The glyphs associated with the dog are interesting as we have, as in the case with the deer, one showing a realistic drawing of a dog's head in Tro-Cortesianus 91d (Pl. 37, fig. 13) and several others far more difficult of interpretation. Pl. 37, fig. 11, seems to stand for the dog as it is found in several places where the dog appears below, Dresden 21b, 40b. It is thought by some to represent the ribs of a dog which appear in somewhat similar fashion in Pl. 37, fig. 8. Some of the glyphs in the codices for the month _Kankin_ show the same element (text figs. 8-10). [Illustration: Figs. 8, 9, 10. GLYPHS FOR MAYA MONTH KANKIN (RIBS OF DOG).] The Nahua day sign _Itzcuintli_ signifies dog and corresponds to the Maya Oc (Pl. 36, figs. 9-11). This in turn is considered by many to stand for the dog as the animal of death and signifies the end. The sore, cropped ears of the domesticated dog are supposed to be represented in this sign, Oc. Nahua and other day signs for _Itzcuintli_ (dog) are shown in Pl. 36, figs. 4, 6, 13. BEAR (_Ursus machetes_; _U. horriaeus_). In northern Mexico, in Chihuahua and Sonora, occur a black bear (_Ursus machetes_) and the Sonoran grizzly (_U. horriaeus_). It is unlikely that the Mayas had much acquaintance with these animals since they range more to the northward than the area of Maya occupation. Stempell has identified as a bear, a figure in Dresden 37a (Pl. 35, fig. 3). This represents a creature with the body of a man walking erect but with the head apparently of some carnivorous mammal, as shown by the prominent canine tooth. This appears as a _tonalamatl_ figure. The resemblance to a bear is not very clear. Less doubt attaches to the figure shown in Pl. 35, fig. 4, which seems almost certainly to depict a bear. The stout body, absence of a tail, the plantigrade hind feet, and stout claws, all seem to proclaim it a bear of one of the two species above mentioned. This picture is found in connection with one of the warriors shown in the bas-relief of the Lower Chamber of the Temple of the Tigers at Chichen Itza. It seems clearly to designate the figure in much the same way as figures are named in the Mexican writings, _i.e._, by having a glyph showing this nearby. Attention has already been called to the fact that here at Chichen Itza, and, especially on this bas-relief, there is much which shows a strong influence from the north. The two figures in Tro-Cortesianus 43a are probably bears. Förstemann (1902, p. 68) considers that they are men masked as _Chacs_ or _Bacabs_.
