I will now pass over the many hundreds of pieces with designs too conventional to furnish a clew to the original animal forms, yet still suggesting their existence, to those in which the life forms can be traced with ease or in which they are delineated with a much nearer approach to nature. The manner of introducing life forms into the panels of the encircling zones is illustrated in the following figures. In the vase shown in Fig. 176 there are four panels, two short and two long, separated by vertical bands. The short panels are black, but the long ones are occupied by rudely drawn figures of alligators, some of which are very curiously abbreviated. At the right hand in the cut we have simply the head with its strong recurved jaws and notched crest. The principal figure at the left is a two headed alligator, the body being straight and supplied with two feet. The ground finish of the decorated band is in the light gray tint and the alligator figures and vertical septa now appear in that color. The ground of the remainder of the surface is red. It will be seen that in this case the panel outlines are rather elaborate and that the neck and base are striped in a way to enhance considerably the beauty of the vessel. Additional examples of animal devices are given in Figs. 177 and 178. The significance of the curious figure seen in the first is not easily determined, although we do not hesitate to assign to it an animal origin. There is a suggestion of two sitting figures placed back to back between the upright serrate lines. In the second piece, which is from another vessel, the space between the serrate lines is occupied by a sketchy figure which, in the phraseology of heraldry, may be likened to a monkey rampant. [Illustration: Fig. 179_a_. Design from vase shown in Fig. 179.] [Illustration: Fig. 180. Vase decorated with highly conventional life forms--½.] In Figs. 179 and 180 I present very interesting examples in which the arched panels are used. In the first the compartments are occupied by a favorite Chiriquian motive, which consists of groups of lines curled up at one end like unfolding fronds. The whole group represents a very highly conventionalized animal figure (Fig. 179_a_). The devices occupying the upright panels take the place of the animal heads shown in several preceding figures. In the arched panels shown in Fig. 180 we have the frond-like motive treated in a manner to make it pretty certain that a reptilian form is intended. These figures are fully and systematically presented in a succeeding section.
