> There are the "apocrypha" of the "Old Testament" in the narrow sense, which are those parts nowadays excluded by the Protestants.

Given the pejorative connotations of "apocrypha", Catholics don't accept that term for the books in their OT canon which are rejected by Jews and Protestants – they say the appropriate term is "deuterocanon" ("second canon"). Catholics do use the term "apocrypha" for books of similar antiquity (such as Enoch) which ended up being rejected from the Catholic canon. Many Protestants prefer to call those later books "pseudepigrapha", to avoid confusion with the books of the Protestant apocrypha / Catholic deuterocanon; however, in the strictest sense of the term, that's not entirely correct, since "pseudepigrapha" literally refers to false claims of authorship, and while most of these texts do make such false claims, some of them are instead anonymous.
