College of Arms - Arms of FitzGerald, Duke of Leinster lyrics

Argent, a saltire gules. Mantling— gules and argent. Crest— On a wreath of the colours, a monkey statant proper, environed about the middle with a plain collar and chained or. Supporters—On either side a monkey environed and chained, as in the crest. Motto—"Crom a boo."
