Abstract
Aspects of the morphology of 11 species of Triviidae are described, including the living animal, shell, radula, mantle complex, central nervous system and reproductive system. Interspecific differences in radular morphology are important in distinguishing closely allied species. Trivia aperta, T. costata and T. verhoefi are protandric hermaphrodites while T. calvariola, T. neglecta, T. pellucidula, T. rubra, T. solandri and T. suavis are gonochoric. The elaboration of the receptaculum seminis varies between species. In T. aperta, T. calvariola, T. neglecta and T. verhoefi the receptaculum is undivided while in T. costata, T. pellucidula, T. solandri and T. suavis there are two or more lobes of the receptaculum. [Other species discussed are T. sanctispiritus and T. splendidissima.].
