Cavia porcellus (Linnaeus, 1758). Syst. Nat., 10th ed., 1:59. TYPE LOCALITY: Brazil, Pernambuco (questionable). DISTRIBUTION: Domesticated worldwide; possibly feral in N South America. SYNONYMS: anolaimae, cobaya; cutleri Bennett, 1836; leucopyga Cabanis, 1848; longipilis. COMMENTS: Husson (1978:451) reserved the use of porcellus to denote domesticated guinea pigs, which are probably derived from tschudii (Corbet and Hill, 1991:201), but also see Hiickinghaus (1961:96), who regarded porcellus as a synonym of aperea. This species may be a domesticated animal with no established wild population. K. F. Koopman (pers. comm.) believes that N South American populations may be feral domestic guinea pigs; but see comment under aperea.
