Psalter with various rites and without supplement. Contains prayers read before the Psalms, the text of the Psalms (leaf 4b), biblical odes (leaf 151a) and canon of supplication to the Theotokos in the eighth mode (leaf 161b). Leaf 1b, a 16th cent. binder's inscription. Insignificant marginal inscriptions on leaf 33b. Pen-testings along the right margin on leaves 57a, 59b-60a, 64b, 113b, 125a and on the leaf which was later cut off and used for patching this manuscript. This is evident from the remnants of other pen-testings and exercises in drawing headings on leaves 85b, 116a-116b, 119a, 120b, 12b. In the upper margin traces of an erased inscription. Ornamented headings and initial.
