Since then new inoculable piroplasmata of the type Piroplasma 

 parvum had been described by Theiler and called Piroplasma mutans * 

 and by Miyajima and Shibayama in Japan,t which led Bettencourt to 

 suggest the following classification, viz. : — 



1st Group. — Piroplasmoses produced by parasites presenting in one 

 of their evolution phases the form of a pear and disposing 

 themselves in pairs in the same corpuscle. 

 Babesia bovis (Babes). 

 Babesia bigeminum (Smith and Kilborne). 

 Geographical distribution, Europe, America, Africa. 

 Ind Group. — Piroplasmosis produced by parasites presenting always 

 at one phase of their evolution the form bacillary — Piro- 

 plasmoses bacilliformes . 



(a) Piroplasmoses bacilliformes, inoculable. 



Babesia annulata {Piroplasma annulatum) Dschunkowsky. 

 Babesia mutans {Piroplasma mutans) Theiler. 

 Babesia bacilliforms found amongst the cattle of Japan 

 (Mivajima and Shibayama). 



Geographical distribution. — Transcaucasia, Japan, South 

 Africa, to which may be added the following, viz. : — Piro- 

 plasmosis, described bv Stephens and Christopher, in Madras ; 

 Shein in Annam;j Bettencourt in Portugal ;§ Boeret on the 

 G-old Coast of Africa ;|| Does in the Dutch Indies ;T[ Martini 

 in Peycheles, China;** Lichtenheld in Grerman East Africa ;f"]" 

 Balfour in the Soudan ;JJ Broden and Rodhain, Congo (Stanley

(&) Piroplasmoses bacilliformes, non-inoculable. 



Babesia para\\\\ {Piroplasma. parvum) Theiler. 



Babesia of Tunis and Egypt.
