IN ANCIENT AMERICAN ART. 167 



are all prominent, realistic features, and the dorsal fin is 

 conspicuous hj its size and position forward of the eyes. 



In figures 2 and 3, the several parts of the head, while 

 rudely done, are expressive, and the dorsal fin placed be- 

 tvveen the eyes in both is a prominent feature. In figure 

 3, the teeth are represented by bands passing from jaw 

 to jaw. 



In figure 4 these bands become small rounded masses, 

 while a larger one in the centre represents the dorsal fin, 

 as it holds the same positiou as a striated knob in the follow- 

 ing figure. 



In figure 5 the mouth and teeth are represented by cut 

 lines, and the ventral, as well as the pectoral fins, are shown 

 somewhat as in fig. 3 of the preceding plate. 



In figure 6 the pectoral fins are more closely united to 

 the mouth than in the last, and the dorsal fin is a small 

 striated cone in the centre of the raised lines forming the 

 mouth. 



The next step is shown in figure 7, where the pecto- 

 ral and dorsal fins are represented by three small cones, 

 between which are incised lines for the mouth and teeth. 



In figure 8 a deep notch is cut on the upper part of 

 the foot, defining the mouth of the fish under the raised 

 knob representing the dorsal fin, on each side of which are 

 two slight knobs for pectoral fins. 



In figure 9 all the parts have been eliminated except 

 the dorsal fin, or the round striated knob above the open- 

 ing in the foot. On one of the feet of the same tripod the 

 incised lines on the knob are omitted, and in this we find 

 the conventionalized fish reduced to its simplest form, — 

 which may be represented by my period.
