the beds, "which, were much contorted, and remarked that a seam of 

 coal had been met with seven feet below the Limestone. 



The Gteological Society of G-lasgow. — I. The Conversazione: 

 of this Society was held on November 2 ; the attendance was very 

 numerous, and a great variety of interesting geological objects was 

 exhibited. The chair was occupied by the President, James Smith, 

 Esq., F.E.S., of Jordan Hill. 



n. — The first monthly meeting, session ISGStBG, was held in the 

 Andersonian University, on the 9th of November. Edward A. 

 Wunsch, Esq., Vice-President, in the chair. Seventeen new mem- 

 bers were elected. The secretary exhibited and described a new 

 chart of Fossil Crustacea, arranged and drawn by Messrs. J. W, 

 Salter, F.G.S., and Henry Woodward, F.G.S., &c. This chart is a 

 most interesting and valuable one. It contains upwards of 490 

 figures beautifully engraved by Mr. J. W. Lowry, and not only 

 shows at a glance, between transverse lines, the various genera of 

 crustaceans belonging to each of the geological formations, but also,, 

 between curved vertical lines, the first appearance, gradual develop- 

 ment, and range in time, of each of the several orders, from the 

 Cambrian period to the present, the top transverse section contain- 

 ing recent typical forms illustrative of the fossil groups figured 

 below. He also exhibited and briefly described several fossils new 

 to the Scottish Carboniferous faima, including one new to science. 

 These fossils were from the Upper Coal-measures of Kilmaurs, finely 

 preserved in clay-ironstone nodules, and identical with those found 

 in similar nodules about Coalbrookdale, in the Shropshire Coal-field. 

 They consist of ferns and other plant remains. There were also 

 several specimens of the Limiiliis rotundaius, one of which showed a 

 peculiar prolongation of the carapace (?), which Mr. Henry Wood- 

 ward said he had never seen in the numerous specimens from the 

 Coal Measures which had passed through his hands. The Secretary 

 referred to it as a link in a curious series of the modification of an 

 organ, as shown in some of the Eurypterida and Limididce in the 

 chart. He then drew attention to a perfect and beautiful specimen 

 of a Bellinurus bellulus of the family LimuUdce, also from Kilmaurs, 

 which he described, and contrasted with a specimen of the recent 

 Idmulus Moluccanus from the Indian Ocean. — The Eev. H. W. Cross- 

 key then took the chair, and Mr. Wunsch read a paper by himself 

 and Mr. John Young, of the Hunterian Museum, on his " Discovery 

 of fossil trees buried in volcanic ash in Arran" (see Geological 

 Magazine, October, 1865, p. 474), 



in. — At the monthly meeting on the 7th December, Eev. H. W. 

 Crosskey, V.P., in the chair, Mr. John Young called attention ta 

 some interesting corals from the Carboniferous limestone presented 

 to the Society by Mr Linn. Mr. James Bennie read a paper on the 

 " Surface Geology of Glasgow," as illustrated by the excavations 

 for the Windmillcroft Dock, the Mavisbank Quay, and for numerous
