Among the independent Chaco stocks, D’Orbigny classes the Lenguas, who in 1828 lived, about 300 in number, near Corrientes.[512] Von Martius believed they were a branch of the Guaycurus.[513] There is ample evidence, however, that they were a wandering branch of the Chiquitos of Bolivia. The missionary, J. P. Fernandez, who visited them about a century before D’Orbigny, says expressly that they spoke the same tongue as the Chiquitos;[514] and the statement of Hervas that the similarities of their words to the Chiquito arose from borrowed expressions is not well founded.[515]
