Los resultados científicos de las excursiones de estudio realizadas a principios de 1937 han sido importantes, como así también las colecciones efectuadas, no sólo por el número de ejemplares, sino por las observaciones realizadas al obtenerlos, según el hábitat, la estación, el estado de los individuos, etc. El estudio de los materiales del Museo comparativamente con los ya catalogados permite elaborar contribuciones que se darán a conocer progresivamente o al tiempo que este informe, de caracter general, para satisfacer el deseo de la Dirección del Instituto de que sé de cuenta sobre los viajes efectuados.

In 1979 at the request of the Comision Permanente del Pacifico Sur, staff members of the Inter-American Tropical Tuna Commission prepared synopses of eight species of scombrid fishes. These are to be published in Spanish in Revista de la Comision Permanente del Pacifico Sur, number 11, in 1980. This volume contains English versions of those synopses. The Spanish and English versions are not identical, however, the latter having been updated and somewhat modified after the Spanish versions were submitted for publication. These synopses follow closely the format prepared by Rosa (1965) for the synopses to be published by the Food and Agriculture Organization of the United Nations and cooperating organizations. However, instead of preparing detailed taxonomic reviews of the individual species, the taxonomic information for all of the scombrids and billfishes has been put into a separate chapter.
