THOMAS] INDIAN LANGUAGES OF MEXICO AND CENTRAL AMERICA 87 
The Sierra de Tilaran, as marked on the map of Costa Rica, extends 
along the extreme northwestern border of the district of Alajuela, 
while the volcano of Puas (or Poas) is on the extreme eastern border, 
where it joins the district of Heredia. That the Sierra de Tilaran 
formed the extreme southern boundary of the Guatusan territory is 
certain. In fact, one portion of it is named the Cerro de los 
Guatusos. It seems, therefore, that the range to which Fernandez 
refers is that which extends east and west across Heredia and the 
southeastern portion of Alajuela; but what stream is referred to by 
the name ‘“‘Barva” is uncertain (possibly it should be ‘“ Brava,” 
though this does not solve the difficulty with the limited data at 
hand). 
The statement made by Peralta in the excerpt from his pen on 
page 83 agrees with his conclusion, as stated above. The assertion 
that ‘‘to the east of the Sarapiqui, and from the mouths of the San 
Jtian on the Atlantic to the mouth of the river Matina, was the 
important province of Suerre, belonging to the Guetars,”’ is open to 
question, however; as there is no means of comparing the languages. 
Nevertheless, the writer has followed Peralta in the accompanying 
map. 
Voro 
(Synonym: Boto) 
According to all the evidence remaining on record, this tribe occu- 
pied the country south of the Rio San Juan from the river San Carlos 
to the Sarapiqui, their territory extending southward to, and proba- | 
bly across, the district of Heredia and the southern part of Alajuela. 
The writer has failed to find the data on which Peralta and 
others base the conclusion that the people of this tribe were con- 
nected with the Guetare. Carl Sapper (1: 31) speaks of them as a 
distinct tribe, although not alluding to their ethnic relations. As no 
vocabulary, not even a few words of their language, has been pre- 
served, so far as known, its affinities can be only guessed at or inferred 
from other data. Is it not possible that they were the Rama, part of 
whom Bell mistook for the Guatuso. (See p.80.) Ifhis statement was 
based on some tradition, the supposition may not be wholly gratui- 
tous; otherwise it is. On the whole it is considered best for the pres- 
ent to follow here the Costa Rican authorities, who are on the ground 
and familiar with the history of their country so far as recorded; 
hence the Voto are assigned to the Guetare territory, although not 
referred to on the map. 
SUERRE(‘?) 
It is doubtful whether the territory included under this name 
should be considered a separate linguistic area. In the extract
