Nomenclature of the Foraminifera. 343 



Fortis * invented the name " Discolithes " as a general appel- 

 lation for the small and mostly discoidal fossils previously known 

 as " pierres lenticulaires, numismales, frumentaires, helicites, et 

 dernierement camerines," — that is Nummulince (including Assi- 

 linae), Orbitoides, Orbitolites, some discoidal and polygonal Cal- 

 carince, Alveolince, and Fabularia. 



33. Vol. i. p. 190. 48 e genre. Archaias spirans. This is in- 

 tended for Orbiculina angulata, F. & M. 



34. Vol. i. p. 194. 49 e genre. Helenis spatosus. Of the figures 

 here given by De Montfort the upper one is referable to Orbicu- 

 lina adunca, F. & M. ; the lower one is a bad copy of the section 

 of O. Orbiculus. 



35. Vol. i. 198. 50 e genre. Botes rotalitatus. A bad copy of 

 Fichtel and Moll's figure of Orbiculina Orbiculus, 



36. Vol. i. p. 202. 5 l e genre. Themeon rigatus. This is the 

 common Polystomella crispa, Linn. 



37. Vol. i. p. 206. 52 e genre. Cellanthus craticulatus. Badly 

 copied from Fichtel and Moll's figure of Polystomella craticu- 

 lata. 



38. Vol. i. p. 210. 53 e genre. Nonion incrassatus. This is the 

 " Nautilus incrassatus " of Fichtel and Moll. D'Orbigny's ge- 

 neric term Nonionina, modified from De Montfort's " Nonion/' 

 is applicable to this form, but only as a subsidiary term, not 

 even of subgeneric value in a zoological sense, though often use- 

 ful in descriptions and catalogues. The Nonionince are weak 

 varieties of Polystomella. 



39. Vol. i. p. 214. 54 e genre. Robulus cultratus. Cristellaria 

 Calcar, var. \, F. & M. One of the most common of the whole- 

 keeled Nautiloid Cristellaria. D'Orbigny founded his Robulina 

 on this form, which has a triangular aperture, — a feature of ex- 

 treme variability. 



40. Vol. i. p. 218. 55 e genre. Patrocles querelans. Fichtel 

 and Moll's var. rj of Cristellaria Calcar is here intended. 



41. Vol. i. p. 222. 56 e genre. Spincterules costatus. This 

 represents Cristellaria costata, F. & M. 



42. Vol. i. p. 226. 57 e genre. Clisiphontes Calcar. This is 

 Fichtel and Moll's var. a of Cristellaria Calcar. De Montfort, 

 who gives Buffon's 'Mollusq.' (Sonnini) pi. 47. fig. 4, and 

 Soldani's ( Testaceogr.' as affording the original figure of his 

 illustration, says that this shell abounds on the coasts of Borneo 

 and Java, as well as in the Mediterranean. 



43. Vol. i. p. 230. 58 e genre. Herion rostratus. Cristellaria 

 Calcar, var. e, F. & M.
