Bibliography and Index of the Sirenia and Desmostylia

FRONTISPIECE.—The earliest illustration of a sirenian to be published: the West Indian manatee, from the 1535 edition of La Historia General delas Indias by Gonzalo Fernández de Oviedo y Valdés. The slightly different woodcut that has been reproduced several times as the earliest figure of the manatee is actually from the 1547 edition.
