 with Descriptions of a new British Carboniferous Genus 

 and some new Devonian Species from Spain. By R. 



Etheridge, Jun., and P. Herbert Carpenter, M.A., 



Assistant Master at Eton College. 



1. Introduction. 



Since the appearance of our previous paper * upon the 

 morphology of the Blastoids, we have been enabled, thanks to 

 the kindness of many friends, to considerably extend our 

 researches in this interesting order of the Pelmatozoa. New 

 material has been sent us by Mr. C. Wachsmuth, of Burling- 

 ton, Prof. A. G. Wetherby, of Cincinnati, Prof. W. H. Bar-

 Illinois, Prof. F. Romer, of Breslau, Profs. A. Gaudry and 

 E. Perrier, of Paris, and Don Lucas Mallada, of the Mining 

 School in Madrid. All these gentlemen have responded to 

 our inquiries with the most liberal kindness, for which we 

 tender them our heartiest thanks. 



We have also received some valuable corrections with re- 

 gard to the stratigraphical position of certain species. Fol- 

 lowing what we believed to be good authority, we referred 

 the doubtful Pentremites Bomeri, Shum., to the Chemung
