Annotated Checklist of Mammals of the Yucatán Peninsula, México. IV. Carnivora, Sirenia, Perissodactyla, Artiodactyla

This is the fourth in a series of papers by Jones, et al., dealing with the systematics and distributional status of mammals on the Yucatán Peninsula of México. The present contribution lists 24 native species belonging to the orders Carnivora (18 species), Sirenia (one), Perissodactyla (one), and Artiodactyla (four). Among the carnivores there are one canid, six procyonids, six mustelids, and five felids, whereas the Artiodactyla is represented by two families (Tayassuidae and Cervidae), each with two species. The Yucatán Peninsula as treated in this series of papers includes the Mexican states of Campeche and Yucatan, and the Federal Territory of Quintana Roo; physiographically the peninsula also includes portions of Guatemala and British Honduras (later known as Belize). The Recent mammals of the Mexican part of the peninsula were treated in an early work by Gaumer (1917) and sub-Recent faunas were studied by Hatt et al. (1953). The physiography and vegetation of the region have been described previously by Duellman (1965, 1966), Jones, et al. (1973), Klaas (1968), and Paynter (1955). Many specimens reported in this paper were collected in the summer of 1962 by a field party under the direction of W.E. Duellman and also by a survey team, led by J.K. Jones, Jr., that collected terrestrial vertebrates and their ectoparasites under a contract (DA-49-193-MD-2215) from the U.S. Army Research and Development Command. Also, Percy L. Clifton, field representative of the Museum of Natural History, the University of Kansas, obtained mammals on the peninsula from mid-December 1962 to June 1963. Institutions from which specimens were examined are the Museum of Natural History at the University of Kansas, the National Museum of Natural History, Washington, D.C., and the British Museum (Natural History).
