Two fragments of four pages each, commonly labelled A and B, preserved in the Library of Carlsruhe.
Both are in an Irish hand.
Fragment A dates from the late 8th or early 9th century and contains parts of three Masses, one of which is pro captivis (for captives).
The arrangement resembles that of the Bobbio Missal.
Fragment B contains fragments of Masses with a Memento for the living made up of a long list of intercessions for various classes of persons.
