'pride' is the definition.
(a pride is a group of lions)

I cannot understand how the rest of the clue works.

(Other definitions for lions that I've seen before include "Large carnivores" , "Large cats" , "multinational tourists" , "Kings of the jungle" , "Roaring cats" .)

I've seen this clue in the Evening Standard.
