... pass round the snakes! (4)
I believe the answer is:
asps
'snakes' is the definition.
(asp is a kind of snake)
'pass round' is the wordplay.
'round' indicates anagramming the letters.
'pass' anagrammed gives 'ASPS'.
'the' is the link.
(Other definitions for asps that I've seen before include "Poplars" , "Small vipers" , "Cleopatra's snakes" , "Deadly snakes" , "poisonous things" .)
