title: A snail in the long tail: a new Plekocheilus species collected by the 'Comisión Científica del Pacífico' (Mollusca, Gastropoda, Amphibulimidae).
abstract: Among the historical collection gathered by the 'Comisión Científica del Pacífico' during 1862-1865, type material was found of one of the species described on the basis of the material collected shortly afterwards. Inspection of the types revealed that only one specimen may be considered as type material of Bulimusaristaceus Crosse, 1869; this specimen is now designated as the lectotype. The other specimens are described as a new species, Plekocheilus (Plekocheilus) cecepeus.
