JICARILLA, a tribe of North American Indians of Athapascan stock, originally occupy ing portions of Arizona and New Mexico but now settled on a reservation near Tierra Amarilla in northern New Mexico. The tribe at one time comprised two bands, the Llanero and the 011ero, ranging on different banks of the Rio Grande. The name is sup posed to be of Spanish origin, from a basket tray, the tribe being famed for its skill in basket weaving. At one time they were the terror of their district, but they now live quietly although they remain uncivilized. Their language is similar to that of the Apaches and they are believed to be an offshoot of that tribe although they maintained their independent ex istence. The tribe is steadily decreasing, now numbering less than 700.
