Notes from Linnaeus pater's zoology lectures, probably given in the late 1750s, just before the publication of Linné, Carl von. 1758. "Systema naturae". Stockholm (10th edition). Some of the specific epithets are different from the ones published in 1758, and were corrected later on with pencil annotations. Some of the classification is also different from the "Systema naturae" 10th edition (see the genus "Mustella" in particular).
