Nucleus as in the preceding species.

Not common; occasionally met with in’ pools and 
sphagnum bogs. 
The peculiar hernia-like pseudopodia, and the broad 
frontal expansions of the ectoplasm, are characters 
which seem to justify the separation of this from the 
preceding and other allied species. The pseudopodium, 
emanating from the surface of the body, resembles a 
miniature eruption. Through the breach made, the 
granular endoplasm, in its flow, recoils on either side 
upon the spherical body, instead of forming a digitate 
prolongation.
