AuthorshipSCIMAGO INSTITUTIONS RANKINGS

    Abstracts

    The occurrence of a mollusc of the family Lymnaeidae is recorded for the first time in Brazil north of parallel 15ºS, as a result of the finding of Lymnaea columella in Manus and Benjamin Constant, state of Amazonas. A description is given of its shell, renal organ, genital system and radula, pointing to the morphological characteristics of diagnostic value to separate it from two other species previously studied by the author, Lymnaea viatrix and L. rupestris, which also occur in Brazil.
