Some notes on reproduction in the Patagonian Mountain viscacha, Lagidium boxi (Mammalia: Rodentia)



The material consists of the ovaries from a pregnant female and observations on a live female of the Patagonian species of Mountain viscacha (Lagidium boxi). The study is reported because it shows that L. boxi, like the Peruvian Mountain viscacha (JL. peruanum), appears to ovulate only from the right ovary (Pearson, 1949). Features of the material are compared with information known for other hystricomorph rodents.
