figure, also, but both are present in the latter. The insect-like head
is made on much the same plan as that of the bee (Pl. 2, fig. 11), the
facial portion divided by a median line into a right and a left half
with a small triangle below for a mouth. The eyes, however, instead of
being circular like those of the bee are made as narrow elongated
projections extending inward from the dorsal margin of the facial disc.

The glyphs for god D in Dresden 7b (Pl. 3, fig. 11), Dresden 7c, and
Dresden 14b (Pl. 3, fig. 12) undoubtedly show three forms of the sign
for god D, only one of which (fig. 12) is given by Schellhas (1904, p.
22) among the signs of this god. In each of these cases the centipede
head surrounded by dots is shown in connection with the main part of the
glyph. In Dresden 44b (Pl. 3, fig. 13) there is a glyph which seems to
show the same centipede head although it has no connection with god D in
the place where it is found. In Dresden 27 (Pl. 3, fig. 14), moreover,
still another variant of the glyph for god D seems to occur. This shows
a prefix clearly representing the centipede and the "moon sign" is the
main part of the glyph. Directly beside this in the codex is found the
_Ahau_-like sign for god D and god D himself is represented in the
middle section of the page.

The association of god D with the centipede may be explained by the fact
that as this god is regarded as the Moon or Night god, so the centipede
is an animal which frequents dark places. Another point in this
connection may be made if we consider the head of the centipede in the
head-dress and in the glyphs as representing the day sign _Akbal_ (Pl.
3, fig. 10) as _Akbal_ in Maya means night. It must be admitted,
however, that the head might represent the day sign _Chuen_ almost as
well as _Akbal_. The centipede is connected with death and destruction
in the same way as the owl. Both are shown in Vaticanus 3773, 13,
associated with the "house of drought."

CRUSTACEA

With one possible exception no crustaceans were found depicted in the
Maya codices, but we have introduced figures of two from the Nuttall
Codex. The first of these (Pl. 4, fig. 5) is probably a crayfish,
perhaps _Cambarus montezumae_. It seems unlikely that the so-called
Spanish lobster (_Palinurus_) can be intended or the powerful spined
antennae would have been shown. It is interesting to note that the
stalked eyes are clearly pictured. The second example seems to be a crab
