Pericú language

Pericú is the extinct and essentially unattested language of the Pericú people who lived at the southern tip of Baja California Sur. Jesuit missionaries recognized it as distinct from Waikuri (Guaycura) immediately to the north. It was spoken in the mountainous area around the mission of San José del Cabo, on the southeastern coast from Santiago to La Paz, and on the islands off the east coast as far north as Isla San José.

Data is extremely limited, amounting to only four words and ten place names.
