PLATE 26. 
Fig.1. Myzxobolus sp. 52. Section of a pigment follicle of the walls of the splenic 
artery; after slight pressure the pigment globules are seen showing untailed 
spores (after Remak. x1). x 200. 
Fig. 2. Myxobolus sp. 53 (after Rayer. 1). Vertical views of spores. 
Figs. 3-6. Myzxobolus oblongus. 
3. Branchize with cysts (after Miiller. x 1). 
4, Individual lamelle with cysts (after Miiller. x1). 
5. Spores (after Miiller. xX 1). 
5a. Vertical view. 
5b. Transverse view. 
6. Spores (original). 
6a. Broadest form, showing, in the sporoplasm, the central tongue-shaped 
dark-staining portion and the first and third series of nucleitorm bodies. 
Gentian violet; slightly diagrammatic. 
6b. More elongate form, showing the tongue-like process and the second and 
third series of nucleiform bodies. Gentian violet; somewhat diagrammatic. 
6c. Narrower form, showing the first and second series of nucleiform bodies. 
Hydrochloric acid alcohol carmine. 
6d. Narrow form, showing the 3 series of nucleiform bodies and posteriorly an 
unusual appearance. Hydrochloric acid alcohol carmine. 
6e. Transverse view of spore, showing equality of valves and relative width of 
ridge (ridge index). 
Figs. 7-8. Myxobolus lintoni (original). Vertical views of 2 spores, showing cap- 
sules and sporoplasm, the latter with vacuole and 4 nuclei (2 of them the 
pericornual). Hydrochloric acid alcohol carmine. 
PLATE 27. 
Myzxobolus lintonit (after Linton. x 1). Nos, 2-13, highly magnified. 
1. Cyprinodon variegatus, with excrescences caused by this species; one on 
right side, and another on left side showing above outline of back. X 1}. 
2-3. Spores showing the pericornual nuclei. In fig. 3 there are a few small 
refractile globular masses near the posterior end. 
4. Spore treated with osmic acid, showing mouths of the ducts. 
5-6. Spores in transverse view, showing the ridge. 
7. Spore treated with acetic acid, showing vacuole (exaggerated). 
8. Diagram of cross-section, showing lenticular shape of spore. 
9-11. Specimens treated with concentrated sulphuric acid. 
9. With a few refractile bodies and 1 filament extruded. 
10. Spore with both filaments extruded and a number of small refractile glob- 
ules. 
11. Spore with sporoplasm ‘‘contracted” [? shrunken by reagents]; ‘‘a thread 
also appears at the end opposite the polar vesicles.” 
12-13. Free capsules and filaments, after treatment with concentrated sulphuric 
acid. 
14. Caleareous bodies found in the abnormal tissue, associated with the WM. 
lintoni. X 200. 
15. Three of the same, with afew spores. Sketch from material after action of 
potassic hydrate. x 400. ’ 
16. Spores in situ: (a) nests of spores; (b) section of blood capillary; (¢) con- 
nective tissue. Sketch made from a section of decalcified abnormal tissue. 
PLATE 28. 
Figs. 1-3. Myrobolus globosus (original). 
la. Vertical view of spore, showing capsules and sporoplasm, the latter con- 
taining a vacuole and 4 nuclei, 2 of them being the pericornual. 
1b. Transverse view of spore, showing the equal convexity of the valves and 
the wide ridge. 
2,3. Vertical views of spores exhibiting the same features as fig. la. 
Fig. 4. Myzxobolus sp. 56 (original). Vertical views of spores, showing capsules 
and sporoplasm, the latter with the vacuole.
