86 BRITISH FRESHWATER KHIZOPODA. 



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.

Genus 7. GYMNOPHRYS Cienkowski, 1876. 



Gymnophrys CIENKOWSKI 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 r 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 Biomyxa, although it agrees with 

 that genus in the character of the endoplasm. In 

 THomyxa the body is more elongated, and branched, 

 and the pseudopodia form a closer network.
