Primate is after second large bird, gold (4,5)

'primate' is the definition.
(slow loris is a kind of primate)

'is after second large bird gold' is the wordplay.
'after' means one lot of letters go next to another.
'second large' becomes 'sl' (this might be a standard abbreviation which I don't know about).
'bird' becomes 'owl' (owl is a kind of bird).
'gold' becomes 'or' ('or' is the heraldic name for gold).
'sl'+'owl'+'or'='slowlor'
'is' put after 'slowlor' is 'SLOW LORIS'.

Can you help me to learn more?
