–P. 781: {"SIRENIA. Halicoridae. / Manatus sp. / No specimens collected. / Native name. - "Seicu". Doubtless, a Taki-taki corruption of the English "Sea-Cow". / Manatees are exceedingly common in the Nickerie River, whence they travel to the Coronie Swamp in the rainy season. They are also met with in the further reaches of the Commewijne, Cosewijne, Saramacca and Courantijne Rivers, but they are hunted extensively and are exceedingly scarce in the other large rivers near the coast."}
