ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 683- 



In regard to the vexed question of terminology, the author believes 

 that there are three clearly defined malarial parasites which occur in 

 man, — Plasmodium malarise (Laveran), the parasite of Quartana ; P. vivax 

 (Grassi et Feletti), the parasite of Tertiana; P. prsecox (Grassi et 

 Feletti), the parasite of Perniciosa ; and that the generic name Plas- 

 modium must stand. The Proteosoma of birds appears to be identical 

 with Plasmodium prsecox, but the position, of Malteridium remains 

 uncertain.
