a. Archer. — Chlamydomyxa labyrinthuloides was 

 originally discovered and named by Archer (1) in 1875. He 

 supposed it to be related to Labyrinthula (4)^ and described it 

 as a protoplasmic body, rounded or irregularly lobed, invested 

 by a cellulose cyst, colourless, or straw-yellow, and generally 

 of several layers, and living on water-plants, or parasitically in 

 the cells of Sphagnum or Eriophorum leaves, or in the air- 

 spaces of roots of Eriocaulon. He further saw it streaming 

 out through a rupture in the cyst as a sort of labyrinth-like 

 meshwork, the nodes of which were amoeboid, ingested Algae, 

 and finally encysted themselves anew.
