MASTIGOPHORA AND PROTOMONADINA 



Prowazekia cruzi Hartmann and Chagas, 1910. 

 Oval to pear-shaped forms; length 8 to 12 /a; breadth, 5 to 6 ^, 

 with the flagella at the narrow end. Found in Brazil. Differs 

 from P. asiatica by the absence of the strand which originates from 

 the kinetonucleus and terminates into a chromatin granule. Martin 

 has found in human stools in Tsingtau a Prowazekia which he 

 believes to be identical with P. cruzi. 



Prowazekia weinbergi Mathis and Leger, 1910. 

 Pear-shaped, but rather drawn out into a point; length, 8 to 15 ^; 

 breadth, 4 to 6-5 ^jb. Flagella at broad end. Found frequently in 

 the motions of men in Tonkin. 



Prowazekia parva Naegler, 1910. 

 Characterized by its small size, the longest forms being 5 to 8 

 The cysts do not contain flagella. 



Prowazekia javanensis Flu, 1912. 



Definition.— Prowazekia in which the posterior flagellum is 

 attached to the body for a short distance. 



Remarks.— Flu believes that there is only one species of Prowa- 

 zekia. He obtained his variety from an agar culture of human 

 faeces in the Dutch East Indies. 



Prowazekia vaginalis Castellani and Chalmers, 1918. 



Definition. — Prowazekia living in the vaginal mucus. 



Remarks.^ — Morphologically identical with P. asiatica found in 



motions, but the investigated strains of the latter will not live in 



vaginal mucus. ^ « j • o

Definition.— Bodonidae without undulating membrane or kineto- 

 nucleus, but with a rhizoplast. While swimming one flagellum is

 19 long and is from 6 //, to 9 /x broad, with large nucleus.

 A flagellate organism semilunar in shape, 6-9-6 x i -6-4-8 microns, 

 found in the human intestine and grown for ten generations in 

 culture media (peptone water). It has two flagella, and resembles 

 a Bodo, except in shape.
