In looking over a large series of the vases it will be seen that the tendency of decoration is toward the zonal arrangement, the spaces being narrow and long, even when divided into the usual number of panels. As a consequence the motives tend to take linear forms. Parts are repeated or greatly drawn out to fill the spaces. This phase of conventional evolution may be illustrated by a multitude of examples.
[Illustration: _a, b, c, d, e, f_ Fig. 274. Series of forms showing modification through use in narrow zones.]
Beginning with an ordinary form in Fig. 274, _a_, we advance under the restraint of parallel border lines through the series, ending in a simple meander, _f_, the spaces about which are, however, filled out with the conventional scale symbols, the triangles inclosing dots. Thus we witness the transformation of the life form into a linear device, in which the flexures of the body are emphasized and multiplied without reference to nature, and there is little doubt that the series continues further, ending with simple curved lines and even with straight lines unaccompanied by auxiliary devices.

Next to the body line the most important of the alligator derivatives is the notched or dotted hook, which in the lost color group stands sometimes for the whole creature, but more frequently for one or more of the members of its body, the snout, the tail, or the feet. It is employed singly or in various arrangements suited to the shape of the spaces to be filled or occurs in connection with the body line or stem, where, by systematic repetition, it serves to fill the triangular interspaces. Take, for example, an ornament (Fig. 275) which encircles the shoulder of a handsome vase of the lost color group. The space is neatly filled with groupings in which the simple life coil elements are joined one to another in such a way as to give somewhat the effect of an ordinary running ornament. The same motive takes a different form in Fig. 276, which is part of the decorated zone of an earthen drum (see Fig. 235). Here the body of the creature is represented by a wide meandered line, and to this the notched or scalloped hooks are attached with perfect regularity, one to each angle of the meandered body. In other examples the angular geometric character extends to every part of the detail and the curved hooks lose their last suggestion of nature and are entirely dropped or used separately.
