TRANSACTIONS OF SECTION C. 



For some years past a committee of Littleborougb and Rochdale geologists, 

 couslsting of Messrs. H. Suteliffe, Walter Baldwin, W. A. Parker, S. S. Piatt, and 

 others, have devoted themselves to the task of working out the beds of shale con- 

 taining clay ironstone nodules, a portion of the middle Coal Measures at Sparth 

 Bottoms, half a mile south-west of Rochdale Town Hall, in beds estimated to 

 occur 135 feet above the Royley Mine coal-seam. 



In the clay ironstone nodules occur well-preserved ferns, Calamites, Sifjillarim, 

 remains of Carbonicola acuta and other Coal Measure lamellibrancbs, whilst the 

 number of artbropoda is probably unsurpassed in any locality of this formation. 



The first to be noticed was described in 1904 by Messrs. Baldwin and Suteliffe,' 

 under the name of Eoscorpius spathensis. 



The subsequent finds have been confided by the committee to the author to 

 report upon, and are as follows : — 



PrestivieMa anthrax, head shields (traces 

 of limbs). 



Prestwiohia rotundata, var. viajor (var. 

 nov.) 



Prestwichia rotundata var? (or (E) 

 Banare ?) 



Prestwichia Birtmnlli. 



Bellinurus longicaudatus, H. W. (in Cala- 

 mi te) (sp. nov.) 



Bellinurus Baldwini, H.W. sp. nov. 



Bellimirus Koenigianus. 



Bellinurus Bellulus, Konig. 



Eurypterus Moysei, Coal Measures 

 (Ilkeston). 



Pijfjoceplialus Cooperi (Sparth and Coal 



Measures, Dudley). 

 Anthrapalcenion Parheri, H. W. sp. nov., 



Sparth. 

 Anthracomartus trilohitis (Scudder). 

 GeraUnura Sutcliffei, H. W. sp. nov. 



Sparth. 

 Mazonia (sp. nov.) Sparth. Cf. Mazonia 



Woodiwna (M. and W.) 

 Xylohuis PJattii, H. W. sp. nov., Sparth. 

 Uu2)hoberia spinulosa, Scudder. 

 Stenodictya lohata 1 Brong. (probably 



new). 



These last named belong to the Stenodictyopterida of Brongniart (Proto-epheme- 

 rida), and represent a very early and generalised group of large flying neuropterous 

 insects, abundant in the Coal Measures of Allier, but very rare here. 



The following is a list received from Mr. Robert Kidston, F.R.S., of fossil 

 plants determined by him from the Middle Coal Measures, Sparth, at a horizon 

 40 yards above the Arley Mine and 40 yards below the Neddy Mine. 



Dactylotlieca plumosa, Avtrs. sp. 

 Mariopteris imiricata, Schl. sp. 

 Alethopteris lonchltica Schl. sp. 



„ valida, Boulay. 



Neumpteris impar, Weiss, sps. 

 Cyclopteris trichomanoides, Brongt. 



Spiropteris, sp. 



L'alamocladus equisetiformin, Schl. sps. 



„ char rpfor mis, Sternt. sps. 



Sphenophyllum cimecifolium, Sthg. sps, 



var. saxifraga'folium. 

 Lcpidophyllum majvs, Brongt. 



Fossil of doubtful affinity : — 



Vetacapsula Cooperi (Mackie & Crocker). 



2. TJie Jurassic Plants Jrom the Rocks of East Yorkshire. 

 By A. C. Seward, M.A., F.B.S. 



Historical. — The work of Young and Bird, entitled 'A Geological Survey 

 of the Yorkshire Coast,' was published at Whitby in 1822. William Bean, John 

 Williamson, and William Crawford Williamson rendered excellent service in the 

 early days of the geological exploration of the Yorkshire coast. Several speci- 

 mens collected by local naturalists were sent to Adolphe Brongniart, and described 

 by him in his ' Histoire des Vegetaux Fossiles,' published in 1828. The publica- 

 tion in 1829 of ' Illustrations of the Geology of Yorkshire,' by J. Phillips, placed 

 the geology of East Yorkshire on a sound scientific basis. Numerous species of 

 Jurassic plants from the Yorkshire coast were figured and described in the ' Fossil 



' Q. J. Geol. Soc, vol. Ix. p. 396, fig. 2.
