Representing Nepal, the largest living land animal (8)
I believe the answer is:
Here is my best explanation:
'largest living land animal' is the definition.
(I've seen this before)
'representing nepal the' is the subsidiary indication.
'representing' indicates anagramming the letters (letters must be re-presented in a new way).
'nepalthe' anagrammed gives 'elephant'.
(Other definitions for elephant that I've seen before include "The plane (anag.)", "The animal that never forgets", "Large animal (in the room?)", "See 18", "bigger one from two continents?", "Very large animal", "jumbo", "Get this animal from Pat and Helen", "Trunked mammal" and "Large pachyderm".)
