Throw person in charge a reptile (10)

I believe the answer is:

chuckwalla

'a reptile' is the definition.
(chuckwalla is a kind of reptile)

'throw person in charge' is the wordplay.
'throw' becomes 'chuck' (chucking is a kind of throwing).
'person in charge' becomes 'walla' (I've seen this before).
'chuck'+'walla'='CHUCKWALLA'

I've seen this clue in The Guardian.
