Abstract

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.
