The Apocrypha that was originally in the KJV and the versions before it were called The Apocrypha Proper.
The Apocrypha in the King James Bible contained fourteen books.
1 Esdras, 2 Esdras, Tobit, Judith, The rest of Esther, Wisdom, Ecclesiasticus, Baruch - with the Epistle of Jeramiah, Song of the Three Children, The Story of Sussana, The idol Bel and the dragon, The Prayer of Manasses, 1 Maccabees, 2 Maccabees.
These books cover the intertestamental period between the Old and New testaments.

"7. Such Quotations of Places to be marginally set down as shall serve for the fit Reference of one Scripture to another."
