[Illustration: FIG. 64.—The Great Anteater (_Myrmecophaga jubata_). (From Sclater, _List of Animals in Zoological Society’s Gardens_, 1883, p. 190.)] _Tamandua._[101]—This genus closely resembles the last in anatomical structure, but the head is much less elongated, the fur is short and bristly, the tail tapering, prehensile, with the under side throughout and the whole of the terminal portion naked and scaly. The stomach is similar to that of _Myrmecophaga_, but with the muscular pyloric gizzard not quite so strongly developed. There is a distinct ileo-colic valve and a short globular cæcum. The fore foot has a very large claw on the third toe, moderate-sized claws on the second and fourth, a very minute one on the first, and none on the fifth, which is entirely concealed within the skin. The hind foot has five subequal claws. Vertebræ: C 7, D 17, L 2, S 5, C 37. There are very rudimentary clavicles. [Illustration: FIG. 65.—Tamandua Anteater (_Tamandua tetradactyla_). From _Proc. Zool. Soc._ 1871, pl. xliii.] The Tamandua (Fig. 65) is much smaller than the Great Anteater, and differs essentially from it in its habits, being mainly arboreal. It is an inhabitant of the dense primeval forests of South and Central America. As different individuals vary much in their coloration, it is possible that there may be more than one species. The usual colour is yellowish-white, with a broad black lateral band, covering nearly the whole of the side of the body.
