identity of the genera Pamphractus and Pterichthys. In addition to 

 Pterichthyoid remains, scales of two species of Holoplychius, 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 Orodus ramosus, of 

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

 of great magnitude, were most conspicuous. Other genera repre- 

 sented were Helodus, Psammodus, Cladodus, Cochliodus, Petalodus, 

 and Clenoptychius. Ichthyodorulites, of large size and rich orna- 

 ment, chiefly belonging to the genera Ctenacanthus and Oracanthus, 

 accompany these teeth. 



The notices of the invertebrate fauna given by the authors proved 

 the assumed lowness of the Oreton limestones in the Mountain- 

 limestone series, — the zone of Rhynchonella pleurodon being well- 

 marked, Crinoidal and Bryozoan remains abundant though fragmen- 

 tary, and Corals nearly absent. 



A large series of Pterichthyes and of rock-specimens were ex- 

 hibited in illustration by Mr. George E. Roberts ; 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.R.S., 

 F.G.S. 



After noticing the views taken of the structure of Lepidodendron 

 by Hooker and others, the author proceeded to describe three por- 

 tions of calcined stems, Lepidodendroidin 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 vascu- 

 laris. The third specimen differs from the others in the absence of 

 the thin radiating cylinder of barred vessels around the central axis ; 

 this he terms Lepidodendron vasculare. 



Microscopical preparations and photographs of sections were sup- 

 plied by the author. 



3. ■' Supplemental Notes on the Plant-beds of Central India." By 

 the Rev. S. Hislop. In a Letter to the Assistant-Secretary. 



Mr. Hislop, in noticing the discovery of more remains of Plants, 

 Insects, and Fishes at Kota on the Pranhita, stated that he certainly 

 now thought that the ichthyolitic beds of Kota (probably Lower 

 Jurassic in age) are higher in relative position than theplant-sandstone 

 of Nagpur, which, with the Sironcha sandstone underlying the Kota 

 limestone, belong to the Damuda Group. He remarked also that, 

 in his opinion, the Tce?iiopteris of Kampti would prove that the Da- 

 muda and Rajmahal groups cannot be widely separated.
