I have no hesitation in including in the Tupi family the Mundurucus, or Paris, on the upper Tapajoz. Their relationship was fully recognized by Professor Hartt, who was well acquainted with both dialects.[341] They are a superior stamp of men, tall, of athletic figures, light in color, their naked bodies artistically tattooed. Their women are skilled in weaving cotton hammocks, and the men pursue some agriculture, and manufacture handsome feather ornaments. To the same family belong the Muras and Turas, in the swampy valley of the Madeira in its middle course, “an amphibious race of ichthyophagi,” as they are called by Martius, savage and hostile, and depraved by the use of the _parica_, a narcotic, intoxicating snuff prepared from the dried seeds of the _Mimosa acacioides_. At the beginning of this century they were estimated at 12,000 bowmen; but this was doubtless a great exaggeration. Though their dialect differs widely from the _lingua geral_, the majority of their words are from Tupi roots.[342] Others are related to the language of the Moxos, and in the last century certain of their tribes lived in the immediate vicinity of these, and were brought into the “reductions” of the Moxos Indians by the Jesuit missionaries.[343] The tendency of their migrations has been down the Madeira. The tribes of this lineage in the extreme south of Brazil were numerous. The Guachaguis, corresponding apparently to the modern Guachis, are said by Lozano to speak a corrupt Guarani.[344] Vocabularies have been obtained by Castelnau and Natterer, which indicate only a remote resemblance. According to their own tradition, they migrated from near the Moxos in the Bolivian highlands. The Gualachos, who spread from the river Iguaza to the sea coast, spoke a Guarani dialect in which the sounds of _f_, _j_ and _l_ were present, which, in pure Guarani, are absent. They built thatched houses divided into several rooms, and raised abundant harvests.[345] The Omaguas and Cocamas, the most western of the Tupis, dwelling within the limits of Ecuador, had evidently profited by their contiguity to the civilization of Peru, as they are described by early travelers as familiar with gold, silver and copper, living in permanent villages connected by good roads, and cultivating large fields of cotton, maize and various food-plants. The art-forms which they produced and the prevalence of sun-worship, with rites similar to those of Peru, indicate the source of their more advanced culture. By some authors the Omaguas are stated to have migrated down the Rio Yupura from Popayan in New Granada, where a tribe speaking their dialect, the Mesayas are alleged still to reside.[346] The peculiar “mitred” skulls of the Omaguas are an artificial deformity prized by them as a beauty. The Tupi is rich in mythological tales which have been collected by several competent students of their tongue. (Hartt, Magalhaes, etc.) Their religion is a simple animistic nature-worship.
