TRILOBITES 



OCCUEEING IN THE 



CARBONIFEROUS LIMESTONE, &c. 



1. 1809. Mr. W. Maetin, in his ' Petrificata Derbiensia,' publislios, under the 

 name of Entomolithus (Oniscitcs) Derhiensis, the earhest description extant of a 

 Carboniferous Trilobite. Under the genus Phillqjsia, we give Martin's careful and 

 interesting description of this fossil, which he considered to be " an insect, related 

 to Oniscus." 



2. 1822. MM. Alex. Brongniart and A. G. Desmarest, in their ' Histoire 

 Naturelle des Crustaccs Fossiles,' p. 145, pi. iv, fig. 12, under the name of AsaplmSy 

 figure a pygidium of Phillipsia from the black Carboniferous Limestone in the 

 environs of Dublin. 



3. 1823. Baron Ernst F. von Schlotheim, in his ' Nachtrage zur Petrefacten- 

 kunde,' Gotha (ii Abtheil, pp. 42-3), refers to a pygidium of a Trilobite 

 which he also figures on plate xxii, fig. 6, under the name Trilobites, Asaphus 

 puskdatus (vel pustulosus, see explanation of plate accompanying Atlas, p. 22), 

 said to be from the youngest Upper Transitional Limestone of the Eifel. This is 

 no doubt a Devonian Trilobite, but the name having been adopted by de Koninck 

 it has become incorporated in the nomenclature of these later species with which 

 it has no afiinities. 



4. 1825. Edouard d'Eichwald, in his ' Geognostico-zoologicse per Ingriam 

 marisque Baltici Provincias, nee non de Trilobitis observationes ' (Casani), 

 notices and figures, at p. 54, tab. iv, figs. 4 and 5, two pygidia of Trilobites, which 

 he names, " AsapJms Brongniarty " (sic), fig. 5, and " A. Eichwaldi/' fig. 4, on the 

 authority of Fischer de Waldheim. 



5. 1829. Friederich Holl, in his ' Handbuch der Petrefactenkunde ' (Dres- 

 den), p. 176, records Asaphus (Phillipsia) Brongniarti, and A. {Phil.) Eichivaldi, 

 Fischer, in his list of Trilobites. 



6. 1832. A. H. DuMONT, in his ' Mcmoire sur la Constitution Geologique de 

 la Province de Liege,' ' Memoires Couronncs par 1' Academic Royale de Bruxelles,'
