Origin of Haemoflagellata in Vertebrates.* — E. Brumpt main- 

 tains that the presence of Hajnioflagellata found in Vertebrates are due 

 to accidental intrusions of common intestinal parasites of Inverte- 

 brates — e.g., of the leech.

 inoculation experiments by which he has been able to corroborate his 

 previous conclusion that Trypanosoma pecaudi, T. dimorphon, and T. 

 congohnse are quite distinct species.
