farther west, in their ancient territory. This people is disappearing 

 through vohnitary amalgamation with the Mexicans. "> 



The still numerous Yaqui remained centered along the lower Rio 

 Yaqui until a comparatively recent date, but they are now scattered 

 over the larger part of southern Sonora. Physically the tribe is 

 related to the Pima, but it contains some Mayo and other admixture. 



The Mayo, the largest tribe of Sonora, occupy practically the same 

 region as they did in the sixteenth century — the lower part of the 

 Mayo valley and much of ancient Ostimuri. 



The Tarahumare are a populous tribe of Cliihuahua, and are still 

 in a primitive condition. They live in the barrancas and lower lands 

 of a very rugged country situated largely in the Sierra Madre. 

 Numerous families inhabit caves during at least a portion of the 

 year. 



The Tepehuane, or, as they call themselves 0-o-dani, the tradi- 

 tional invaders who formerly ranged over the territory from southern 

 Chihuahua through Durango to Jalisco and Tepic, now consist of 

 two moderately large groups of about equal size, one in the extreme 

 north and the other in the extreme south of their former territory. 

 Tile northern group, of which but little was seen, is concentrated 

 mainly in the district of Guadalupe y Calvo, but scattered families 

 are found in the mountainous country along the Rio Colorado and 

 thence southeastward as far as the dependencies of Santiago de 

 Papasquiaro. The center of the southern Tepehuane domain is the 

 rough, elevated, healtliful region in southern Durango, southwest of 

 Mezquital, about the tributaries of the river of the same name. The 

 principal settlement in this district is Huktir, or, as it is more com- 

 monly known, Santa Maria de Ocotan.^ 



The Tepecano, a small but interesting tribe, probably a branch of 

 the Tepehuane, live at and about Askeltan, in' the valley of the 

 Rio de Bolanos. A small contingent of the tribe within recent times 

 has settled farther south, near the Rio Santiago. "^ 



The Huichol occupy the rugged sierra in the state of Jalisco, 

 between the country of the Tepecano and that of the Cora. They 

 live most'-y in scattered rancherias, but in winter and during cere- 

 monies they assemble at a number of villages, the principal of which 

 are Santa Catarina, San Andres, and San Sebastian. 



The Cora r.re scattered from the northern part of the territory of 

 Tepic to near the Rio Santiago, mostly west of the Rio Jesus Maria.

6 Other southern Tepehuane villages are Joconostla, Calendaria, Temoaya, Teneraca, Tascaringa, 

 San Francisco, or Koshweglim, and San Francisco de las Lajas. In addition, come Tepehuane are 

 settled with Indians speaMng the Nahua and some whites in Pueblo Viejo Pueblo Nuevo, and Mil- 

 pillas Grande, with Milplllas Chico, in Tepic.
