Maya day _Kan_. Pl. 12, figs. 10, 12, 14, show
representations of the day corresponding to _Cuetzpalin_ in the Aubin
and Nuttall codices. These show a stout spineless species with a short
thick tail and may be the Gila monster (_Heloderma horridum_), a large
and somewhat poisonous species having much these proportions.

Further offerings are shown in Pl. 12, figs. 7, 8. These seem to be the
heads and forefeet of lizards, but, from the shape of the head, perhaps
not of iguanas.

In Stela D of Copan, the _Uinal_ period glyph seems to be represented by
a spineless lizard covered with scales (Pl. 12, fig. 9). Frog-like
characteristics also appear. This stone monument is remarkable from the
fact that the glyphs are all more or less realistic representations of
human and animal forms. It should be noted that there certainly seems to
be some connection between the _Uinal_ period glyph and the lizard. Pl.
13, fig. 9, represents a _Uinal_ glyph from the Temple of the Foliated
Cross at Palenque and the lizard form is clearly seen in the eyebrow and
the upper jaw. Compare also Pl. 13, fig. 11, and Pl. 28, fig. 3. A
collection of glyphs of this period shows clearly the lizard-like
character of the face.

That some connection existed between the lizard and the idea of rain
seems clear from a reference in the _Relacion de la Ciudad de Merida_
(1900, p. 51).[319-*] Finally the lizard is shown in Dresden 3a (Pl. 12,
fig. 11) directly in front of god H beside the scene of human sacrifice.

CROCODILE. The text figure (1) shows a dorsal view of a crocodile (Maya,
_ayin_) carved on the top of Altar T at Copan. The general form is
considerably conventionalized with limbs elongated and provided with
human hands and long toes. The protuberances of the back are roughly
shown by oval markings, which are here continued on the legs. The large
scales of the ventral surfaces also appear at the sides of the body, and
along the posterior edges of the limbs. The tail is shortened and
bifurcate. The most interesting portion, however, is the head. The snout
is distinctly pinched in at the base, though broadened again distally.
In the alligator the snout is broad and tapers but little. As in other
representations of the crocodile, the lower jaw does not appear, and
even in this dorsal view the artist seems to have deemed it necessary to
show the row of teeth as if in side view, or as though they projected
laterally from the mouth. What may represent
