–Allen 231. First ed., Madrid, 1741. Various later eds. Manati, 1, chap. 21: 225-228 or 319-327?, pl. 2 (reproduced in Durand, 1983: 91-96, 175). Gives an interesting description of the morphology, behavior, and hunting of Trichechus manatus in the Orinoco region. Gumilla's account is particularly noteworthy for his eyewitness observation of a female manatee with twin fetuses; this was the first, and for over two centuries the only, evidence of twinning in sirenians.
