4. Individual lamella; with cysts (after Miiller. X 1)» 



5. Spores (after Miiller. X 1). 

 5rt. Vertical view. 



5b. Transverse view. 



6. Spores (original). 



6a. Broadest form, sliowing, in the sporoplasm, the central tongne-shaped 

 dark-staining portion and the first and third series of nucleiform bodies. 

 Gentian violet; slightly diagrammatic. 



6&. 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 fir-t 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. Hyrlrochloric acid alcohol carmine. 



6e. Transverse view of spore, showing equality of valves and relati\'e width of 

 riflge (ridge index). 

 Figs. 7-8. MifroholnH liiifoni (original). Vertical views of 2 spores, showing cap- 

 sules and sporo])lasin, the latter with vacuole and 4 nuclei (2 of them the 

 pericoruual). Hydrochloric acid alcohol carmine. 



Plate 27. 



Mi/xobohis Uniovi (after Linton. X 1). Nos. 2-13, highly magnified. 



1. Cii/innodoii rufi<'<i>ifi:x, with excrescences cansefl by this species; one on 



rijilit side, and another on left side showing above outline of back. X 1^. 

 2-3. Spores showinu,- the pericornnal un(dei. In fig. 3 there are a few small 



retractile (ilohnlar masses near the posterit)r end. 

 4. Spore treated with osniic acid, showinj;- months of the ducts. 

 5-6. S])ores in trans\ trse 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 tieated with concentrated sulphuric acid. 



9. With a few retractile 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]; "& thread 



also appears at the end opposite the polar vesicles." 

 12-13. Free capsules and filaments, after treatment with concentrated sulphuric 

 acid. 



14. Calcareous bodies found in the abnormal tissue, associated with the M. 



lintoni. X 200. 



15. Three of the same, with a few spores. Sketch from material after action of 



potassic hydrate. X 400. 



16. Spores in aitu: («) nests of spores; (&) section of blood capillary; (c) con- 



nective tissue. Sketch made from a section of decalcified abnormal tissue.

la. Vertical view of spore, showing capsules and sporoplasm, the latter con- 

 taining a vacuole and 4 nuclei, 2 of them being the pericoruual. 

 16. 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. Myxobolus sp. 56 (original). Vertical views of spores, showing capsules 

 aad sporoplasm, the latter with the vacuole.
