I think this is one of the toughest elements of You are not allowed to view links. Register or Login to view. to identify. Judging by its position in the folio, I am disinclined to think that it depicts any object graphically with the purpose to illustrate any concepts of the text.
It does not look as a separate illustration, rather it is firmly built into the line of the text. It does not look specific, it is a very general shape. All this is quite the opposite as compared with the objects in the left margin. They are elaborate, detailed, separated from the text and framed together, and feature a label for what I consider to be abomasum.
I see no evidence to logically link the round shape on the right with the imagery on the left - in the first place because they are not spatially linked.
Hence my tentative guess would be that the circular shape serves as a sign rather than illustration. In its potential capacity of a sign, it resembles an amulet with a rope, to be worn on one's neck. This is in agreement with wearing medieval (and not only those) charms on the neck. In other words, this may be a modus operandi sign.
Another option for me is that the "o" is a correction or abbreviation. The dotted line should be explained in this regard, which is not simple.
