12 i Geological Remarks on tke 



VilUpTSiix 3 has coarse limestone quarries, and 



iheir accompanying fossil remains, (as at Gentilly) 

 with the covering strata such as occur at Saint Ger^ 

 main, p. 48. 



VillersCotteret, 31 miles NE., has madrepores, with ca- 

 merines and other well preserved shells^ and grains of 

 coarse quartz, that together make a sort of pudding- 

 stone, p. 47. 



Yirqflay, Q\ miles SW. The gypsum formation has here 

 no plaster beds in it, but green marles containing stroii- 

 t^an prevail, p. 53. 



An Alphahetical lAst of the Fossils or Organic 'BemainSy 

 which are mentioned by Messrs. Cuvier and Brogiiiart as 



found within the Basin of Paris ; with the Names of the 

 Places, and of the Strata which produce them, iviih Re- 



Jerences to the Pages in the Philosophical Magazine^ and 

 Remarks in parentheses, 



A^ianchit e s {Y.ch\m}), the shells of calcareous spar, filled 

 with black liint, in the chalk strata, p. 4?. 



Anomltes, three Terebratula shells in the chalk strata, p. 42. 



Antelopes, bones of unknown species, iu the alluvium (of 

 valleys), p. 58. 



Balani shells, in the freestone at top of Montmartre, at 

 Romainville, Saint Prix, Montmorency, Longjumeau, 

 &c. p. 54. 



J^elemnites, in the chalk strata; these differ from those 

 found with ammonites in compact lime*, p. 42. 



^ir£?55 skeletons of unknown ones, at Monimartre, &c., in 

 the first or upper gypsum mass. p. 51. 



Calypirce shells, at Chaumont, Gentilly, Grignon, Gncs- 

 pelle, Issy, Longjumeau, IMeudon, Monimartre, 

 Montmorency, Pallary, Romainville, Saint Prix, Se- 

 vreb, Vaugirard, &ft. in the lower beds of the coarse 

 limestone, and in the freestone, p. 47, 54, and 55. 



Camerine shells, at Chantilly, Ganelon mount, Onin 

 mount, Vaucienne, Villers-Cotteret, &c., either in the 

 lower beds of the coarse limestone, or in a siliceous 

 puddingstone. p^ 47 and 48. 



♦ The limestone here spoken of, does not seem to belong to the basin of 

 Paris, and I should be very glad to le^rn, whether it is any where dug in 

 France ? In the great argillaceous formation between the Bath Frecs>tone 

 and the blue Lias soils, in this country, there is a stratum of limestone called 

 by Mr. Smith the blue marle-stotw, which contains very perfect belemnitc5, 

 MTJall cornu-ammoni and asteria. The limestone of Oakham, and of Maidwell, 

 between Northampton and Alarket-Harborouj^h, belongs I believe to this 

 itratum, but 1 never had the opportunity of collecting any specimens at tha 

 latter place.
