This article presents the administrative structure of the Samogitian diocese at the end of 1830. It constitutes the second part of a text presenting the state of the diocese in the light of the schematism published for 1831. The description of the Samogitian diocese and the previously published edition of the schematism is part of a project to show the state of the Catholic Church on the eve of tsarist repression, which began after the fall of the November Uprising. To date, schematisms of the Luck and Zhytomyr dioceses and the Kamenets diocese have been published as part of the project.
