s 94c (Pl. 25, fig. 13). There seems to be
an exception to the whole bird appearing as a head-dress exclusively
with women in Tro-Cortesianus 26c (Pl. 26, fig. 1), where god F appears
with a head-dress composed of the whole bird. The bird is also seen as a
head-dress on Altar Q from Copan (Pl. 26, fig. 3). The head of the macaw
appears as part of the head-dress of god H in Dresden 11a (Pl. 26, fig.
13), god E in Dresden 11b (Pl. 26, fig. 11), god F in Dresden 14b, god D
in Tro-Cortesianus 89a (Pl. 26, fig. 5) and of women in Dresden 12b (Pl.
26, fig. 6) and 19a (Pl. 26, fig. 9). In the rites of the four years in
Tro-Cortesianus 37b, there are two birds which are quite different from
those we have been considering, but which may represent macaws (Pl. 25,
fig. 12; Pl. 26, fig. 10).

In the Nuttall Codex, occur several figures of heavy-billed birds that
may be macaws or other smaller parrots of the genera _Amazona_ or
_Pachyrhynchus_. They are not, however, certainly identifiable (Pl. 26,
figs. 4, 7).

IMPERIAL WOODPECKER (_Campephilus imperialis_). We have here introduced
two drawings from the Nuttall Codex (Pl. 27, figs. 5, 6) which seem to
represent the Imperial ivory-billed woodpecker, a large species that
occurs in the forests of certain parts of Mexico. The figures show a
long-billed bird with acutely pointed tail feathers, a red crest, and
otherwise black and white plumage. The red crest of the woodpecker is of
course highly conventionalized in the drawings where it is shown as of a
number of erect feathers instead of the prominent occipital tuft of
this bird. The crest and particularly the pointed tail feathers and long
beak combined with the characteristic coloring seem to leave little
doubt as to the identity of the species figured. This bird does not seem
to appear in the Maya drawings.

RAVEN (_Corvus corax sinuatus_) (?). There occurs in the Nuttall Codex a
figure of a large black bird (Pl. 27, fig. 7), which may be a black
vulture, but which, from the presence of what appear as prominent
bristles over the nostril, may also be a raven. These bristles are
rather prominent in ravens and quite lacking in the vulture, so that we
are led to identify the drawing as representing the former bird. We have
found no other figures that suggest ravens.

MISCELLANEOUS BIRDS. Four drawings of birds from the Aubin manuscript are
shown here (Pl. 27, figs. 8-11), in order that the conventionalization of
the bird form may be
