58 REPORT — 1864 



Notice of some Geological Appearances in the North-west of Morocco. 



By Dr. T. Hodsein. 



On the Coal-measures of New South Wales ivith Spirifer, Glossopteris, and 

 Lejjidodeudi'on. By William Keene, Examiner of Coal-fields and Keeper 

 of Mining Records, New Suuth IVales. 



A geological map of the country, as far as examined by the author, and a general- 

 ized section, illustrated this paper, which referred, hrst, to the existence of Belem- 

 nites (indicating Secondary rocks) near the River Belliando in Queensland ; 2nd, 

 the siliceous fern-shales, with dicotyledonous leaves, from the southern part of New 

 South Wales, which the author thinks to be older than the Coal-measures ; 3rd, the 

 false Coal-measures, or Wyanamatta shales, in the upper part of the Sydney Sand- 

 stone ; 4th, the existence of eleven workable seams of coal in the true Coal- 

 measures of New South Wales, and the occurrence of Vertebruria and Glossopteris 

 throughout the eittire series. Pachydomus and Belkrophon (abundant) and Spirifer 

 (rare) are found towards the lowest seams ; and here, as well as lower down, 

 Spirifer, Fenestella, and Orthoceras abound. A Heterocercal tish has also been 

 found in the shale above the ' yard seam.' Siliceous grits underneath the lowest 

 seam contain Lcpidodendron {Pachyphla-us). 5th. The author alluded to the 

 volcanic phenomena of the Peale Ranges, which have been upheaved since the 

 Coal-period ; indeed in some of the lavas Mr. Keene found a fieshwater mussel of 

 a probably existing species. 6th. Referring to the auriferous quartz-rocks, shales, 

 and fossiliferous limestones, on whicli the Coal-measures lie unconformably, the 

 author stated that he believed these older rocks were mutually connected, and 

 belonged to one and the same system of strata ; and that, besides gold, the 

 quartz was rich mth copper- and iron-ores. An illustrative series of specimens 

 accompanied the paper ; and the author referred to a stUl hner collection deposited 

 in the Bath Museum in 1862. 



On the Species of the Genus Pteraspis. By E. R. Lankestek. 

 In this paper the author first reviewed the present state of our knowledge of 

 those remarkable fossils of the Old Red Sandstone, the Cephalaspis and Pteraspis, 

 which he stated was in a very imsatisfactory condition. Cephalaxpis had been 

 taken in hand by Sir Philip Egerton, but Pteraspis was in a state of complete con- 

 fusion. His friend Prof. Huxley had intended to work at the latter genus, and had 

 made drawings and notes for the pm-pose, but had finally relinquished his inten- 

 tion, and handed his material very kindly to the author. From this and other 

 material at his disposal, the author was enabled to establish three genera, Pferas^ns, 

 Cyathaspis, Scaphaspis, in place of the one Pteraspis. In the first, the shield con- 

 sists of seven separable pieces ; it includes Pi!, rosfratus, Ag., Pt. Crouchii, Salter. 

 In the second genus, Cyathaspis, the head-plate is separable into four pieces only ; 

 it contains Cyatliai^pis Banksii, and a new species, Cy. Symondsii. The last genus 

 is characterized by the shield being composed of one simple, oval, indivisible plate. 

 Scaphaspis includes Sc. Llitydii, Sc. Lewisii, Sc. truncatus, and Sc. ludensis. 



0^ the Boulder-clay and Drift of Scarborough and East Yorkshire. 

 By John Leckenbt, F.G.S. 

 The post-tertiary beds in the north-east of Yorkshire exhibit distinct traces of 

 glacial action. At Scarborough they attain a thickness of rather more than 200 

 feet. The fossils collected in the boulder-clay at that place by the author, and in 

 the sapie material at Whitby, by Mr. Jefti-eys, represented thirteen species. All 

 of them are marine ; they inhabit high latitudes, and (with two exceptions, viz. 

 Astarte horealis and Tellina calcaria) also the British seas. Mya truncata var, 

 uddevallensis is also extinct as a variety in om- seas.
