The recent gift to the Museum of a fine series of Lower Palæozoic fossils from the Haverfordwest area by Mr. V. M. Turnbull, M.A., who has personally collected them with much care, has at length provided us with the means of determining many of the interesting species which were mentioned without specific names (on account of their imperfect preservation) by Messrs. Marr and Roberts in their paper on this district. The collections from which their lists were drawn up are in the Sedgwick Museum.
