slabs containing SphenopTiyllum. They were referred by Mr. Scudder 

 to the Blattarice. 



From the Devonian beds of Gaspe the author stated that he had 

 obtained a small species of Cephalasjns, the first yet detected in 

 America. With it were spines of MacJiairacanihus and remains of 

 some other fishes. At Gaspe he had also obtained a new sjiecies of 

 Psilophyton, several trmiks of Prototaxites, and a species of Cyclo- 

 stigma. 



Discussion. — The President objected to the term Reptiles being applied to 

 Amphibia, from -which they were totally distinct. He questioned the safety of 

 attributing the jaw to Bapketes, of which no lower jaw had been previously found. 



Mr. Etheridge remarked that the Cephafaspis differed materially in its pro- 

 portions from any in either the Russian or British rocks. 



4. " Note on a Crocodilian Skull from Kimmeridge Bay, Dorset." 

 By J. W. Hulke, F.K.S., F.G.S. 



The author described a large Steneosaurian skull in the British 

 Museum, from Kimmeridge Bay, which had been previously re- 

 garded as Pliosaurian, and was recently identified with Dakosaurus 

 by Mr. Davies, Sen. From the agreement of their dimensions, and 

 their occurrence near together, the author thought it probable that 

 this skull and the lower jaw described by him last session belonged 

 to the same individual. It difi"ers from the Steneosaurus rostro-minor- 

 in the greater stoutness of its snout, in the presence of an anterior 

 pair of nasal bones prolonged into the nostril, and in the number of 

 its teeth. The author proposed to name it Steneosaurus Manseli, 

 after its discoverer. 



o. " Note on some Teeth associated with two fragments of a Jaw 

 from Kimmeridge Bay." By J. W. Hulke, F.E.S., F.G.S. 



The author described some small teeth, associated with fragments 

 of a long slender snout, not unlike that of an Ichthj^osaur, but too 

 incomplete to be certainly identified. The teeth are peculiar in the 

 great development of the cementum, which gives the base of the 

 tooth the form of a small bulb. The exserted crowns are slightly 

 curved, smooth, cylindrical, and pointed. The attachment to the 

 dentary bone was probably by means of the soft tissues, and the 

 teeth seem to have been seated in an open groove in the surface of 

 the jaw-bone. Until additional material reveals the true nature of 

 this fossil, the author proposes to place it alone, and to call it pro- 

 visionally Euthelciodon. 



IT. January 12th, 1870.— Prof Huxley, LL.D., F.E.S., President, 

 in the Chair. The following communications were read : — 1. " On 

 the Geological Position and Geographical Distribution of th6 

 Reptilian or Dolomitic Conglomerate of the Bristol Area." By E. 

 Etheridge, Esq., F.G.S., Pala3ontologist to the Geological Survey of 

 Great Britain. 



The author noticed the history of our knowledge of the Dolomitic 

 conglomerates of the Bristol area from which the remains of Dino- 

 saurian reptiles have been obtained, and then described their mode 

 of occurrence and distribution over the district near Bristol. He
