posits from the Old Red " cornstone," upwards, was shown by them to be : 

 — 1. Laminated yellow sandstones, with pebble-beds and sands. 2. Bright- 

 yellow sandstones, containing PtericJitJiys. 3. Brecciated yellow sand- 

 stones, pebble-beds, sandy layers, and laminated sandstones. 4. Sandy 

 and concretionary limestone. 5. Grrey oolitic limestones, containing pala- 

 tal teeth of great size. 6. Clays, with ferruginous bands. 7. Shaly cri- 

 noidal limestones. 8. Clays with limestone concretions, and shaly lime- 

 stones. Against the last-mentioned bed the Millstone Grit rests uncon- 

 formably. These beds thicken out at Oreton, a mile east of this Farlow 

 section, and are there extensively worked for various economic purposes, 

 the oolitic limestones, locally termed " jumbles," being used for decorative 

 purposes under the name of Clee HiU Marble. In describing the physical 

 conditions of the localities, mention was made of the " Mole river," which, 

 losing itself at the west end of the ridge, takes a subterranean course 

 nearly parallel with its axis, and reappears at its lower end, a mile distant. 

 An interesting fact was communicated to the authors by the Eev. J. Wil- 

 liams, of Farlow, of an accidental accumulation in the hollow of its inlet of 

 a body of water estimated at 1,635,000 cubic feet, the whole of which was 

 carried away in forty-eight hours by the sudden clearance of the channel. 

 In describing the palaeontology of these rocks, the authors specially drew 

 attention to the fortunate discovery, in the yellow sand>itone of Farlow, of 

 PtepicJithys macrocejjhalus (spec, nov., Egerton), made while reducing the 

 thickness of a large ripple-marked slab sent them by Mr. Weaver Jones in 

 illustration of the physical conditions of the deposit. This Pterichthys pro- 

 ving identical with the fragment previously found in the Farlow Sandstone 

 by Thos. Baxter, Esq., F.G-.S., they attached to the paper a descriptive note 

 on that fossil, by Sir Philip Egerton, in which the Farlow PtericJitJiys was 

 contrasted with that of Dura Den, and additional proof given of the identity 

 of the genera Pamphractus and PtericJitkys. In addition to pterichthyoid 

 remains, scales of two species of Soloptychius, one probably new, had been 

 found by them. The richness of the overlying limestones in palatal teeth 

 was shown by a fine series of examples, amongst which Orodtis ramosus, of 

 unusual size and in perfect condition, and an undescribed Pcecilodus, of 

 great magnitude, were most conspicuous. Other genera represented were 

 Jielodus, Psammodus, Cladodus, Cuchliodus, Petalodus, and Ctenopty- 

 cliiiis. Ichthyodorulites, of large size and rich ornament, chiefly belong- 

 ing to the genera Cfenacanthus and OracantJms, accompany these teeth. 

 The notices of the invertebrate fauna given by the authors proved the as- 

 sumed lowness of the Oreton Limestones in the Mountain Limestone series 

 — the zone of PJiynconella pleurodon being well marked, crinoidal and 

 bryozoan remains abundant though fragmentary, and corals nearly absent. 

 A large series of PtericJitJiyes and of rock-specimens were exhibited in il- 

 lustration by Mr. George E. Hoberts ; and a collection of palatal teeth 

 was liberally sent for exhibition by W. Weaver Jones, Esq., of Cleobury 

 Mortimer, and by Edward Baugh, Esq., of Bewdley. 



2. " On some Fossil Plants, showing Structure, from the Lower Coal 

 Measures of Lancashire." By E. W. Binney, Esq., F.E.S., F.G.S. After 

 noticing the views taken of the structure of Lepidodendron by Hooker and 

 others, the author proceeded to describe three portions of calcified stems, 

 Lepidodendroid in external appearance, two of which exhibit in section a 

 central axis composed, not of cellular tissue, but of large, transversely 

 barred, hexagonal vessels. These two specimens the author refers to a new 

 species, Sigillaria vascularis. The third specimen differs from the others 

 in the absence of the thin radiating cylinder of barred vessels ai'ound the 

 central axis ; this he terms Lepidodendron vasculare. Microscopical pre- 

 parations and photographs of sections were supplied by the author.
