of the design are mainly geometrical with a number of curvilinear 

 figures. Life forms are seldom represented. There is a decided 

 difference between the designs on the outside and those on the inside 

 of the pieces. These will be considered under two classes. 



a. Interior designs : These are usually better drawn than those on 

 the exterior, with a greater definiteness of outline and a greater use 

 of the continuous band. The most common design is an undulating 

 curve running continuously around the piece (pi. 18, a, h). This 

 serpentine line may appear running vertically across a decorated 

 band (pi. 18, c). A variation is seen in the S or Z shaped figures 

 distributed along a zone (pi. 18, c) or arranged in definite lines 

 around the piece (pi. 18, d). Still another allied type is composed 

 of interlocking C's (pi. 18, e). This passes into the scroll (pi. 18, /). 

 A variation of the scroll is seen in plate 18, g-i. Another very com- 

 mon design on the outside of the ollas is a stepped figure in solid red 

 bordered by a single narrow stepped line (pi. 18, d~f, and Boas 

 Album, pi. 57, 9). Other common designs are as follows : A triangle 

 in solid red bordered by a single line with the apex of the triangle 

 to the right or left of its base (pi. 18, k, and Boas Album, pi. 57, 6), 

 a series of triangles or semicircles forming a band around the piece 

 (pi. 18, Z>, 7n), a checkerboard design as a decoration in the bottom 

 of the bowl (pi. 18, ^) , and a design difficult to describe (pi. 18, ]) . 



b. Exterior designs: There is a greater variety in the colors used 

 on the exterior of the pieces than those used on interior designs. 

 The yellow slip may be overlaid by a creamy white, especially on 

 the decorated border, and bands running down the sides at right 

 angles to the border. The undecorated portion usually has the regu- 

 lar yellow color. As already pointed out, there is a decided difference 

 in the character of the designs on those pieces decorated on the inside 

 and the pieces decorated on the outside. When the exterior has any 

 decoration it usually covers the greater part of the surface. There 

 are two fairly well defined types of exterior decoration. The first 

 shows many similarities in arrangement to that on the interior. 

 When the banded designs running around the piece are found they 

 are usually combined with broad stripes of red alternating with finer 

 lines running down the side (pi. 19, h). The most common exterior 

 designs of this type are as follows: The double line cross (pi. 19, 

 a, h), the crescent (pi. 19, a), the single volute (pi. 19, «, c), a contin- 

 uous line of volutes (pi. 19, d), and the S curve (pi. 19, c, e). A 

 design clearly representing the human footprint, as shown in the 

 manuscripts, is found on two pieces (pi. 19, /, g). The stepped 

 pyramid combined with the sCroll is seen in plate 19, h. 



The second type of exterior design is bolder and less well drawn 

 than the first, described above. The lines are thicker and often of 

 a darker red. There may be large or small circles of solid red (pi.
