il ciesm per i cerithidae esclude le seguenti specie con le seguenti motivazioni
Cerithidae
Bittium proteum (Jousseaume, 1930)
The whole case for holding this species in Mediterranean lists (Sabelli et al., 1990) is based on a single specimen from Bardawil area figured by Barash and Danin (1977, 1992: both as Dahlakia cf. leilae ). Dahlakia leilae Biggs, 1971, in turn, was described from the Dahlak archipelago, Red Sea, together with three other species which Houbrick (1978b) considers synonymous with C. proteum Jousseaume, 1930, and which do not seem conspecific with the Mediterranean shell. Thus, there is currently no evidence for the occurrence of this species in the Mediterranean.
Cerithium caeruleum Sowerby G.B., 1855
The Mediterranean citation is based on a series of juveniles collected in Haifa Bay and identified by J. Houbrick (Van Aartsen, Barash and Carrozza (1989); the occurrence is not mentioned by Barash and Danin (1992) not by Houbrick (1992) in his revision of Cerithium; but the species exists in the Red Sea entrance of the Suez Canal (Tillier and Bavay, 1905). The Mediterranean specimen illustrated by Giannuzzi-Savelli et al., (1997, fig. 63) is Clypeomorus, although the Red Sea specimen on their fig. 62 is really this species.
Cerithium echinatum Lamarck, 1822
Indo-Pacific species which occurs in the Red Sea. The record by Barash and Danin (1986) was based on a juvenile specimen (1.5 mm) collected by diving at a depth 1-2 m near Dor by S. Arkin in September 1980 and the species was never sighted again. This record seems unreliable, given that the same collector presented several more specimens of North American origin as supposedly Mediterranean (Mienis, 2000e).
Cerithium erythraeoense Lamarck, 1822
A shell of this spectacular and unmistakable Indo-Pacific species was reported from Atlit by Haas (1937). A second shell, collected in Haifa Bay by M. Tom in 1965, was reported by Mienis (2001d). In the Indo-Pacific, C. nodulosum is found in shallow sandy depressions protected by reefs (Houbrick, 1992), and would not remain undetected, if it had really settled in the Mediterranean. The populations from the Red Sea and southern Arabia are considered a different subspecies or species, distinct from C. nodulosum Bruguière, 1789 which lives in the Indian Ocean and throughout the tropical Western Pacific.
