CARBONIFEROUS LAMELLIBRANCHIATA. 



Pteronites persulcatus, M'Coy, and Myallua, sp. doubtful, as the two kinds of 

 "muscle." ^ 



1809. Nothing further seems to have been noted till W. Martin brought out 

 his ' Petrefacta Derbiensia ' in 1809. He refers all fossil forms to living repre- 

 sentatives. Only four forms of Lamellibranchs are described in the work : 



Conchyliolithus Arcites caneeUaius = Area. 



„ „ rostratus = Conocardium. 



„ Pinnites flabeJliformis = Pinna. 



„ 3Iya ovalis =• Carhonicola ovalis. 



1813-18. Very few Carboniferous Lamellibranchs were described or figured by 

 Sowerby in his great work, ' The Mineral Conchology.' The following genera and 

 species are described and figured : 



Sanguinolaria gibhosa. 

 Cardium Hihernicum. 



— elongatum. 

 Tnoceramus vetustus. 

 Isocardia ohlonga. 



Nucula Palmes. 

 Pecten granosus. 



— papyraceus. 



— plicatus. 



In 1828 Fleming (' Hist. Brit. Anim.') recapitulates, with a short description 

 in each case, those Carboniferous species which had already been described by 

 previous writers, and in some cases (MijtiluH crassus, CorJmla limosa) by himself, 

 and at the same time describes most carefully Hiatella sulcata and Corhula limosa 

 from Carboniferous strata. No figures, however, of the new shells are given. The 

 following species are enumerated : 



Sanguinolites gibhosa. 

 Siafella sulcata. 

 Corbula limosa. 

 Cardium alxforme. 

 Isocardia oblong a. 

 TJnio JJrei. 

 Modiola bipartita.'^ 

 Mgtilus crassus. 



Pinna flahelliformis. 

 Nucula palmce. 



— atlenuata. 



— gibhosa. 

 Area cancellata. 



— rostrata. 

 Pecten dissimilis. 



— papyraceus. 



In 1829 Honinghaus published a list of fossils in the Museum of the University 

 of Bonn (' Verzeichniss der dem Museum der Universitiit Bonn,' Petrefacten- 

 Sammlung), giving the localities whence each species was obtained, but nothing was 

 attempted in the way of description or illustration. 



1828. In ' Zeitschrift fiir Mineralogie,' vol. i, for 1828, H. G. Bronn, on p. 262, 



' Ure's collection is now in the Museum of the Royal Society of Edinburgh. 



2 The specimens of M. hipartita figured by Sowerby in the ' Min. Conch.' are from Parkham 

 Park, Surrey, and therefore not Carboniferous. Sowerby, in his remarks on that species, says that certain 

 shells from Llantrissant, near Cardiff, belong to the same species^ but does not figure them. This 

 name, therefore, cannot be used for a Carboniferous shell.
