CHLAMYDOMYXA LABYRINTHULOIDUS. 93 
Dimensions of cist variable. 
Parasitic on Sphagnum in bogs, County Westmeath 
(IW. Archer). 
Mr. Archer, who discovered this singular organism, 
and whose description of it we have condensed, says 
that the test, or coat, which encloses the protoplasmic 
body, is composed of several layers of the same kind of 
material, has an irregular outline, and is often very 
thick, according to the number of lamina. It is tough, 
and requires strong pressure of the covering-glass to 
burst it. The outer figure is variable in form, and 
often presents neck-like extensions of greater or less 
width, terminating in a lacerated orifice. 
The presence of Chlamydomyra in quantity, in the 
bogs of Connemara, was revealed by the reddish colour 
of the Sphagiuwm, which held the organism in the 
encisted condition. Itis this colour which first attracts 
attention under the microscope. When encisted and 
completely dormant the cellulose envelope appears 
densely filled with the granular substance. 
Mr. Archer found that in spite of the seemingly 
tough consistence of the envelope, it was capable of 
being burst by the organic substance which escaped 
and entered upon a period of amceboid activity. The 
protoplasmic body is without any hyaline border, and 
the hyaline branching filaments extend and ramify im 
an extraordinary manner. They are flexible, but 
while not seen to alter much in position, they grow in 
length and in number. Part passw with their appear- 
ance there occur at various distances upon their sur- 
face the minute fusiform bodies (“spindles”) previously 
referred to, which glide along very slowly. 
Professor Geddes (loc. cit.) discusses the affinities of 
Chlamydomyva and its systematic position. The semi- 
amoeboid character of the organism in its resting state, 
and its exalted amceboid activity when motile, might, 
he says, tempt one rather to refer it to the Thala- 
mophora. “Its cellulose wall, its red, green, and
