Diagnosis.—Segments bear eacli one or two rows of papilla, of uliicli not more than twenty are visible on one side of the compressed fossil. Spaces between papillse not less than the diameter o£ a papilla. Height of a segment about 0*25 mm. Width of specimen about 3 mm. Ratio of segment-height to width 8/100. Holotype.—A specimen collected by Dr. H. L. , and presented by him to the British Museum : Geol. Dept. A. 1946. Horizon.—Lower Ludlow, just above the Starfish bed. Locality.—Martin's Shell, below Mocktree, near Leint- wardine, Herefordshire. This specimen (fig. 1) presents many features of interest other than those due to its remoteness in time and space from the species previously described. It is preserved in counter- part as two imprints, but some of the substance of the integu- ment remains here and there as round calcified knobs, appa- rently where the wall was thickened by papillae. The chemical composition of these knobs is unknown, and may be due to petrifaction of a chitinoid substance. Proto scolex latus. The specimen lies in a curve shaped like the head of a 2. Its outline is not very clear-cut as seeii under a lens. The diameter is about 3 mm. in the upper part of the ascending stem of the 2; towards the end of the curve it lessens gradually to 2'3 mm., then suddenly tapers or rounds off like the end of an earthworm. Towards the lower end of the stem of the 2 the width gradually lessens to 2 mm., and then the fossil seems to fade away into the matrix, both outline.
