One folio contains a number of clusters, but they aren't necessarily all connected through proximity.
Remember the Gemini folio? There it appeared that dots on the triple line (= ecliptic) indicated that a number of constellations were skipped.
Now between Hydra-Corvus-Crater and the Beastly one, there is not only a set of dots, but also two tubes.
Let me first show what I mean with the clustering. There are basically three clusters on this folio. The Eridanus cluster (blue), the Dog-Hydra cluster (red) and the North Pole cluster, which contains both Ursae, Draco and Bootes (green).
In the attachment I've used a top view planisphere which is a bit more compact and allows me to show the clustering well.
Now in between Bootes and Hydra is the unknown one and a bunch of markers...
(Edit: this planisphere from Harley MS 647 has been shifted to have Ursa Minor on the Pole, so the Circles obviously don't match those on the Farnese Atlas)
Also, I really think the curled up animal is Draco, which was famous for being, well, curly
. As I told Sam before in this thread, the wavy line always indicates a polar circle.
Edit2: Now I see the misunderstanding, I found it weird that you considered Hydra part of the Hercules group. Hercules is next to two unrelated serpents: Draco and the one held by Serpentarius. The Hydra-Corvus-Crater group is not so close.
