454 INFUSORIA. 
Encuetis Mull., 
Where the body is oblong, softer, and less determined than that of a 
Vibrio. 
In Cycuipium it is flat and oval. 
In Paramecium it is flat and oblong. 
In Korpops it is flat and sinuous. 
In Gontvm it is flat and angular. 
And in Borsaris, hollow like a sac. 
The most singular genus of the whole is the 
Proteus, Lin. 
No determinate form can be assigned to them; their figure changes 
every instant, and is sometimes rounded, sometimes divided and sub- 
divided into thongs, in the most odd and singular manner *. 
Monas, Mull., 
The monades, viewed under the microscope, resemble points mov- 
ing with great rapidity, although destitute of any apparent organ of 
motion. 
VoLvox. 
A globular body revolving on its axis, and frequently containing 
smaller globules, which are doubtless the continuation of the race.

For other details concerning all these animals, see the posthumous work of Othon 
Frederick Miiller, entitled Animalcula Infusoria, the plates ef which have been 
copied in the Eneye. Méthodique. See also Rees., III, and for the classification, the 
work already quoted of M. Bory Saint Vincent. 
+ M. Audouin and M. Edwards, Ann. des Sc. Nat.; XI, pl., XVI, have adopted 
this opinion of M. Grant.
