DSTC (1 sh. from 3D1, 1 sh from 3D2 and 2 shells from
3C bed of Costa, 1989, all from the lot n° 18, as Galeo-
dina carinata (Da Costa). One more uncatalogued
paratype (ex CMRG 030/534 coll. Garilli), from the type
locality, 3D1 layer, is in coll. MF (Prato).
Etymology: The species is dedicated to my wife Ro-
saria.
Material Examined: The type material from the
lower Pleistocene of Cartiera Mulino, Vittoria, Ragusa,
SE Sicily, 18 shs, and from the late lower (1 sh., from a
reddish to yellowish sandy bed about 50 m underlying
the F14 bed of Garilli and Galletti, 2007), lower to
middle (2 shs, layer P3 of Garilli et al, 2005b), and
middle to upper Pleistocene (13 shs, layer H6; 4 shs,
layer N2) of Kyllini, Elea, NW Peloponnesus, Greece.
Habitat: In the type locality, the species was mainly
recovered from the layers 3D1 and 3D2 which were
linked to the ecotone SVMC-HP (sensu Pérès and Pi-
card, 1964) by Costa (1989). In the Kyllini sites, this
species was found in cerithids-trochids-rissoids assem-
blage linked to the present biocenosis HP, characterized
by the phanerogam Posidonia oceanica (Linnaeus) De-
lile, 1813 (See Garilli et al. (2005a); Garilli et al. (2005b),
and Garilli and Galletti (2007) for more detailed infor-
mation about the paleoecological characteristics of the
cited Kyllini strata.)
Distribution: The species has a lower to middle-upper
Pleistocene stratigraphic range, presently limited to SE
Sicily and NW Peloponnesus, being recorded from the
lower Pleistocene of Sicily (type locality) and from the
lower to upper Pleistocene deposits of Kyllini, Greece
(NW Peloponnesus).
Remarks: Alvania rosariae represents a sort of inter-
mediate form between A. carinata and A. lactea (cancel-
late form). Compared with the former taxon, it shows
some similarities in the type of intraspecific variation,
showing very inflated to quite elongate shells (compare
