- 980 General Notes. (September, 
Prehensile flagella, often striated transversely, as though made 
by the union of corpuscles placed end to end, occur in the Fla- 
gellata. They can be seen in every individual that has been long 
submitted to energetic coloring reactives, and are always situated 
on the border of the upper lip. These buccal flagella are shorter 
than the locomotive flagella, since they are never longer than the 
body, while the filaments before mentioned may attain twelve 
times the body length. Chilomonas paramecium and some other 
species, when in more or less putrified cultures, or in a bad light, 
become united into a zodglea-like mass.
