Abstract

Papyridea clenchi spec. nov. (Cardiidae) is described from Martinique and compared with the related Papyridea lata (Born, 1778), Papyridea soleniformis (Bruguière, 1789) and Papyridea semisulcata (Gray, 1825). Papyridea curvicostata spec. nov. is described from Ecuador and compared with the related Papyridea hiulca (Reeve, 1845), Papyridea crock­eri (A.M. Strong & Hertlein, 1937) and Papyridea aspersa(G.B. Sowerby i, 1833). Taxonomic relations within the four tropical Atlantic and four tropical eastern Pacific species are analyzed. Distributions of the living species are given. Atlantic-Pacific geminate species pairs are discussed; a pre­dominantly one-way migration (from Atlantic to Pacific) through the Isthmus of Panama is hypothesized. The fossil record of Papyridea is reviewed and the taxonomic position of Profulvia is discussed.

Abstract

Critical remarks are made on Drymaeus species, reported from Peru in a study on land snails from National Parks at the eastern side of the Andes. Four of these species (Dry­maeus multilineatus, D. coniformis, D. glaucostomus, all known from Venezuela or Central America, and D. geomet­ricus, known from Colombia) appear to be misidentified as Peruvian species, which thus may lead to incorrect biogeo­graphical interpretations. Correct identifications are given for all the disputed Drymaeus species. Bulimulus (Bulimu­lus) inconspicuus F. Haas, 1949, is now transferred to Dry­maeus (Mesembrinus). Additionaly, a new species, Drymae­us (Drymaeus) verecundus Breure & Mogollón, is described.
