What is "cryptoconchoidsyphonostomata"

Cryptoconchoidsyphonostomata, or While it's to be Had was a one-act play styled a "successful romantic Extravaganza", written by R. H. Edgar and Charles Collette, an actor who also starred in the leading role of Plantagenet Smith and wrote the words and music of the play's hit song. It is chiefly remembered today as the curtain-raiser at the Royalty Theatre on the night of 25 March 1875, the night of the premiere of Gilbert and Sullivan's first opera produced by Richard D'Oyly Carte, Trial by Jury.
