The best guess I can come up with, is provided by the Heirloom Seed
website @ http://www.heirloomseeds.com/cucumbers.htm

I'm wondering if the cucumbers you purchased from your nursery, may
have been mis-labeled:

PAINTED SERPENT (Cucumis melo) 65 days - The slim, light green,
ribbed fruits can grow 30-75" long, but best eaten at 15 inches. The
unique fruits curl into snake-like shapes. Mild, delicious flavor!
