There is a close resemblanoe between the fossil contents of the “Upper Ludlow Tilestones,” as described by Mr. Roberts, of Kidderminster, in the last number of The Geologist, and those of certain strata developed in this neighbourhood. The rocks of the southern districts of Forfarshire have been described by Fleming and Miller, and their fossils have attracted the attention of the scientific world. I am acquainted with sections in the north-eastern division, an account of which has not yet appeared in print, and it may be of interest to indicate their organisms.
