Ungulate roamed freely with no rain around (9)
I believe the answer is:
dromedary
'ungulate' is the definition.
(dromedary is a kind of ungulate)
'roamed freely with no rain around' is the wordplay.
'freely' indicates an anagram.
'with no rain' becomes 'dry'.
'around' is an insertion indicator.
'roamed' anagrammed gives 'romeda'.
'romeda' inserted inside 'dry' is 'DROMEDARY'.
(Other definitions for dromedary that I've seen before include "Kind of camel" , "Arab racer" , "Creature" , "Animal" , "One-humped camel bred for riding" .)
