94, BRITISH FRESHWATER RHIZOPODA, 
yellow colouring matter, make it seem rather refer- 
able to the alge, a view greatly. strengthened by the 
existence of a Protococcus stage, . . . it would thus 
take a place among the lower alge 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 alge, 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 alge. His 
theory of this organism and its relationship was, how- 
ever, ridiculed by Professor Lankester in a foot-note 
to the translation cited. 
Family 3.  VAMPYRELLIDA. 
Naked rhizopods with amoeboid movenients ; pseudo- 
podia variable, sometimes radiate, simulating those of 
the Heliozoa. Nuclei mostly obscure; in some species 
unknown. 
SYNOPSIS OF THE GENERA. 
Plasma-body soft, granular, reddish, variable in 
outline, sometimes spherical or sub- -spherical, with 
radiating pseudopodia. 11. Vompyretla.
