This appears to have been the first of the coin-shaped Fora- 

 miniferSj so common in the fossil state as to attract the notice of 

 peasant and of naturalist at an early period, that was subjected 

 to zoological classification under a binomial appellation. A 

 common form in the Eocene Tertiaries of the west of Europe, 

 of large size, and elegantly lenticular in its shape, this was the 

 most prominent of the French Nummulites; and its usual 

 smoothness of surface gave rise to its present trivial name ; and 

 its tuberculate variety {N. scabra) was subsequently catalogued 

 as a different species. The task of sifting the many names that 

 have been given to the several forms of European Nummulites 

 has been carefully accomplished by d^Archiac and Haime in 

 their fine Monograph on the Fossils of the Nummulitic Strata 

 of India (4to, Paris, 1853). In the list of synonyms of N. Ice- 

 vi(jata, which is very long (o/:». cit. p. 103), they have given as 

 the first regular name " Ilclicites lenticularis ;" but Burtin terms 

 it only la (jrande Helicite ou Lenticulaire. Bruguicre classified it 

 first under the appellation of Camerma laevigata (Encycl. Meth. 

 ] 789) ; this was modified to Nummulites Icmviyata by Lamarck 

 (1801), and to Nummulina lavigata by D^Orbiguy (182G). 

 MM. d'Archiac and Ilaimc have described and illustrated this 

 species in much detail {op, cit. p. 101, pi. 4. f. 1-7). Dr. Car- 

 penter also had previously done much to elucidate its structure.
