Cyclothurus didactylus. Tamanduái, L. G. The small Silky-haired Anteater,—is arboreal, and rather abundant. There is another species much smaller, and as white as cotton; but it is rare, and I never met with it.

Priodonta gigas? Tatuassú, L. G. The great Armadillo.—Rather scarce.

Tatusia septemcinctus? Tatu, L. G.—This and another very small species are the most abundant in the Amazon district, but can seldom be procured except by hunting with dogs. All the kinds are eaten, and their flesh is very white and delicate.

Didelphis ——. Opossum. Mucúra, L. G.—Several species are found. They frequent the neighbourhood of houses, and attack poultry. The young are carried in an abdominal pouch, like the kangaroos, and have their little prehensile tails twisted round that of the mother.

Hydrochærus capybara. Capywára, L. G.—This animal is found on all the river-banks. It feeds on grass, and takes to the water and dives when pursued. It is sometimes eaten, but is not considered very good.

Cœlogenis paca. Páca, L. G.—This animal is generally abundant. It is nocturnal, and is much esteemed for its meat, which is the very best the country produces, being fat, delicate, and very tender.

Dasyprocta nigricans, Natt. Black Agouti. Cotía, L. G.—This species is found on the Rio Negro.

D. punctata? Yellow Agouti.—This is probably the common Amazon species.

D. agouti? Cotiwya, L. G.—A smaller species, very widely distributed. All are eaten, but the meat is rather dry and tasteless.

Cercolabes prehensilis. The Brazilian Porcupine.—This animal is scarce. It is eaten by the Indians.
