Fig. 346—Triangular pattern with feathers
In the specimens represented in [figures 347] and [348] marginal dentations are used. I have called the design referred to an S-form, which, however, owing to its elongation is somewhat masked. The oblique bar in the middle of the figure represents the body of the letter, the two extremities taking the forms of triangles.
