Full title: 'Fresh water Turtle | commonly called | Soft Shelled Turtle'.
Description of a big edible turtle living in the Savannah and Alatamaha rivers, as well as the rivers of East Florida.
In the handwriting of an amanuensis, except for the address on the last page ('Sir Charles von Linné Archiater to His Majesty the King of Sweden & Knight of the Polar Star'), which is probably in Alexander Garden's hand.
See letter from Alexander Garden to Carl Linnaeus, 20 June 1771 n.s., "The Linnaean correspondence", linnaeus.c18.net, letter L4515.
In his annotated copy of Linné, C. v. "Systema naturae". 1766. 12th edition, Linnaeus has entered annotations which might refer to this turtle.
