Earthling's ill nature dealt with (9)

I believe the answer is:

tellurian

'earthling's' is the definition.
(synonyms)

'ill nature dealt with' is the wordplay.
'dealt with' indicates an anagram.
'ill'+'nature'='illnature'
'illnature' with letters rearranged gives 'TELLURIAN'.

I've seen this clue in The Independent.
