Protozoa Incertæ Sedis

Sergentella hominis, Brumpt, 1910.

Et. and Ed. Sergent in 1908 found vermiform bodies about 40 µ long by 1 µ to 1·5 µ broad in the blood of an Algerian suffering from nausea and cold sweats, without other symptoms. The bodies were pointed at each end, with a somewhat ill-defined nucleus in the middle. Their systematic position is doubtful.

Note.—An Appendix on Protozoology will be found on pp. –752. This has been prepared in order to incorporate a number of new additions to knowledge made since the body of the book was printed off.
