GABRIELINO. This extinct Shoshonean group of California Indians inhabited Santa Catalina island; named from the Fran ciscan mission of San Gabriel. They numbered about 5,000. They shared their arts with the adjoining Chumash of Santa Barbara channel and had developed a religion with named gods. A form of this, referring to the supreme deity Chungichnish, and making use of Datura as a vision-producing narcotic, continued to spread to neighbouring tribes until after 1850.
