【 摘 要 】

In May 1987, a female of Bothrops jararaca (Wied, 1824), from Carazinho, Rio Grande do Sul (RS), Brazil, was placed in the same vivarium with a male of Bothrops neuwiedi Wagler, 1824 coming from Guaíba, RS. There, they stayed for aproximately ten months. In March 1988, it was observed a delivery of five live and two still born, among them six presented morphologic characteristics of B. neuwiedi and one of B. jararaca. After the female died, in April 1988, through necropsy, two fetusus were found, one near the cloaca and, both identified as B. neuwiedi. The morphologic analysis and the origin of the progenitors suggest the hypothesis that the litter was resulted of cross-breeding.
