The animal shown to be a rabbit in Dresden 61 (Pl. 30, fig. 8) is pictured seated on the open jaws of a serpent in the same way as the peccary on the following page. These two animals, together with two representations of god B and the black god (Dresden 61), are each clearly connected with the serpents on which they are sitting. The Nahua day _Tochtli_ signifies rabbit and naturally the animal occurs throughout the Mexican manuscripts as representing this day (Pl. 30, figs. 3, 4). OTHER RODENTS. We have included in Pl. 29, figs. 5, 7, 8, three undetermined mammals. The second of these is characterized by the two prominent gnawing teeth of a rodent and by its long tail. It may represent a pack rat (_Neotoma_) of which many species are described from Mexico. In its rounded ears and long tail, fig. 5 somewhat resembles fig. 7, but it lacks the gnawing incisors. Still less satisfactory is fig. 8 from Tro-Cortesianus 24d, at whose identity it seems unsafe to hazard a guess. It is shown as eating the corn being sowed by god D. JAGUAR (_Felis hernandezi_; _F. h. goldmani_). Throughout its range, the jaguar (Maya, _balam_ or _tšakmul_) is the most dreaded of the carnivorous mammals. It is, therefore, natural that the Mayas held it in great awe and used it as a symbol of strength and courage. A few characteristic figures are shown in Pl. 34, figs. 1-3; Pl. 35, figs. 5-14. The species represented is probably _Felis hernandezi_, the Mexican race of jaguar, or one or the other of the more or less nominal varieties named from Central America. The distinguishing mark of the jaguar, in addition to the general form with the long tail, short ears and claws, is the presence of the rosette-like spots. These are variously conventionalized as solid black markings, as small circles, or as a central spot ringed by a circle of dots (Pl. 35, fig. 12). Frequently the solid black spots are used, either in a line down the back and tail or scattered over the body. The tip of the tail is characteristically black, and the teeth are often prominent. Such a figure as this (Pl. 35, fig. 10) Stempell considers to be a water opossum (_Chironectes_), for the reason that it is held by the goddess from whose breast water is flowing. This can hardly be, however, for not only are the markings unlike those of the water opossum, but the large canine tooth indicates a large carnivore. Moreover, the water opossum is a small animal, hardly as big as a rat, of shy and retiring habits, and so is unlikely to figure in the drawings of the Mayas.
