Strepsiduridae View in CoL (= Strepturidae Cossmann, 1901)

The neogastropod family Strepsiduridae (Early Eocene to Recent) contains mostly species with a single terminal varix, including species of Strepsidura and the Pliocene to Recent genus Melapium ( Vermeij, 1998) . A Late Eocene species from Colombia described as Peruficus olssoni by Clark in Clark & Durham (1946) and tentatively assigned to Streptostyla by Woodring (1973), has a subterminal varix placed either 180° or 270° from the outer-lip varix in the two specimens of the type lot examined by GJV at the University of California Museum of Paleontology, Berkeley.
