47. 186G. Dr. H. B. Geinitz, in his ' Carbonformation und Dyas in Nebraska ' 

 (Dresden, pp. 102, with five plates), figures and describes a Fhillqjsia, from 

 the limestone of Plattesmouth, Nebraska (p. 1, pi. i, fig. 1). 



48. 18G7. Valerian von Moller contributed to the ' Bulletin de la Societe 

 Imperiale des Naturalistes de Moscou,' a paper, " Ueber die Trilobiten der Stein-

 Carboniferous Trilobites from Russia, and gives a most excellent catalogue of all 

 the species already described from that formation. 



49. 1867. Sir R. I. Murchison, in his ' Siluria ' (4th edition, p. 209, Fossils
