the two sides exactly corresponding. Each
side consists of a simple key pattern with the shank inclined to the
rim of the bowl and a bird emblem at its junction with the other
member.

In figure 320 there is a greater development of this pattern by an
elaboration of the key, which is continued in a line resembling a
square spiral. There are also dentations on a section of the edge of
the lines.

LINEAR FIGURES ON FOOD BOWLS FROM SIKYATKI]

In figure 321 there is a still further development of the same design
and a lack of symmetry on the two sides. The square spirals are
replaced on the left by three stepped figures, and white spaces with
parallel lines are introduced in the arms of a W-shape figure.

[Illustration: FIG. 323--W-pattern; bird form]

In figure 322 the same design is again somewhat changed by
modification of the spirals into three triangles rimmed on one side
with a row of dots, which are also found on the outer lines
surrounding the lower part of the design.

[Illustration: FIG. 324--W-pattern; median triangle]

In figure 323 the same W shape design is preserved, but the space in
the lower reentrant angle is occupied by a symmetrical figure
resembling two tail-feathers and the extremity of the body of a bird.
When this figure is compared with the design on plate CXLVI, _a_,
resemblances are found in the two lateral appendages or wings. The
star emblem is also present in the design. The median figure in that
design which I have compared to the tail of a bird is replaced in
figure 324 by a triangular ornament. The two wings are not
symmetrical, but no new decorative element is introduced. It, however,
will be noticed that there is a want of symmetry on the two sides of a
vertical line in the figure last mentioned. The right-hand upper side
is continued into five pointed projections, which fail on the
left-hand side. There is likewise a difference in the arrangement of
the terraced figures in the two parts. The sides of the median
triangles are formed of alternating black and white blocks, and the
quadrate figure which it incloses is etched with a diagonal and cross.

The decoration in figure 325 consists of two triangles side by side,
each having marginal serrations, and a median square k
