COYOTE (_Canis_). Two figures from the Nuttall Codex have been included as possibly representing coyotes (Pl. 35, figs. 1, 2). They are chiefly characterized by their prominent ears and bristling hair, and seem to be engaged in active combat. Coyotes of several species occur in Mexico and though not generally regarded as aggressive animals are of a predacious nature. No drawings of the coyote have been noted in the Maya codices. DOG (_Canis_). The dog (Maya, _peq_) evidently played an important part in the life of the Mayas as it does with other races of men generally. On Pls. 36, 37, we have included certain figures of dogs from several manuscripts. These may represent two breeds, for it is well known that both a hairy and a hairless variety were found by the early discoverers in Mexico.[359-*] Hairiness is more or less clearly indicated in the following figures:--Pl. 36, figs. 1-7, 12; Pl. 37, figs. 4, 5. The figures of dogs usually agree in having a black mark about the eyes that frequently is produced as a downward curved tongue from the posterior canthus. Sometimes, as in Pl. 37, figs. 1-3, 10, this tongue is not blackened. Commonly also black patches are elsewhere distributed on the body, generally on the back. These markings are probably the patches of color separated by white areas that occur frequently in dogs or other animals after long domestication.[359-†] We have included among the figures of dogs two in which the eye is differently represented and which are unspotted (Pl. 37, figs. 4, 6). These modifications may have some special significance, but otherwise the animals appear most closely to represent dogs. We have already suggested that the animal attired in man's clothing, and walking erect in Dresden 25a-28a is likewise a dog, though Stempell believes it to represent the opossum in support of which he calls attention to its prominent vibrissae and slightly curled tail.
