The external anatomy of lambeosaurine crests is understood to be highly variable between species, but variation in their internal anatomy is less well understood. The poor understanding of taxonomic variation in internal anatomy is due in large part to data limitations, where comparisons were historically made using fragmentary specimens, or more recently using CT imaging of primarily immature specimens. Here, we provide a detailed comparison of the internal anatomy of mature individuals of the lambeosaurines\n                    <jats:italic>Corythosaurus casuarius<\/jats:italic>\n                    ,\n                    <jats:italic>Corythosaurus intermedius<\/jats:italic>\n                    , and\n                    <jats:italic>Lambeosaurus lambei<\/jats:italic>\n                    , and contrast their morphology with previously described juvenile congeners and mature\n                    <jats:italic>Hypacrosaurus altispinus<\/jats:italic>\n                    .
