86 BRITISH FRESHWATER RHIZOPODA. 
Body extensile, its contour during activity very 
variable; the pseudopodia anastomosing and forming 
an extended net-work of fine protoplasmic threads. 
9. Penardia. 
Protoplasm hyaline, granular, containing, besides 
numerous small pulsating vacuoles, a mass of rounded 
or fusiform pale-bluish corpuscles, which travel simply 
up and down the delicate, widely-spreading pseudopodal 
filaments. Body in the resting state enclosed in a 
toughish cellulose cyst which is formed in the leaf- 
cells of Sphagnum and other sub-aquatic plants, and 
from which the organism escapes at maturity. 
10. Chlanydomyea. 
Genus 7. GYMNOPHRYS Cienkowski, 1876. 
Gymnophrys Crenxowsxt in Arch. f. Mikr. Anat. XII 
(1876), p. 31, 
Body persistently sub-spherical or ovoid, changing 
little in general contour; the endoplasm colourless 
(containing sometimes a few greenish particles), and 
emitting at various points fine elongated anastomosing 
and widely-spreading pseudopodia, in which is a per- 
ceptible granular current. No nucleus visible. 
The small sub-spherical or oval body, from which 
spring widely-extending, geniculate, and extremely 
attenuated pseudopodia (few in number and many 
times longer than the body-diameter), sufficiently sepa- 
rate this genus from Bionyera, although it agrees with 
that genus in the character of the endoplasm. In 
PBiowmyeu the body is more elongated, and branched, 
and the pseudopodia form a closer network.
