Nucula, a small Aviculo-pecten, and Spirifer. A large Aviculo- 
pecten probably from the same locality also occurs; and one 
weathered block of white limestone, perhaps from Bell Sound, yields 
Spirifer alatus, a small Productus like the P. horridus figured by 
De Koninck as brought from Spitzbergen by M. Robert, and a large 
foliaceous Stenopora. These last, with a specimen of Spirifer 
cristatus, on another loose block, are the only forms having a 
Permian aspect in the collection made by Mr. Lamont. 
2. **On the so-called Wealden Beds at Linksfield, and the 
Reptiliferous Sandstones of Elgin.”” By C. Moore, Esq., F.G.S. 
When visiting the section at Linksfield, near Elgin, in the 
autumn of 1859, the author recognized a similarity of appearance 
between the shales and thin limestone-bands at Linksfield and those 
of the Bone-bed series (at the base of the Lias) at Pylle Hill, near 
Bristol, at Aust Passage and at Penarth, on the Severn, and at the 
Uphill cutting on the Great Western Railway. Giving in detail 
the sections at Pylle Hill and at Linksfield, the author pointed out 
some close lithological resemblances, and stated that he recognized 
the ‘‘ white lias,” the ‘“‘ Cotham marble,” the ‘‘ bone-bed,” and the 
gypseous clay-bands of the south in the quarry at Linksfield. 
Cyprides, Estherie, remains of Hybodus, Lepidotus, Acrodus, and 
Plesiosaurus, Mytilus, Modiola, Unio, and Cyclas, from the Links- 
field beds, were among the paleontological evidences which the 
author brought forward as supporting his correlation of the beds in 
question. 
He next offered some observations on the red layer of clay, sand, 
and stones intercalated between the Linksfield shales and the corn- 
stone, and, not accepting Capt. Brickenden’s opinion of its having 
been thrust in by the action of ice against the escarpment during 
the formation of the boulder-clay, he suggested that an early glacial 
period, contemporaneous with the Lower Lias, destroyed some of 
the lower shales and limestone of Linksfield, leaving their remnants 
imbedded in a red drift to be covered by the succeeding undis- 
turbed deposits of the bone-bed series. 
Mr. C. Moore next remarked that the Cornstone at Linksfield, 
on which all the above-mentioned beds rest, might possibly be of 
Triassic date, as he had observed on the flanks of the Mendips and 
elsewhere a stone of a similar aspect, belonging to the Trias, and 
occasionally yielding remains of Reptiles and Fishes ; to this rock the 
author refers the druidical stones of Stanton Drew. Some observa- 
tions on the discovery of reptilian and mammalian teeth in a Triassic 
deposit near Frome, by the author, on the possible relations of 
some of these to the Reptilia found in the Lossiemouth sandstone, 
and on the probable Secondary age of the latter, concluded the paper.
