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, hélicites, et 
derniérement camerines,”— that is Nummuline (including Assi- 
line), Orbitoides, Orbitolites, some discoidal and polygonal Cal- 
carine, Alveoline, and Fabularia. 
33. Vol. i. p. 190. 48° genre. Archaias spirans. This is in- 
tended for Orbiculina angulata, F. & M. 
34. Vol. i. p. 194. 49° 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° genre. Ilotes rotalitatus. A bad copy of 
Fichtel and Moll’s figure of Orbiculina Orbiculus. 
36. Vol. i. p. 202. 51° genre. Themeon rigatus. This is the 
. common Polystomella crispa, Linn. 
37. Vol. i. p. 206. 52° genre. Cellanthus craticulatus. Badly 
copied from Fichtel and Moll’s figure of Polystomella craticu- 
lata. 
38. Vol.i. p.210. 53¢ 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 Nonionine are weak 
varieties of Polystomella. 
39. Vol.i. p. 214. 54° genre. Robulus cultratus. Cristellaria 
Calcar, var.r, F.& M. One of the most common of the whole- 
keeled Nautiloid Cristellarie. 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° genre. Patrocles querelans. Fichtel 
and Moll’s var. 7 of Cristellaria Calcar is here intended. 
41. Vol. i. p. 222. 56° genre. Spincterules costatus. This 
represents Cristellaria costata, F. & M. 
42. Vol. i. p. 226. 57* genre. Clisiphontes Calcar. This is 
Fichtel and Moll’s var. a of Cristellaria Calcar. De Montfort, 
who gives Buffon’s ‘ Mollusq.’ (Sonnini) pl. 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° genre. Herion rostratus. Cristellaria 
Calcar, var. ¢, F. & M.
