In the preparation of a text-critical edition of the De anima of Cassiodorus, I have made and here offer to the public a list of the extant manuscripts known to me. These number approximately 160 and the oldest date from the ninth century. I hope shortly to publish the text and with it an adequate description and classification of the codices. Since it is too much to expect that my present list is without errors or omissions, I would be most grateful to any reader who might supply me with additional information.
