3. "Further Remarks on Adherent Carboniferous Productidae." 

 By R. Etheridge, jun., Esq., F.G.S. 



The author stated that since the reading of his former paper on this 

 subject (Q. J. G. S. vol. xxxii. p. 454) his Productus complectens had 

 been found in various localities, as in Northumberland, in Fifeshire, 

 and near Dairy, in Ayrshire. The last-mentioned may be a distinct 

 species. He further described two specimens of adherent Produc- 

 tidte (one from Scremerston quarry, Northumberland, near Berwick, 

 and one from Kinghorn, in Fifeshire) the characters presented by 

 which led him to refer them to the genus Qhonetes. 



4. " The Submarine Forest at the Alt Mouth." By T. Mellard 

 Reade, Esq., F.G.S. 



The right of the remains of trees on the shore at Great Crosby, 

 in Lancashire, to be regarded as representing a submerged forest 

 having been called in question, the author desired to place on record 

 the results of an investigation which, he thought, would dispose of 

 all doubts on the subject. On cutting a trench through 1 foot of peat 

 and 14 inches of clay round one of the stumps, which had an oak-trunk 

 lying by it, apparently in the position in which it had fallen, the 

 observers saw that roots were cut through all round, running along 

 near the surface of the clay, or penetrating it diagonally ; while 

 rootlets and tap roots descended vertically into the clay. Sevei-al 

 of the main roots were traced for a considerable distance into the 

 clay. On raising the stump out of the ground, the clay showed 

 numerous root-sections. The examination of the stumps gave con- 

 firmatory results.

" On the Paloeoutological Results of the recent Polar Expedition 

 under Admiral Sir George Nares, K.C.B., F.R.S." By Capt. H. W. 

 FeUden, R.A., F.G.S., and Robert Etheridge, Esq., F.R.S., F.G.S. 



In this communication the authors brought before the Society the 

 pala3ontological results and details of the collection made by the 

 naturalists and other officers of the late expedition to the Arctic 

 Circle under Admiral Sir G. Nares. The purpose of the paper was 

 to record the presence of Silurian and Carboniferous fossils in the 

 highest latitude yet reached, 82° 45' N. Of the former group 60 

 species have been determined, ranging from the Lower to the Upper 

 Silurian, both Llandeilo and Wenlock types being present and 

 numerous — notably, in the class Heteropoda, two species of the genus 

 Machirea, and BelleropJwn , with Stropliodonta and Raphistoma, &c., 

 also the genus Receptaculiics. Upper- Silurian species of Actinozoa 

 belonging to Ilahjsitcs, FdvoslU's, ITelioIites, FavisleUa, Zaplirentis,
