Transfer of Exilioidea Grant & Gale, 1931 to Turbinellidae, with Descriptions of Three New Species (Neogastropoda)

Abstract

Exilioidea Grant & Gale, 1931 is transferred from the family Buccinidae to the Turbinellidae based on its radular and shell morphology. From an examination of types and representative material of E. rectirostris (Carpenter, 1864), E. kelseyi (Dall, 1908), and Plicifusus obsoletus Talmadge, 1971, it is concluded that these names are synonyms and based on a northeast Pacific species with great, clinal, latitudinal and bathymetrical variation. The East Pacific abyssal Fusus rufocaudatus Dall, 1896 is transferred to Exilioidea and three new species are described : E. indica, Indian Ocean, 2900-4040 m ; E. costulata, SE Asia, 1025 m ; E. atlantica, Gulf of Mexico, 880-3365 m.
