SUMMARY OF CURRENT RESEARCHES RELATING TO 
Protozoa. 
Foraminifera from Chalk of Taplow.* — In a report on the Microzoa 
from the Phosphatic Chalk of Taplow, Mr. F. Chapman enumerates 
ninety-eight species of Foraminifera, five of which are new to science, 
while thirty are new to the Chalk fauna ; of these last two were hither- 
to known only from recent deposits. 
Notes on Coccidia-t — MM. A. Bailliet and A. Lucet have been 
engaged in the study of the Coccidia of some of the domestic animals. 
Coccidium perforans appears to be almost confined to the intestine of 
Man and the Babbit ; C. tenellum sp. n. is found in the Chicken, and 
probably also in the Pigeon, Goose, and Duck, and seems to be limited 
to the intestine. C. truncatum sp. n. has been found in the kidneys of 
the domestic Goose, where it is expelled into the urine. G. bigeminum , 
lately described by Stiles, but detected many years before by Finck, 
exists under three, if not four, varieties. 
Sarcosporidia and Parasitic Sacs in Body-cavity of Rotifers.:]: — 
Dr. Bertram describes Sarcocystis platydactili sp. n. in the muscle-fibres 
of the Gecko, S. miescJieri Bay Lankester, S. tenella Baill, and Balbiania 
gigantea Baill. He also describes microscopic parasites found (in 
September and October) within the body-cavity of three species of 
Brachionus. They appear to resemble zoosporangia of Chytridium.
