110 REPORT-—1840. 
who, from an examination of certain fossils sent to him from thence, 
had become convinced @ priori, that the same palzozoic succession 
would there be found as in the British Isles. Mr. Murchison gratefully 
acknowledged his obligations to the Baron A. von Humboldt, and dwelt 
with pleasure on the assistance which his fellow-traveller and himself 
received from the Baron A. de Meyendorf, now executing, by order 
of His Imperial Majesty, assisted by M. Zenofief, a statistical survey 
of parts of Russia, who endeavoured to make his tour correspond to 
some extent with that of the authors, and who enriched his expedition 
with two excellent naturalists, Count Kayserling and Professor Blasius. 
Mr. Murchison further took this public opportunity of testifying his 
sincere thanks to the Russian authorities who aided this geological in- 
quiry, among whom he particularly enumerated their Excellencies the 
Count de Cancrine, Count Nesselrode, Count Alexander Strogonoff, — 
Baron Brunnow, and General Tcheffkine*. And he further expressed 
his sense of the value of the services of a zealous young geologist, 
Lieutenant Koksherof, without whose aid the authors could not have 
accomplished their task. Maps and a section illustrated the description, 
and selections of the characteristic fossils of each group were laid upon 
the table. 
On the Yellow Sandstone, and other points of the Geology of Ireland. 
By R. Grirritu, F.G.S. 
Mr. Griffith exhibited his new corrected map of the geology of 
Ireland, and a series of specimens in illustration and confirmation of 
several changes, especially in the south of Ireland, which he had 
thought it right to make since the first appearance of the map. A 
feature of the map, of much importance, was the subdivision of the 
mountain limestone series, and the extension of the colour for mill- 
stone grit over districts formerly classed as true coal measures. The 
yellow sandstone was particularly described in different districts, and 
specimens, in a regular series, of the organic remains in the Silurian 
and Carboniferous groups of Ireland, were exhibited to the Meeting. 
On the occurrence of two Species of Shells of the genus Conus, in the 
Lias, or Inferior Oolite near Caen, in Normandy. By Cuarvrs 
Lye.LL, F.R.S. GUS. 
Fossil shells of Lamarck’s family “ Enroulées” abound in many 
tertiary formations, but scarcely any examples are recorded of their 
occurrence in older strata. The six genera comprised in this family 
are Ovula, Cyprea, Terebellum, Ancellaria, Oliva, and Conus. Four 
of these appear never yet to have been found, either in the chalk or 
any older rock. Of Cyprea, one species has been discovered in the 
upper chalk of Faxde, in Denmark ; and M. Dujardin obtained from 
the chalk, near Tours, a Cone, which he has called C. tuberculatus. 
* General Tcheffkine, Major-General of the School of Mines at St. Peters- 
burgh, and Professor Jacobi, of the Imperial Academy of Sciences, were present 
at the Glasgow Meeting.
