Satyr's kin (4)
I believe the answer is:
faun
'satyr's kin' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for faun that I've seen before include "Roman goat-like deity" , "Roman deity, in the form of a man with a goat's horns, legs and tail" , "Rural deity, half-man, half-goat" , "mythical deity" , "Mr Tumnus or his ilk" .)
