These rock barnacles are common elements of tropical American faunas, and otherwise range northward only to Cape Hatteras in the northwest Atlantic. Hence, it can probably be assumed that the Stomatolepas on Nova Scotian leatherbacks also settled in warmer waters, perhaps of the Antillean-Caribbean region, and that subsequently the turtles migrated northward to the area of their capture. Many herpetologists would be particularly interested in knowing whether marine turtles captured off the coast of Europe are ever "tagged' with Caribbean barnacles. We wish to acknowledge the aid of Dr. David K. Caldwell, Los Angeles County Museum, Los Angeles, California in providing information on the migrations of tropical American turtles; and the Ford Foundation for their support of the preparation of this paper through a grant to the Systematics- Ecology Program.
