(1) The clay is quite fine, of white colour, with a slightly
grayish-yellow tinge. The decorations are black and red, or black
only. This is the predominant type, and may be seen in Plates I. and
II.; also Plate III., _a_.

(2) Of a very similar character, but somewhat coarser in texture, and
heavier. See Plate III., _b_ to _g_, and Plate IV., _f_ Both these
groups include variations in the decorative designs, as may be seen
in the rest of Plate IV.

(3) Brown pottery with black decorations. See Plate V., _a, b, c_,
and _e_.

(4) Black ware.

Here follows a condensed description of the more important specimens

PLATE I

Heights: _a_, 18.5 cm; _b_, 15.2 cm; _c_, 16.2 cm; _d_, 18.8 cm; _e_,
11.3 cm; _f_, 8.5 cm.

_a_, particularly graceful in outline and decoration, is a
