TOzzEK] EXCAVATION AT SANTIAGO AHUITZOTLA, MEXICO 51 



elements in this type of design are ropes or fillets of clay. There is 

 much variety, however, in the designs of this class. Plate 17, a, shows 

 a simple form, a rope effect along the rim of the piece. Another form 

 is made by laying a ribbon of clay along the surface of the jar and 

 pressing it down at intervals with the finger (pi. 17, h). This form 

 may be combined with a molded design as in plate 17, c. A more 

 pleasing form is made by spiral pieces of clay laid above a line of 

 pellets. Plate 17, d, shows a design of this sort. This piece is very 

 heavy and is covered with red paint applied after the oUa was fired. 

 Plate 17, e, shows the same border combined with a modeled bird 

 form. 



Type IX, Emhossed. — The characteristic feature of this type is the 

 addition to the body of the piece of small pellets of clay covering at 

 equal intervals the whole or a portion of the outside of the olla (pL 17, 

 /) . The bosses may be combined w^ith incised lines (pi. 17, g) . A com- 

 mon iy\i& of Archaic potter}^ might come also into this class. There 

 is a heavy rim and at frequent intervals along the rim bosses or rib- 

 bons of clay are attached (Boas xVlbum, pis. 37, 9, 12, and pi. 55, 5, 6). 



Type A', Carved. — It has seemed best to place in a separate class 

 that type of pottery in which the decoration seems to have been made 

 in the wet clay of the piece itself b}^ means of a sharp instrument. 

 Plate 17, h, shows a shard of this type. The design is similar to that 

 of plate 17, 6, but the technique of the two is quite different. 



Type XI, Stick polished. — This is a type of black pottery usually 

 in the form of small globular vases which have a rough texture. 

 The simple design of straight lines is made by rubbing down parts 

 of this rough finish. The polished or smooth portions of the sur- 

 face form the design. 



Type XII, Painted, C oyotlatelco type. — There is a type of painted 

 pottery that is found at this site more frequently than in any other 

 hitherto excavated. It has, therefore, been called the " Coyotlatelco 

 type," as the center of its manufacture may have been here. It is 

 clearly Toltec, and most of the pieces here described came from Pits 

 XV and XVI and from the deposits in the wells. There is an Archaic 

 type that is superficially similar to this. The latter shows less polish, 

 however, and the design in red on the outside is more roughly done. 

 The Coyotlatelco type consists of a yellow slip with a rich red de- 

 sign. It has a good polish. The yellow varies, sometimes becoming 

 a cream. The shapes of the vessels also vary, the most common form 

 being the bowl with or without solid legs. The designs are found 

 either on the outside or on the inside. Rarely is the same piece 

 decorated on both sides. The design is usually composed of several 

 elements arranged in horizontal bands around the olla and separated 

 by solid red lines sometimes 1 cm. wide. A solid band almost in- 

 variably runs around the edge, usually on the inside. The elements
