James is said to have been the 'Catholike Divine' who edited, with preface and notes in English, the tract entitled 'Fiscus Papalis; sive, Catalogus Indulgentiarum & Reliquiarum septem principalium Ecclesiarum urbis Romæ ex vetusto Manuscripto Codice descriptus,' London, 1617; another edition, 1621, was accompanied by the English version of william Crashaw. In 1608 James edited John Wycliffe's 'Two short Treatises against the Orders of the Begging Friars.' Four of his manuscripts are in Lambeth Palace Library: 1. 'Brevis Admonitio ad Theologos Protestantes de Libris Pontificorum caute, pie, ac sobrie habendis, legendis, emendis,' &c.
2. 'Enchiridion Theologicum, seu Chronologia Scriptorum Ecclesiasticorum, ordine alphabetico,' &c.
3. 'Suspicionum et Conjecturarum liber primus, in quo ducenta ad minus loca SS. Patrum in dubium vocata, dubitandi Rationes, Rationum Summæ perspicue continentur.'
4. 'Breviarium Episcoporum totius Angliæ, seu nomina, successio, et chronologia eorundem ad sua usque tempora.' In the Bodleian Library (Bodl. MS. 662) is his 'Tomus primus Animadversionum in Patres, Latinæque Ecclesiæ Doctores primarios.' Two letters from James to Sir Robert Bruce Cotton, dated 1625 and 1628, are preserved in Cotton. MS. Julius C. iii., ff. 159, 183. Bodley's letters to James are in 'Reliquiæ Bodleianæ,' published by Thomas Hearne, from Bodleian MS. 699, in 1703.
