PIMA 
The Pima are scattered, as shown by the map, in five isolated 
groups, as follows: | 
Pima Alto (Upper Pima). 
Pima Bajo (Lower Pima). 
Potlapigua. 
Pima of Bamoa. 
Tepehuane colony. 
Pima Alto.—As the Indians of this group are confined chiefly to 
the United States and are referred to in the Seventh Annual Report 
of the Bureau of American Ethnology, and as the area is marked on 
the linguistic map accompanying that Report, it is unnecessary to 
discuss them here. 
Pima Bajo.—The Lower Pima extended east and west along the 
lower middle portion of the Yaqui river, joining the Tarahumare on 
the east, the Opata on the north, the Yaqui on the south, and the Seri 
on the west. These are substantially the boundaries given by Orozco 
y Berra, and are based chiefly on the position of villages in which 
the Piman language was spoken. However, the evidence in regard 
to the narrow strip extending along the south bank of the San José 
river to the Gulf, as shown on the map, is not entirely satisfactory. 
It is also possible that the eastern boundary has been carried a 
short distance into the Tarahumare territory. 
Father Ribas (870) mentions as pueblos of the Lower Pima: Como- 
ripa, Tecoripa, Zuaque (Suaque), and Aivino. The last two deter- 
mine the extreme northern boundary as given by Orozco y Berra, 
while the first was located on the Yaqui river not far from the south- 
ern boundary. His statement (358) that the pueblos of the Movas, 
Onavas, and Nuri belonged to the Upper Pima must be a misprint 
or a clerical error, as they were certainly situated in the territory of the 
Pima Bajo, and he must have known this; however, there is further 
mention of this point below. The situation of the Nuri pueblo deter- 
mines the extreme southern point of the area in the map, and Nocori 
the northwestern extension. However, the pueblos of Yepachic and 
Tonachic in the eastern part of the territory, as laid down by Orozco y 
Berra, appear, from the termination of the names, to be of Tarahumare 
origin, and this supposition seems to be confirmed by the statement 
of Juan Ortiz Zapata (340) that these two pueblos were included 
among the Tarahumare missions. A slight change from Orozco y 
Berra’s eastern boundary line has therefore been made to correspond 
with this evidence. Though the Pima language may possibly have 
been spoken at these two missions, the names betray the fact that 
the pueblos were originally Tarahumare. 
Potlapigua.—An isolated group of Pima, named Potlapigua, is men- 
tioned by Orozco y Berra (1: 348) in the region of Babispe, on the
