The title given at the Lester S. Levy Collection of Sheet Music is LULLABY: A FAVORITE BALLAD IN THE COMIC OPERA OF THE PIRATES. Composed by Mr. Storace. (Philadelphia: Carr & Co., no date).

I think it's a good idea to have a copy of the lyrics without all those hyphens, so that it can be more easily found with a search engine:

Peaceful slumb'ring on the ocean
Sailors fear no danger nigh
The winds and waves in gentle motion
Soothes them with its lullaby,
Lullaby, lullaby, lullaby, lullaby,
Soothes them with its lullaby.

Is the wind tempestuous blowing,
Still no danger they descry,
The guiltless heart its boon bestowing,
Soothes them with its lullaby,
Lullaby, lullaby, lullaby, lullaby,
Soothes them with its lullaby, lullaby.
