The feline fauna of the major portion of the United States is poor in number of species, for only the bobcat, Canada lynx, and cougar are its normal members. South of our boundary several other species occur, so that Central and South America have a richer share of this interesting family. Four of these southern species at times cross or have crossed our borders, and are thus to be considered as rare regular or occasional members of the fauna of the United States. Due to the nature of their habits these four members of the genus Felisthe jaguar, the ocelot, the margay, the jaguarundi or eyra-are rarely seen. When seen, they are usually shot on sight, but their very rarity makes them hunters' trophies, so that only seldom does the mammalogist obtain a specimen. Indeed, the paucity of published records would indlicate that only rarely does he hear of them. For this reason, it seems pertinent to bring some of the more recent records together, and to add a new one.
