During recent years considerable attention has been devoted to the study of certain structures in stratified rocks which have been attributed to sliding or slumping of sediment during deposition. The object of this paper is to place on record an interesting example of such a structure which has apparently resulted from contemporaneous movement while the material was accumulating. The structural features in question are displayed in the greywackes of the Gala Group (Tarannon) and occur on the west side of the road at a point close to the Cow Peel bridge, across the Newhall Burn, 2½ miles south of Innerleithen (One-inch Geological Map, Sheet 24). Here, the road has within recent years been widened and the greywackes and shales have been cut into a cliff-like face. The beds dip at an angle of approximately 70° to the south-east and it is on the dip slopes that these structural features are displayed. There are at least two different types of structure exposed in the section and the more striking of the two is shown conspicuously on Plate II. This particular structure is well developed on the surface of one of the beds of greywacke and, as can be seen from the photograph, the examples form a pattern which rudely resembles gigantic scales, especially where clustered together. They are U- or tongue-shaped and range in size from 2 to 9 inches in breadth. Nearly all terminate in a swollen rounded edge, the steep front of approximately an inch, in the largest bulbs,
