across the widest part of the valley, and were embedded in the gravel, six 
feet below the surface. The}' belong to the genus JEquus. The flint was 
picked out from amongst the materials thrown out of the trench.

the Devonian Plants of Maine, Gaspe, and New York." By J. W. 
Dawson, LL.D., F.E.S., F.G.S. 
Since the preparation of his paper on the Devonian Flora of North- 
Eastern America, published in the Society's Journal, vol. xviii. pp. 296 
et seq., the author has been enabled to explore more thorouglil}'- than be- 
fore the plant-bearing beds of Perry, in Maine, Gaspe, and New York. The 
results of these further explorations, together with descriptions of the new 
species of plants discovered, were given in this paper ; as also were some 
new and important facts respecting the distribution of the Devonian rocks 
of the State of New York, which give to several of the plants from that 
region a somewhat older geological position than that heretofore assigned 
to them. 
2. " Notice of a Ncav Species of Dendrerpeton , and of the Dermal Cover- 
ings of certain Carboniferous Eeptiles." By J. W. Dawson, LL.D., F.E.S. 
This paper referred to new facts ascertained in the course of a re-exarai- 
nation of the remains of reptiles from the Coal-formation of Nova Scotia, 
and first to the characters of a new and smaller species of Dendrerpeton, 
for which Dr. Dawson proposed the name of D. Oweni. The author then 
described the remains of skin and horny scales which he had lately dis- 
covered, and which he supposed to belong to Dendrerpeton Otceni, Hylo- 
nomus Wymani, and H. Lyelli. He also gave restorations of these ani- 
mals, according to what he regarded as the more probable arrangement of 
the parts ; and, after expressing his belief that Ilylonomns may have 
Lacertian affinities, he stated that should they prove to be really Batra- 
chian, a new Order must be created for their reception, many of the 
characters of which would coincide with those of the humbler tribes of 
lizards. 
3. " On the Upper Old Eed Sandstone and the Upper Devonian Eocks." 
By J. W. Salter, Esq., F.G.S. , A.L.S. 
The conclusions arrived at by Mr. Salter were based upon certain sec- 
tions in Pembrokeshire, Devonshire, and the North and South of Ireland, 
which he described in full, and compared Avith one another as well as with 
the Upper Devonian of the Continent and America, giving lists of fossils 
from the English localities. The sections in Devonshire and South Ire- 
land were contrasted wdth those in Pembrokeshire and North Ireland ; 
and it was shown that, although the physical features in the two cases 
very nearl}^ correspond, the Marwood series is constant, and the Pilton 
group of the former districts is a series unknovi n in Pembrokeshire, or 
only represented by beds, a few feet thick, at the base of the Carboniferous 
slate. The author endeavoured further to prove the intercalation of 
marine beds in the Upper Old Eed Sandstone, and, by the fossils, the cor- 
relation of the Marwood group of Devonshire with the uppermost part of 
that series. He stated his belief in Sir E. I. Murchison's suggestion, that 
the Caithness Flags belong to the Middle, and the Cephalaspis Beds of 
Scotland to the Lower Old Eed, which divisions he considered equivalent 
to the Middle and Lower Devonian respectively ; and concluded by assign- 
ing the Tilestones (or Ledbury shales) to the Lowest Devonian.

character of some of the Flint Implements found there." By J. Prest-
