Dr. J. W. Gregory — Egyptian EcMnoidea. 149 



GrifiSth was President of the Geological Section of the British 

 Association at the Dublin Meeting, that he was able to publicly 

 exhibit in a complete form his Geological Map of Ireland. In the 

 following year, the Irish Government ordered this map to be 

 reconstructed and engraved on a scale of one inch to four miles by 

 the Board of Ordnance. Before the map could be issued, however, 

 Griffith drew up for the Railway Commissioners a work entitled 

 an " Outline of the Geology of Ireland," which contained a reduction 

 of his map, with many of the details omitted. This small map, 

 which was issued in April, 1838, must be regarded as the first 

 complete geological map of Ireland that was regularly published. 

 1 have not been able to ascertain whether any of Griffith's earlier 

 manuscript maps are in existence. In August, 1838, the large 

 geological map of Ireland appears to have been exhibited at the 

 British Association Meeting in Newcastle ; but it was not regularly 

 published till March, 1839. A second edition of the map was 

 published in 1855 by order of the Treasury. 



The Wollaston Medal, which was in 1831 awarded to William 

 Smith for his Geological Map of England and Wales, was in 1854 

 presented to Sir Richard Griffith for his Geological Map of Ireland. 

 The three pioneer Geological Maps of England, Scotland, and Ireland 

 have now been placed in juxtaposition in the geological gallery 

 of the Science Division of the South Kensington Museum, where 

 they are open to examination and comparison with the earliest 

 geological maps published in France and other countries. A 

 study of these maps will serve to demonstrate the priority claimed, 

 and justly claimed, by Fitton, for the geological maps of this country 

 over those of any other part of Europe. 



The Geological Map of the Basin of Paris by Cuvier and Brongniart 

 was published in 1810, while William Smith's early maps had 

 appeared in 1799 and 1801 ; and the maps of England, Scotland, 

 and Ireland, by Smith, Macculloch, and Griffith respectively, were 

 published in 1815, 1835, and 1838, the first complete Geological 

 Map of France, that of Elie de Beaumont and Dufrenoy, making 

 its appearance in 1840. 



II. — A Collection of Egyptian Fossil Echinoidea. 

 By J. W. Gregory, D.Sc, F.G.S. 

 (PLATES V AND VI.) 

 rilHE first collection of Egyptian fossils sent for determination by 

 X Captain Lyons, R.E., Director of the Egyptian Geological Survey, 

 to the British Museum, includes an interesting series of Echinoidea, 

 which has been intrusted to me for examination. It is hardly 

 necessary to state that our knowledge of the fossil echinid faunas of 

 Egypt is mainly due to M. P. de Loriol-le-Fort, who has described 

 a large series in two admirable monographs.'
