Recent analyses of exchange in the structure of Papua New Guinea societies have focussed predominantly on competitive or ceremonial forms of reciprocity, such as the Moka, Tee, and Kula, rather than the complex, multigenerational exchange relationships that marriages commonly establish between wife-giving and wife-taking groups. One consequence of the neglect of affinal in favor of ceremonial exchange is that it is difficult, if not impossible, to determine for many otherwise well-described societies what affinal transactions take place, how they are related to such other aspects of social structure as the extensive negative marriage rules characteristic of this region, and in those societies where competitive systems are found, how the ceremonial and affinal aspects of exchange are articulated. To take one of several possible examples, Feil (1984) reports that the Tee competitive exchange system of the Tombema Enga is built upon and interdigitates with a base of affinal exchange relationships. But Feil is ambiguous as to whether affinal and competitive exchange are distinguishable institutions or a unitary phenomenon. For instance, he states that exchange partners in the Tee are invariably conceptualized as affines--i.e., as linked by a marriage (e.g., Feil 1984:101, 156)--but he also states that not all affines are exchange partners (Feil 1984:102, 127-8). What is not clear from Feil's various reports is whether affinal transactions ever take place outside the context of the Tee and, if so, to what extent; whether some categories of affines are more likely to be chosen as exchange partners than others and on what grounds; and what the implications are for kinship relationships generally of passing over particular affines (including matrilateral relatives) as exchange partners in the Tee. In contrast to many recent Papua New Guinea ethnographers, however, Feil (1980) provides a detailed account of the wide-ranging Tombema marriage prohibitions, and how these are related to the structure of the competitive exchange system. This paper has two aims. The first is to contribute to the ethnography of affinal exchange systems in New Guinea by describing the cross-generational exchange relationships and wider alliances that marriages establish between individuals and groups in one lowland Papua New Guinea society. The structure of these alliances shows a striking similarity to those underlying affinal exchanges in many other Papua New Guinea societies and points to some very widespread but largely neglected similarities in the structures of both lowland and highland social systems (but see Rubel and Rosman 1978). It is beyond the scope of this article to examine these similarities in detail, but I will allude to some of the most basic in the discussion of two highland societies in the conclusion.
