Carpenter, W. B., & Brady, H. B. Description of Parkeria 
and Loftusia, two gigantic types of arenaceous forami- 
nifera. Monthly Mic. Journal, May 1869, pp. 299-304; 
also Ann. & Mag. Nat. Hist. ser. 4, vol. iii. June 1869, 
pp. 460-464; and Phil. Trans. 1869, pp. 721-754, plates 
72-80. 
Pai'keria is from the Upper Greensand near Cambridge, and 
Loftusia from a tertiary limestone found near Ispahan, in the 
Persian Gulf; but they are too intimately associated with 
recent forms not to be alluded to here. 
Carter, H. J. Description of a siliceous Sand-sponge found 
on the south-east coast of Arabia; Ann. & Mag. Nat. Hist, 
ser. 4, vol. iii. January 1869, pp. 1517 (woodcut). 
. Notes on Filigerous green Infusoria of the Island of 
Bombay. Ibid. April 1869, pp. 249-260, pi. 17. 
. A descriptive account of four Subspherous Sponges, 
Arabian and British, with general observations. Ibid, 
vol. iv. July 1869, pp. 1-28, pis. 1 & 2. 
. On Graydla cyathophora, a new genus and species of 
Sponge. Ibid. vol. iv. September 1869, pp. 189-197, pi. 7. 
Czerny, V. Einige Beobachtungen iiber Amoeben. Schnitzels 
Archiv f. mikrosk. Anat. Bd. v. pp. 158-163. 
Treats of the different behaviours of Amoebae under different 
reagents. Giant forms of Amceba princeps found on frog-spawn 
&c. taken from the Danube Canal, were treated to muriatic 
acid ; and the author seems to be of opinion that the cilia of 
Infusoria are but a modified protoplasm, or rather a sort of con- 
stant pscudopod, differentiated and modified as we see partially 
in ciliated epithelium. 
Gray, J. E. On the manner of growth of Hyalonema. Ann. 
& Mag. Nat. Hist. iii. 1869, pp. 192-196. 
Contains a letter from Professor Loven, with a woodcut 
showing the presumed mode of growth of Hyalonema. 
4 Note on lanthellaj a new genus of Keratose Sponges. 
Proc. Zool. Soc. 1869, pp. 49-51. 
Greefp, R. Ueber Radiolarien und Radiolarien-artige Rhizo- 
poden des sussen Wassers. Schnitzels Archiv f. mikroskop. 
Anat. Bd. v. 1869, October, pp. 464-505, Taf. 26, 27. 
Many new forms, described more particularly in the special 
part, are here recorded. 
Grenacher, H. Bemerkungen iiber Acanthocystis viridis, 
Ehbg. sp. Zeitschr. f. wissensch. Zoologie, xix. Bd. 2 Heft,
