1 . Notice of the Fossils of the PalcBozoic beds of the province of 

 AsTURiAs, in the North o/" Spain. By M. E. de Verneuil and 

 the Count d'Arciiiac.

[The subjoined extract forms the Appendix to a memoir read before the French 

 Geological Society on the 19th of May, 1845, entitled " Researches concerning 

 some of the rocks which constitute the province of the Asturias," by M. Adrien 

 Paillette. M. Paillette describes successively, but briefly, the position and locali- 

 ties of the principal rocks, some of which he found to resemble very closely the 

 beds of the same age in Brittany and Normandy. These rocks include Silurian, 

 both lower and upper, Devonian, and Carboniferous strata, the latter containing 

 important beds of workable coal. The carboniferous beds are greatly disturbed 

 and dislocated, and the author proposes to continue their investigation in greater 

 detail before publishing any general conclusions.— Ed.] 



Our knowledge of the faunas of the various departments of the 

 Palaeozoic series of formations is not yet sufficiently complete, or 

 deduced from observations of a sufficient degree of generality, to 

 enable us to determine the age of any one of them by the presence 

 of a single species of fossil; but this is not the case when we have 

 before us a group of fossils from the same locality, obtained from 

 beds whose mutual relations are well established. The following 

 list, therefore, of the organized bodies obtained by M. Paillette from 

 the deposits which he has so well studied and described, will enable 

 us to draw certain conclusions, tolerably definite, as to the period 

 of their deposit, by comparing them with what we already know 

 with regard to other parts of Europe.
