Marks of gatherings are lacking from the Callimachean portion. All the writing is in the same small and very neat hand. Ligatures abound. In the text, final letters (one, two, or three together, in full or abbreviated forms) are frequently written above those which precede them; in the same position, but in the middle of a word, α and abbreviated εν appear frequently; αι, ε, σ or ς, and abbreviated ον and ας, rarely. Iota subscr. is not regularly employed. Horizontal supralinear strokes are used 38 times to indicate names of persons. The scribe was a careful copyist. His major errors, not found in the common stock either of the manuscripts in general or of the z group, nor shared with G and H, number only 25 (permutation of letters, 7; omission and insertion of letters, 15; mis-division of words, 3); his minor, 43 (including 35 of accent).
