ix. 1884, p. 517, pi. lxv. figs. 16, 17. — One specimen from Hunstanton 
(Sherborn), now in the Geological Collection, Science Schools, South 
Kensington. Beuss figured this foraminifer from the chalk of Bohemia 
under the name of L. bohemica (Verst, bohm. Kreide, part 2, 1846, 
p. 108, plate viil. (xliii.) fig. 10) and also as L. nodosaria from the 
Speeton clay of Spectsbrink (SB. k. Ak. Wiss. Wien, xlvi. 1862, 
p. 59, plate v. fig. 12). We have also seen it in a slice of red gault 
from Hersingham lent to us by Mr. W. Hill, F.G.S. 
Frondicularia Defiance, 1824. 1 
Frondicnlaria biformis Marsson, plate X. fig. 4. Marsson,

F. Archiaciana d’Orb., plate X. figs. 6 a, b. D’Orbigny, Mem. 
Soc. Geol. France, iv. 1840, p. 20, plate i. figs. 31-36. — We regard 
this as referable to d’Orbigny ’s form. Beuss figured it from the chalk 
of Bohemia under the name of F. bicuspidata (Verst, bohm. Kreide, 
part 1, 1845, p. 32, plate xiii. fig. 46), a varietal form, with which our 
specimens closely agree. Dimikowski’s F.polonica (Kosmos [Lwow], 
iv. 1879, p. 124, plate, fig. 16), from the chalk of Lemberg, belongs 
also to d’Orbigny’s species.
