"We ascend the lofty peaks of the Cordillera and we find an alpine species of bizcacha; we look to the waters, and we do not find the beaver or musk-rat, but the coypu and capybara, rodents of the American type."
"On these same plains of La Plata, we see the agouti and bizcacha, animals having nearly the same habits as our hares and rabbits, . . . but they plainly display an American type of structure."
"The evening was calm and still; — the shrill noise of the mountain bizcacha, and the faint cry of a goatsucker, were occasionally to be heard."
