This parasite was identified by me from material collected 

 by Dr. Oleland on the Shaw River in the north-west of 

 West Australia. Their position was remarkable, the worms 

 being embedded in the subcutaneous tissues and in the 

 superficial muscles, reminding one of the Trematode Mono- 

 slumutn [iiha, Bremser, which lives in a similar situation 

 in many passerine birds in Europe.
