In a gatheiing of a miscellaneous character from a small piece 

 of swampy ground, I came across a number of specimens of a 

 Rhizopod, which can only, I think, be identified as above, cf. 

 Cash, Brit. Frw. Rhiz., i., PI. xiv., f.l. Our specimens agree 

 with his figure, but not too well wii,h the descripticm. The cysts 

 were apparently of a tough, mucous nature, pale yellow, of 

 irregular shape and large size. The plasma, which entirely filled 

 the capsule and protruded slightly beyond it, was of a dark 

 purple colour from the presence of quantities of minute purple 

 granules. None of the creatures were active, save for a few 

 sluggish, amoeboid movements. The cysts seemed to have been 

 pedunculate. 



Length of cyst 120-280, breadth 130-140/x.

Genus C y s t a M ce b a, gen.nov. 

 Cystamo-^ba digitata, gen.nov. et sp. 



Living creature of an amoeboid nature, 

 inhabiting an oval, chitinous, thick-walled 

 cyst. The cyst is perforated by small 

 foramina, through which the animal pro- 

 trudes short, blunt, digitate pseudopodia. 

 Plasma hyaline, refractive, reminiscent 

 of Dactyl()sph(criurn radiosutn {Amoeba 

 radiosa). 



Length of cyst 20, breadth 1 6,pseudopod. 

 about 10 long, 1J-2/X broad. 



Lismore (233).
