Coecidia with Ciliated Microgametes.* — M. Louis Leger previously 
observed the occurrence of locomotor cilia in the microgametes of Bar- 
roussia caudata , and he has found them also in Ecliinosjpora ventricosa 
sp. n. from the alimentary canal of Lithobius liexodus. 
Hsematozoa of Beri-Beri.f — Dr. F. Fajardo states that he has found 
in the blood of persons suffering from Beri-Beri, a hasmatozoon which 
forms spores, produces pigment, and whose developmental phases have a 
close resemblance to those of the malaria parasite. The lisematozoon 
exists chiefly in the red corpuscles, but is also observed free in the 
plasma. It is a more or less spheroidal mass of protoplasm, which at 
first is devoid of pigment, but afterwards contains pigment granules. 
These granules arc of variable colour, ranging from yellow and red to 
black, and are also of variable size and number. Sometimes vacuoles 
may be observed in the parasites.
