Together the fragments form the first two and the last two leaves of a gathering (assuming one of eight leaves), and contain Mark XII, 41 to XIII, and XIV, 49 to XV, 4 almost complete. The work was written in double columns, the inner column containing the text, the outer (and narrower) containing the glosses, and further glosses have been added in a different hand in the margins. The leaves are almost complete, lacking the top margins and two or three lines of text and, in leaves 7 and 8, the outer margin and the greater part of an outer column. The leaves when complete measured approximately 11 x 8 inches.

The fragments had been used as pastedowns in a copy (pressmark K.81.c) of ‘In aedibus Aldi et Andreæ soceri’ (Venetiis, 1514), by Suidas (edited by D Chalcondyles).
