yellow colouring matter, make it seem rather refer- 

 able to the algge, a view greatly strengthened by the 

 existence of a Protococcus stage, ... it would thus 

 take a place among the lower alga3 which the 

 Myxomycetes do among the lower fungi." On the 

 whole this author is " inclined to regard it as a 

 degenerate form from the Palmellaceous algae, but one 

 sufficiently aberrant to take place alone, and form the 

 type of a new order, the Chlamydomyxida." In any 

 case, he considers it almost an ideal " Protist " which 

 cannot be distinctly appropriated by either botanist 

 or zoologist without a certain violence to the other." 



Hieronymus* held that, if not actually belonging to 

 the vegetable kingdom, C. labyrinthuloides was at any 

 rate on the border-land, but nearest to that kingdom 

 by reason of its chromatophores and cellular mem- 

 brane. He admitted that, in some of its phases, it was 

 certainly holozootic, but on a review of all the evidence 

 he came to the conclusion that it must occupy the 

 lowest place among the yellow-brown algae. His 

 theory of this organism and its relationship was, how- 

 ever, ridiculed by Professor Lankester in a foot-note 

 to the translation cited.
