Hello Baileyjo246,
In the UK the MLitt is acquired after the MA as far as I know. It is a postgraduate degree, but as you probably know there are differences even between the Scottish system and the English. What I would suggest is to enquire the UK agency for international academic and professional qualifications, NARIC. I think that they should be able to tell you what the US correspondent is, and what use you can make of it in your country.
