For the Dorset Ooser, the folklorist John Udal wrote about it - it's in the pamphlet I can't find.....

The Melbury Osmond Ooser had a hinged jaw and a pair of bullocks horns, with a 'third eye' clearly seen between the eyebrows. There is another example of this third eye in a carving on the church at Loders, Bridport. This is another horned face, with a very clear 'third eye' (from 'Sacred Dorset on the path of the Dragon', by Peter Knight).

I've obviously put this pamphlet in a very safe place because it's not in any of the three most likely places. I'll keep looking.
