This is just to the northwest of Rath Croaghan, it is described as a a fallen four-sided standing stone, 2.78m in length, it has an unusual name maybe some of the language experts might be able to help.
Misgaun Meabh is the old name for Maeve's Cairn on Knocknarea, not sure how it got transplanted here! There's also a Milleen Meva, Meva's Hillock around there somewhere. Dont know if its the same person!
