Injury to Host.—The Filaria Papillosa are common 
in horses in the United States, but are found only in 
small numbers and do not produce serious results. 
If found in large numbers they may cause anemia, 
debility and death. This filaria while in the imma- 
ture state may find its way to the eye, and the worm 
can then be seen floating in the aqueous humor. By 
opening the anterior chamber the worm can be taken 
from the eye. The name, Filaria Oculi, or Filaria 
Oculi Equina, has been given to this worm when 
found in this locality. When the worm finds its way 
‘ to the eye it may cause inflammation, swelling of the 
eye andclosure of the lid. The cornea may become 
opaque.
