    Lavori - Soc. Ven. Sc. Nat. - Vol. 29: 109-117, Venezia, 31 gennaio 2004 THE EOCENE DECAPOD CRUSTACEAN FAUNA OF THE "MAIN" QUARRY IN ARZIGNANO (VICENZA - NE ITALY) WITH THE DESCRIPTION OF A NEW SPECIES OF RANINIDAE CLAUDIO BESCHIN*, ALESSANDRA BUSULINI**, ANTONIO DE ANGELI***, GIULIANO TESSIER** Key words: Crustacea, Decapoda, Raninidae, Eocene, NE Italy. Abstract The Eocene crustacean fauna found in the "Main" quarry of Arzignano (Vicenza - NE Italy) has been studied for twenty years and the number of species is still increasing. Up to now the known species are 53 and belong to 20 families: Callianassidae, Albuneidae, Diogenidae, Dromiidac, Dynomenidae, Raninidae, Calappidae, Hepatidae, Majidae, Dairidae, Parthenopidae, Retroplumidae, Cheiragonidae, Portunidae, Carpiliidae, Goneplacidae, Pilumnidae, Xanthidae, Palicidae and Grapsidae. The new discovery of a very well preserved specimen of great size has allowed the creation of Lophoranina maxima sp. nov. and a better placement of the specimens previously known as L. cf. reussi. The new species is characterized by the number and the distribution of the transverse ridges on the dorsal surface of carapace and the shape and distribution of the little spines on the ridges which vary in the different phases of growth. The genus Lophoranina is widely spread in the Eocene deposits of Veneto. The great size of the studied specimen let us say that L. maxima sp. nov. is the greatest fossil Raninidae that has ever been found. Riassunto La fauna eocenica a crostacei decapodi delta cava "Main" di Arzignano (Vicenza - Italia nordorientale) con la descrizione di una nuova specie di Raninidae. La fauna a crostacei di eta eocenica rinvenuta nella cava "Main" di Arzignano (Vicenza - Italia nordorientale) viene studiata ormai da vent'anni e si arricchisce continuamente di nuove forme.

SQUIRES Department of Geological Sciences, California State University, Northridge 91330 ABSTRACT—Rare specimens of the nautiloids Nautilus and Aturia and extremely rare specimens of a sepiamorph sepiid are described from the late Eocene Hoko River Formation, northern Olympic Peninsula, Washington. The well-preserved partial phragmocones are from channel-fill clastics deposited on the inner and middle slopes of a submarine-fan system. The Nautilus specimen is allied to N. cookanum Whitfield from middle Eocene strata, New Jersey, and is probably conspecific with Nautilus sp. (Miller) from late Eocene strata, northwestern Oregon, both of which were previously assigned to Eutrephoceras. This is the first record of Nautilus in the northeastern Pacific. The Aturia specimen is tentatively identified as A. cf. A. alabamensis (Morton), a species previously only known from late Eocene strata in the Atlantic-Gulf Coastal area and northeastern Mexico. Aturia alabamensis may be the same as numerous Eocene North American aturiid species. The two sepiamorph sepiid specimens resemble Belosepia Voltz but are probably generically distinct.

The development of an anomaly concerning Zanthopsis unispinosa, also present, if not peculiar to the island, is well established. A carapace of Harpactocarcinus sp. from this horizon is the first British record for the genus. Late Eocene species new to the island are Goniocypoda quaylei Crane, Orthakrolophus depressus? (Quayle and Collins) and Typilobus belli Quayle and Collins. Three new genera and species are described from the Late Eocene Headon Hill Formation; a callianassid, Vecticallichirus abditus; a goneplacid, Gonioplacoides minuta, and a hexapodid, Headonipus tuberculosus. New, superior material of the Late Eocene species, Typilobus obscurus Quayle and Collins, from the type locality, Colwell Bay necessitates a new description. A table of all known Tertiary species of decapod crustaceans from the Isle of Wight is appended.

Morphological details unknown for previously described species are included. New systematic placements are offered based on recent research. Intraspecifi c morphological variation is documented for the goneplacoid crab Tehuacana americana. Costacopluma texana is the second Paleogene species of that genus in southeastern USA, and because of its abundance represents the most completely described species for the genus.
