329] STUDIES ON MYXOSPORIDIA—KUDO 91 



CHLOROMYXUM CRISTATUM Leger 



[Figs. 127 and 128] 

 1906 Ckloromyxum cristakim Leger 1906 : 270-272 



Habitat: Gall-bladder of Tinea vulgaris Cuv.; Grenoble. 



Vegetative form: Ordinarily massive, with oval or round contours, 

 without noticeable pseudopodium. Ectoplasm hyaUne. Endoplasm 

 granular and colorless. Average diameter of the adults about 20/x. Mono- 

 sporous, rarely disporous. 



Spore: Spherical or subspherical. Ten marked ridges run antero- 

 posteriorly on each shell- valve, so that it presents a cog-wheel form in cross 

 section. Four polar capsules at the anterior end, one pair being smaller 

 than the other. Sporoplasm with two nuclei. Dimension: 10 to ll/z. 



CHLOROMYXUM DUBIUM Auerbach 



[Figs. 129 to 133] 



1908 Chloromyxum dubium Auerbach 1908 : 456-459 



1910 Chloromyxum dubium Auerbach 1910c : 177 



Habitat: Gall-bladder of Lota vulgaris Cuv.; Bodensee (April to Sep- 

 tember). 



Vegetative form: Spherical or rounded. Rarely irregular forms. 

 Protoplasm is differentiated distinctly into ectoplasm and endoplasm. 

 Ectoplasm very thin, forms pseudopodia which move slowly. Endoplasm 

 granular, contains fat globules. Majority of the trophozoites appear to 

 live floating in the bile, while some are attached to the epithelium of the 

 bladder. Disporous and polysporous. 



Spore: Spherical, with four polar capsules. Each shell valve has 

 longitudinal ridges, variable in number (6 ridges are found on the drawing), 

 which run parallel to the sutural line. Four polar capsules of nearly same 

 size and convergent. Sporoplasm finely granular with two nuclei. Dimen- 

 sions: diameter 10. S/jl, length of polar capsule 3.6^. 



CHLOROMYXUM sp. Awerinzew 

 [Fig. 134] 

 1908 Chloromyxum sp. Awerinzew 1908 : 43, 47, 48 



Habitat: Gall-bladder of Raja radiata; Murman coast?. 



Vegetative form: Form rounded. The protoplasm is distinctly differ- 

 entiated into ectoplasm and endoplasm. Ectoplasm hyaline and compara- 

 tively abundant in quantity compared with endoplasm, forms lobose 

 pseudopodia of active movements. Endoplasm vacuolated, contains 

 enclosures. Between the two layers, a thin layer of protoplasm, reticular in 

 structure and stained deeply with hematoxylin, is present. 



Spore: No figure.
