Protoplasm finely granular, colourless, or presenting 
a faint greenish tinge from the presence of chloro- 
phyllous particles; the body persistently sub-spherical 
or irregularly elliptic, with no apparent nucleus or” 
contractile vesicle; subject to few changes super- 
ficially, but emitting at from two or more points fine, 
mostly elongated and diverging—never crowded— 
pseudopodia, which branch out into fine filaments and 
anastomose. The pseudopodia are of irregular thick- 
ness, swollen at intervals, and granular throughout, 
the granules exhibiting a circulatory movement. Pseu- 
dopodia are occasionally formed, which do not attain 
the average length, and possess considerable mobility. 
The longer and finer ones are very inactive, and some- 
times remain stationary for long periods; they may be 
straight, bent at a sharp angle, branched, or elongated 
and curved, sometimes measuring in length six to ten 
times the diameter of the body. 
Dimensions: Average diameter of body 35-40 p, 
sometimes 80, or more; length of the pseudopodia 
anything up to 400 p, or even longer. 
In Sphagnum, Lindow and Dunham, Cheshire; Car- 
narvonshire, N. Wales. Near Brigg, Lincolnshire (}’est). 
Cienkowski describes Gymnophrys cometa as a 
moneron, whose anastomosing pseudopodia, possessing 
a distinct granular current, are confined to a few 
points only of the body-surface—not regularly dis- 
tributed over it. Except that the pseudopodia appear 
somewhat more numerous, in adult individuals, the 
Cheshire examples agree well with this author’s de- 
scription. They vary in size. Not infrequently small
