THE PROTEOMYXA 



(III.) Dictyomyxa, Monticelli, is like the preceding genus, but with 

 colourless pseudopodia. On Chaetomorpha crassa at Naples. 



Boderia, Wright (Fig. 9), is marine, orange or brown in colour, with 

 a membranous investment (?), from openings in which protrude three to 

 four long branching pseudopodia. The nucleus or nuclei after a time

Fio. 8. 



A, Colpodella pugnax. Three individuals attacking a Chlamydomonad. B, flagellate 

 zoospore of Pseudospora purasitica ; n, nucleus ; v, vacuoles, said to be contractile. C, the 

 amoeboid phase of Pseudospora which succeeds the Actinophrys stage ; s is probably a mass of 

 ingested starch-grains. L), Gymnophrys cometu. B, Nudearia delicatula with three nuclei, n. 

 F, Arachnula impatieii-s. G, Aciinophrys stage of Ciliophrys ; n, nucleus. H, flagellate 

 stage of Ciliophrys infusionum ; c.v, contractile vacuole ; n, nucleus. (All after Cienkowski.) 



disappear, and the protoplasm spreads out in ragged masses on the slides, 

 A number of naviculoid bodies are formed, from each of which a small! 

 amoebula emerges in a few days. Marine. 1-4 mm. 



GROUP D. 



Most of the genera included in this group form plasmodia, and their 

 affinities seem to be with the Mycetozoa. No plasmodium-formation has 

 been found in Aphelidium, Colpodella, Pseudosporidium^ and Pseudamphi-
