For Central and South America the data, from a cursory inspection, seem somewhat more adequate, though we must eagerly await a more thorough-going survey of this region than can at present be offered. The Miskito of Nicaragua call the mother’s sister _yaptislip_, which is merely a modification of _yapti_, mother, but while the father’s brother, _urappia_, is classed with the step-father, he is distinguished from the father, _aisa_. At all events, there is a distinctive term for maternal uncle, _tarti_, and correlatively a special designation, _tubani_, for the sister’s son (man speaking). For the father’s sister our authority gives only a descriptive term: _saura_ may be the correlative term, but it is simply translated ‘brother’s child’. Of the four terms for cousin, one is descriptive (child of brother or sister), two coincide with the regular words for _Geschwister_, the fourth is unfortunately not clearly defined so that its application to the cross-cousin, which would conform to Dakota usage, remains problematical. The terms of affinity are interesting inasmuch as the principle of reciprocity appears here. Thus, _dapna_ means both father-in-law and son-in-law, and the same descriptive expression, oddly enough, is applied to the mother-in-law and daughter-in-law in female speech.[19] The former instance of reciprocity recurs among the Chibcha of Colombia and we may thus have here another case of the geographical localization of kinship features. The Chibcha list supplied by one of Morgan’s informants,[20] imperfect though it is, records some suggestive facts. The term for father’s brother seems only a variant of the word for father, and is clearly distinct from that for maternal uncle. The designations for both kinds of aunt are doubtful. In the speaker’s generation ‘parallel’ male cousins, _i.e._, the sons of two brothers and of two sisters, are grouped with brothers and distinguished from cross-cousins, as they are in the Dakota system. That a woman calls her father’s sister’s son by the same term as her husband is a fact of some theoretical importance since it suggests the possible occurrence of cross-cousin marriages.
