Leucosolenia botryoides Bowerb. is an aggregation of new furms of Mor 
closely allied to Monas termo Ehren. The existence of a mouth at 
base of the flagellum, a lash-like organ present in many infusoria, is 
monstrated in all these forms, and all except Monas are described as 
sessing a hyaline calyx, or cup, surrounding the region of the mouth, 
an inverted funnel. The single monads which compose the ciliated 1 
lining the internal channels of Leucosolenia, a common marine spo 
have a similar calyx, are monoflagellate (that is, provided with a si 
lash-like appendage), and probably have a mouth at the base of the 
lum, since they took in their food in the same manner as the Monas te 
The connection between Monas and its allied forms, with the higher}

by Anthophysa Mulleri which has two flagella, like the higher forms 
tioned, but like Monas has no calyx, and grows in umbellate colonies
