From Douglas, e.g. (4)

I believe the answer is:

manx

(Other definitions for manx that I've seen before include "Kind of cat" , "Celtic language, relating to the Isle of Man" , "Isle of Man's language" , "From an isle in the Irish Sea" , "Breed of tailless cat" .)

I've seen this clue in The Guardian.
