Note 66 — ACT II., SCENE I.
Reading edition
The trundletail was a species of dog in little estimation, I believe; it is mentioned in the "Lear" of Shakespeare. So Ursula to Quar. in "Bartholomew Fair:" "Do you sneer, you dog's-head, you trundletail!" But here the host only puns on the rolling or trundling the bowl at the game.
