 Geological Society of France, at their meeting on the 7th of May, 

 1860 (see Bull, de la Soc. Geol. de France, toI. xvii.), he gave it as his 

 opinion that the Paradoxides Harlani, Green, is identical with the 

 Paradoxides spinosus, Bqeck. An opinion coming from one who is 

 so eminent in science, and whose work on the " Systeme Silurien du 

 Centre de la Boheme " stands as an everlasting monument to his learn- 

 ing and untiring zeal, is certainly worthy of being carefully weighed 

 before venturing to doubt it. But when we remember the imperfect 

 means of comparison which M. Barrande had at his command, wan1>- 

 ing some of the most characteristic portions of the animal, we can 

 easily imagine that with all his scientific acmnen, and accurate 

 knowledge of Trilobites, he should fail to establish the difference 

 between the two species under discussion. 



This being a point of some local interest, as well as having a bear- 

 ing on the question of the distribution of species in the Primordial 

 fauna, I have thought it not unworthy of attention. Having had
