I'm reading Levy's The Dawn of Agriculture and the Earliest States in Genesis 1-11 and thought I'd share this screenshot. Really well written and researched book. Levy cites the midrash (fn77) from:

Pirqe Rebbe Eliezer, 24. [Heb], editio princeps, Constantinople, 1514. folio 16b. Digitized Copy, Hebrew Union College, Klau Library, in the Pirqe Rabbi Eliezer Manuscript Database.
