species be spread over so great an extent of country ; but no 

 difference can be established except on the size and thickness ; 

 and so it is difficult to fix it in^ this respect/' See also Ann. 

 Nat. Hist. ser. 3. viii. p. 334. 



66. Nummulites concava, Defr. 1825. Diet. xxxv. p. 325. 

 " White, like ivoiy." Brought from the Crimea by Dr. E. D. 

 Clarke ('^par le celebre voyageur Klark"). "It has a little 

 round central cavity in the interior, is complanate ;" " probably 

 those from Cairo are the same.'' Hence probably it is a variety 

 of N. complanata. Ann. Nat. Hist. /. c. p. 234. 



67. Nummulites globularia. Lam. Diet. xxxv. p. 224. A 

 globular variety of A^. Icevigata, as Defrance judiciously suggested. 



68. Nummulites laevigata, iJrw^Miere. Diet, xxxii. p, 179, xxxv. 

 p. 224 ; Bl. Malac. p. 372. Nummulina lavigata : a subtype, 

 characterized by inosculation of the septa of the alar lobes. 

 See Ann. Nat. Hist. ser. 3. v. p. 290, & viii. p. 232. 



Defrance remarks, — " II est extreraement probable que c'est 

 la meme espece, modifiee par les localites, que I'on trouve en 

 Suisse, dans le Veronnais, en Dalmatic, sur le mont Pilate pres 

 de Lucerne, k Stubbington dans le Hampshire, et dans d'autres 

 endroits." 



69. Nummulites(?) Lenticula, Defr. 1825. Diet. xxxv. p. 226, 

 Sienna, Pisa, Vicentin, Oise, La Somme, Belgium, &c. This is, 

 according to D'Archiac and Haime, an Amphistegina (Monogr. 

 p. 161) ; and, judging from specimens brought from Pisa, we 

 are of the same opinion. 



70. Nummulites lenticularis, De Bl. Diet. ; Atlas, Conch. 

 pi. 11. f. 2; Bl. Malac. pi, 4. f. 2. This is in the index to the 

 Atlas, not in the text. It is Nummulina Icevigata, Bruguiere. 



71. Nummulites Lenticulus, De Bl. 1824. Diet, xxxii. p. 179; 

 Malac. p. 373. Lycophris lenticularis, De M. ; Fichtel & Moll's 

 Nautilus lenticularis, var. yS. A small granulose Nummulina [N. 

 Lucasana, Defr. var. a, D'Archiac and Haime). De Blainville 

 says, " Of a species of this section {Lycophris, De M.) Defrance 

 makes a genus of ' Polypiers.' " Apparently they mistook a 

 rough Orbitoides for the little granular Nummulite figured and 

 described by Fichtel and Moll, and subsequently by DeMontfort. 

 See Ann. Nat. Hist. ser. 3. v. pp. 108, 110, vi. p. 342, and viii. 

 p. 233. 



72. Nummulites Moneta, Defr. 1825, Diet. xxxv. p. 226. 

 One inch wide. Bonca ; Dalmatia ; lowest beds of the Isles of 

 Veglia, Pago, and Arbe; Croatia; Alicante. According to 

 D'Archiac and Haime, this is the iV. Spira of Roissy, " Discolithe 

 no. 6 " of Fortis. An Assiline form of Nummulina. 



73. Nummulites Ramondi, Defr. 1825. Diet. xxxv. p. 226.
