This paper analyzes the development of cooperation between Argentina and Brazil from their initial rapprochement of 1979 to the construction of Mercosur in 1991. It presents an account of cooperation that emphasizes the power and organizational interests of the armed forces and that challenges the prevailing emphases on democratization and neoliberalism. In doing so, it addresses a methodological problem for qualitative research in international relations: What can be done if our theories of why cooperation occurs affect our perceptions of when it begins? Conventional explanations of Argentine-Brazilian cooperation may be biased toward what historian Herbert Butterfield called 'Whig history,' which sees in past events associations that exist only in the present. These tendencies can alter our periodization of cases, omit or falsely reject important causal variables, and too readily confirm our preferred hypotheses, but they can also be corrected.

Four species of Pandora have been reported from southern South America: P. cistula Gould, 1850, P. braziliensis G. B. Sowerby II, 1874, P. diffissa Mabille & Rochebrune, 1889 and P. patagonica (Dall, 1915). The group has received little taxonomic attention in this area, resulting in arbitrary and wrong usage of these names, for which several contradictory synonymies have been proposed. This study provides the first revision of Pandora species living in southern South America, including photographs of the type material and descriptions of shells, gross anatomy and living animals. Out of the four species previously mentioned, P. braziliensis is here regarded as valid, including P. patagonica and P. diffissa as synonyms. The fourth species, P. cistula, remains known only from its type specimen. In addition, a new species, P. brevirostris, is described from the shallow waters of Argentina. [ABSTRACT FROM AUTHOR]
