showing outline, capsules (b with filaments extruded), and vertical position 
of ridge. 
Fig. 3. Chloromyxum sp. 91. Vertical (?) view of spore from the ovary of Lota lota 
— (after Biitschli. x $). Xx about 900. 
Figs. 4-7. Chloromyxum dujardini. 
4. From Leuciscus rutilus (after Miiller. X1).

4c. Transverse views. 
5. Myxosporidium from branchie of Leuciscus erythrophthalmus (after Dujardin. 
is) en icee 
6. Spore showing outline and capsules; from L. erythrophthalmus (after Dujar- 
Glin, 4 IDs Se ete 
7. Free ameeboid myxosporidium from a branchial lamella of Leuciscus erythroph- 
thalmus (atter Biitschli xX $3). X about 30. 
Fig. 8. Chloronyxum ohlmacheri (after Ohlmacher, Leitz obj. 3, 0c. 4. x1). From 
photomicrograph of section of kidney; showing at a, and elsewhere, myxo- 
sporidian masses in the tubules; at b extravasated blood corpuscles; at ca 
large blood vessel filled with blood corpuscles. Fuchsin and iodine green. 
PLaTE 41. 
Figs. 1-3. Chloromyxum ohlmacheri. 
1. Spores (after OhImacher. Leitz pantachromatic oflimm.2mm.,oc. 4. x1). 
la. Vertical view of spore, showing capsules with extruded filaments. Camera 
lucida; Babes’s anilin water safranin. 
1b. Vertical view showing capsules, spiral-coil structure of shell, and vertical 
position of ridge. 
le. Striew are seen ‘‘running nearly meridionally”; at one ‘“‘side” of spore a 
capsule ‘‘appears in the act of escaping through a rent” in the shell. 
1d. Fragment of shell in which the stri# appear to correspond to ridges 
encircling the shell. 
2. Kidney tubule, inclosing 3 spores, showing capsules and sporoplasm, the lat- 
ter structure being represented in 1 spore as divided into 2 lateral halves. 
(An error; see p. 270.) Pfitzner’s alcoholic safranin (after Oblmacher; 
camera lucida; Leitz pantachromatic 3 mm., oc. 4. 1). 
3. Diagrammatic figure of spore; a, shell; b, sporoplasm; c, capsule; d, posterior 
extremity of ridge and spore; e, ridge; jf, anterior extremity of ridge and 
spore; g, filaments, much shortened; a, b, c, are on the left side of spore; 
eon the right. (After Whinery. X 1). 
Fig. 4. Ceratomyxa spherulosa. Spore showing hollow-cone valves, vertical ridge, 
and valve-junction plane, capsules, and (spo.) the unilateral sporoplasm, 
and (x) pale corpuscles of indeterminate nature (after Thélohan. X #). 
PLATE 42. 
Figs. 1-10. Cystodiscus immersus (after Lutz. X 1). 
1. Gall bladder of Bufo aqua with myxosporidium disks shining through. X 1. 
2. Portion of mediura-sized specimen with large number of spores. X about 70. 
3. The same; the ruptured ectoplasm permitting the exit of the contents in the 
form of vesicles. X about 70. 
4, Ripe spore-pairs. 
5. Vertical (?) view of mature spores, showing ridge. 
6. Longitudinal (?) view of same. 
7. Spore with extruded filaments, showing the striw of the shell. 
8. Spore with valves separated. 
9. Developmental condition of spore. 
10. Mature spore; contents made plain by carmine; containing micrococcoid 
granules. x about 600. 
Figs. 11-13. Cystodiscus ?% diploxys (after Balbiani). 
11, 12. Spherical cysts in process of spore formation (X 1). x 85. 
13. Spores from the cysts (x #). X about 1500, 
13a. Vertical view. 
13b, c. Transverse views.
