Bradstock), and~ as they are not far apart they would in time meet 

 and form a continuous channel (the Fleet), which would be widened 

 and kept clear by land- waters, aided pe.haps by tidal action as 

 suggested by Mr. Evans.* 



2. Mr. Bay Lankester records the discovery of Machairodus in 

 the Forest-bed of Norfolk ; and from the researches of Mr. Pengelly, 

 no doubt can remain that the great sabre-toothed tiger should be 

 retained on our list of British Fossil Mammals. 



3. Professor Owen describes two new Ichthyodorulites, Lepra- 

 canthus Colei from the coal-shale of North Wales, and Hybodus 

 complanaius (of Neoconiian age) from the Iguanodon quarry of 

 Mr. Bensted, at Maidstone. 



4. The Rev. T. Gr. Bonney discusses the origin of some sup- 

 posed " Pholas-burrows " in the Orinesheads. He is inclined to 

 attribute these holes (with Dr. Buckland and M. Bouchard-Chan- 

 tereaux) to the agency of land-snails, probably Helix aspersa ; but 

 we expect that many will still think it safer to regard them as due 

 to atmospheric influences, and that subsequently snails have taken 

 up their abodes in the hollows. 



5. Mr. C. E. De Piance writes on the Sm*face-Geology of the 

 Lake District. 



6. Dr. H. A. Nicholson describes some plant-remains from the 

 Skiddaw slates, and Mr. Henry Hicks some still older from the 

 Arenig beds of St. David's. 



7. Dr. Piuskin continues his researches on Banded and Brecciated 

 Concretions. 



8. Mr. Scrope combats some of Mr. Mackintosh's statements of 

 the marine origin of certain terraces, popularly called " Lynchets ' : 

 or " Balks." These he regards as of artificial origin, to be owing to 

 the disturbing action of the plough and the mattock on the surface- 

 slopes, aided by downward rain-carriage of the loosened, soil — a 

 process which, he adds, is visibly going on wherever a hill-side is 

 under cultivation. 



9. Professor Harkness contributes a paper on the Middle 

 Pleistocene Deposits, having reference to the beds in England, 

 Scotland, and Ireland. 



10. Mr. B. Tate furnishes some notes on new and little-known 

 Liassic Brachiopoda, and gives a table showing the distribution of 

 all the species known to occur in the Lias of Britain. 



11. The Earl of Enniskillen, following Sir P. Egerton's example, 

 supplies an alphabetical catalogue of type-specimens of Fossil Fishes 

 in his collection at Florence Court, which he also adds are open to 

 the inspection of any geological or palasontological student. 



12. Mr. W. H. S. Westropp notices the occurrence of Albite in 

 the granite of Leinster.
