594 THE INFUSORIA. 
The Order Radiolaria embraces some very beautiful forms, radiated and resembling 
crystals of snow-flakes. 
The Order Reticularia includes the Horaminifera such as are figured above, Polystomella, 
Bulina, ete. One of the most notable of these is the Globigerina, a wonderful little micro- 
scopic globe, from which radiate myriads of spine-like organs, nS the creature a resem- 
blance to some of the Hchini. The celebrated ‘‘ Globigerina ooze,’’ described by the naturalists 
of the ‘‘ Challenger,’’ is made up of this little animal in innumerable numbers, forming vast 
beds of mud on the ocean bottom. : 
The Class Iyrusorta includes certain more familiar forms called Vorticella and Stentor, 
etc. But the most notable is the WVoctiluca, the largest of all, being visible to the naked eye. 
This is somewhat like a gooseberry in aspect. It is noted for its beautiful phosphorescence— 
the sea at times being wonderfully illuminated by myriads of it on the surface. It has been 
seen in this condition on the Coast of Maine and Massachusetts. 
Many species of these ‘‘ animalcules”’ exist, and many of their forms are as fantastic and 
beautiful as anything Nature produces.
