Three specimens of Lagenodelphis hosei, a dolphin mostly found on tropical waters, were found on the coast of Rio Grande do Sul, Brazil, approx. 32 S, 52 W. This dolphin has never been recorded in these latitudes, for at least 20 years. During this time, our laboratory (Marine Mammals Lab, FURG) has been doing systematic beach surveys along 120 km of beach, and this species has never been found. Two specimens were found by us, and the third (which was chronologically the first) was collected by GEMARS-Porto Alegre.--Andre S. Barreto <posasb@super.furg.br>.
