Reg. lxxx. § 22.  Fessler (De Pat. Sæc. iv. p. 514) notes the similarity of a Homily, De perfectione vitæ Monachorum, published under the name of St. Basil in a book published by C. F. Matthæi at Moscow in 1775, entitled Joannis Xiphilini et Basilii M. aliquot orationes.  He describes it as quite unworthy in style of St. Basil.
