Family 1 Polyblepharidae Dangeard 



Flagella are four or more in number. Lacking a cellulose 

 membrane, the body form changes to a certain extent. Found 

 mostly in salt water. Common genera are as follows: 



Genus Pyramimonas Schmarda ( = Pyramidomonas Stein). 

 Small pyramidal or heart-shaped body; with bluntly drawn-out 

 posterior end. There are usually four ridges in the anterior 

 region. Four flagella; green chromatophores cup-shaped; with 

 or without stigma; with a large pyrenoid in the posterior part. 

 Contractile vacuoles in the anterior portion. Fresh water.
