Certain beds of the well-known grey shales have recently been exposed at Lord's Hill, New Town, by Mr. Dorman, builder, who kindly afforded me every facility for their examination. These beds are intimately associated with the beds containing the coal seams at New Town, and as they were unusually full of impressions of plant remains, I spent several days in making collections and in thoroughly examining the numerous forms. The results have far surpassed my utmost expectation, for in the following pages I shall be able to show that about 15 forms of great interest, new to science, have been added to the list of the Mesozoic plants of this island. The cycadeous and coniferous plants especially are very important, and are more fully discussed under the section where they are specifically classed and described. The following is a more complete list of the species observed by me at this place, all of which were obtained within the space of a few yards in width and one or two feet in depth. Shales of a similar kind, rich in plant impressions, and containing many forms in common, are frequently met with in road cuttings, etc., throughout the districts of New Town, G-lenorchy, Old Beach, Richmond, Spring Hill, and Spring Bay. It will he seen that the new discovery has contributed a very important addition to the already known plants of the period.
