The cysts of .this protozoan were found imbedded in the 

 posterior region of the brain of the Angler fish [Lophius 

 piscatorius) forming a conspicuous mass, easily visible to 

 the naked eye when the brain had been dissected out. 

 Very much larger masses of cysts were found surround- 

 ing the main trunks of the seventh nerve just outside the 

 skull. The fish measured about two feet in length, and 

 was caught on the offshore station between Lancashire 

 and the Isle-of-Man, April 19th, 1901. Mrazek obtained 

 his specimens from Lophius caught at Triest and Naples.
