FOSSIL RHIZOPODA, FLAGBLLATA, MONADS. Prot. 12 
Stoliczicaria, id. tom. cit. p. 299. As preceding, but with very fine sur- 
face pores, or none at all, and close internal tubulation. 
Stromatocerium, Hall, emended, (14) p. 222. 
Bradyina, Von Moller, (13) p. 78, pis. iii. figs. 3 & 4, x. figs. 2 & 3. 
Based on Nonionina rotula, Eichwald, &c. Shell unsymmetrical ; differs 
from HemifusuUna., V. Moll., in the distinct and entire canals of the 
septa. Carboniferous limestone of Russia, &c. 
Crihrospira, Yon Moller (13) p. 86, pis. iv. fig. 1, x. fig. 1. Shell 
asymmetrical, septa small, unilamellar, chambers simple ; otherwise agrees 
mainly with Brady ina. Contains one sp. n. from lower carboniferous 
limestone, Russia. 
. A special family, FusulinidcB^ established (13, p* 120) to include Num- 
muUna^ Fusulina, Schwagerina, Hemifusulina. 
The StromatoporidcB were (14) originally calcareous. No canal sys- 
tem,” like that of the Foraminifera^ exists in the walls, which are, how- 
ever, traversed by “ water canals ” (radiate and vertical) \ apparently 
should be placed among the Calcisponges. 
Stromatopora, Goldfuss, spp., (14) p. 217, and Caunopora, Phillips, 
figured.
