during a feeding period. However, the account given by Hieronymus 
for the multinucleate encysted stage of C. labyrinthuloides agrees 
closely with that of Archer, and Hieronymus did once see a small 
specimen suspended in water with fine pseudopodia radiating in all 
directions ; hence the discrepancy between the two accounts of the 
free stage may he explained either by supposing that Hieronymus 
was examining a different species or a related genus, or that his

of organism in the free state, partially emerged from the lamellate cyst. B, 
cyst from hyaline leaf-cell of Sphagnum, constricted by the annular bands of the 
latter. C, part of a cyst, showing the chromatophores (shaded) and the 
phloroglucin granules (many of these arranged in chains), D, cyst with mature 
spores. E, early stage of spore formation—the cyst contents have divided up 
into young spores. F, spore, showing a nucleus at each pole, and numerous 
chromatophores. G, flagellula (gamete ?) emerged from a spore. A-C after

form may have been C. labyrinthuloides itself showing only early stages 
not previously observed, or this species may, like various other 
Proteomyxa (and other Protista), he polymorphic in its trophic or 
vegetative phase. After encystment the contents divide into 20 to 
40 portions (secondary cysts, or spores), which in C. montana, 
according to Penan! (1904), are binucleate and flagellate and may 
fuse in pairs. Penard suggests that Chlamydomyxa is related to the 
Mycetozoa, but its free stage cannot he regarded as a plasmodium, 
and from the facts available at present as to its life cycle it would 
appear better to place it among the lower Proteomyxa in the neigh¬ 
bourhood of Pseudospora, though its filose pseudopodia recall 
Mikrogromia and the lower Foraminifera, while in having numerous 
nuclei it resembles some of the Lobose Rhizopods like Trichosphcer- 
ium as well as the Sporozoa. On the other hand, should more 
critical investigation establish the non-symbiotic nature of the 
chromatophores, the genus might well be regarded as related to the 
Brown Flagellata, some of which show amoeboid trophic phases.
