331] STUDIES ON MYXOSPORJDIA—KUDO 93 



CHLOROMYXUM FUNDULI Hahn 

 [Figs. 139 and 140] 



1915 Chloromyxum funduli Hahn 1915:205-206 



Habitat: Muscle of Fundulus sp.; Woods Hole. In one fish. 



Vegetative form: Hahn made observations on few fresh and stained 

 smears. According to him, it is clear that the staining was abnormal. 

 It is hard to quote this here as he used different terms without giving any 

 definition. The reader is advised to consult Hahn's paper. 



Spore: Form slightly resembles that of Choloromyxum quadratum. 

 Posterior end rounded, the anterior portion narrow and truncated at the 

 tip; optical cross-section thru the posterior part of the polar capsules, 

 circular. Four polar capsules at the anterior end. Dimensions: height 

 (length) 6)u, breadth and thiclcness 7.5^ respectively. 



Remarlis: As to the comparison of the present species with Chloro- 

 myxum clupeidae Hahn, see p. 94. 



CHLOROMYXUM MISGURNI Kudo 

 [Figs. 141 to 146] 



1916 Chloromyxum tnisgurni Kudo 1916 : 6-7 



Habitat: Gall-bladder of Misgurnus anguillicaudatus Cantor; Tokio 

 (September). 



Vegetative form: Round or irregular. Semicircular when viewed from 

 side. From the flat surface, many fine root-like, filiform pseudopodia are 

 extruded. No clear differentiation between ectoplasm and endoplasm. 

 Endoplasm alveolar. Trophozoites always found attached to the lining 

 epithelial cells. Size up to 50/x by 20/i. Polysporous (6 to 8 spores), rarely 

 disporous. 



Spore: Spherical, slightly attenuated at the anterior end. Sutural line 

 straight and forms a ridge. Fine longitudinal striations run parallel to 

 the sutural line. Four polar capsules at the anterior end. Sporoplasm 

 finely granular, has two nuclei of equal size. Dimensions: length 8 to 

 9)u, breadth 6 to 7/x, thickness 5 to 6^, length of polar capsule 2 to 3ai, 

 of polar filament 28 to 35m (KOH). 



Remarks : The host is often infected at the same time by Chloromyxum 

 fujitai, the trophozoites of which can be distinguished from the present 

 form by the structure and the floating habit in the bile. Spores in the 

 two species are decidedly different in form, structure and size. 



CHLOROMYXUM FUJITAI Kudo 

 [Figs. 147 to 152] 

 1916 Chloromyxum fujitai Kudo 1916:7-9 



Habitat: Gall-bladder of Misgurnus anguillicaudatus Cant.; Tokio, 

 (5% of the fish examined in September, found infected).
