5&. 'J'ransverse view. 



6. Spores (original). 



Oa. Broadest forui, sliowiug. in the sporoplasm, the central tongue-shaped 

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

 Gentian violet; slightly iliagraniniatic. 



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 first and second series of nucleiform bodies. 

 Hydrochloric acid alcohol carmine. 



Gd. N.arrow form, showing the 3 series of nucleiform "l»odies and posteriorly an 

 Tinusual appearance. Hydrochloric acid alcohol carmine. 



6e. Transverse view of spore, showing equality of valves and relative width of 

 ridge (ridge index). 

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

 sules' and sporojjlasm, tiie latter with vacuole aud 4 nuclei (2 of them the 

 pericornual). Hydrochloric acid alcohol carmine. 



Plate 27.

1. Ciiprinodou raric(i<iti(t<, with excrescences caused by this species; one on 



i-igiit 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 



retractile globular masses near the posterior end. 

 4. Spore treated with osniic 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 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" [? shrnnken 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. Calcareous bodies found in the abnormal tissue, associated with the M. 



livtoni. X 200. 



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



potassic hydrate. X 100. 



16. Spores in silu: (a) nests of spores; (h) section of blood capillary; (c) con- 



nective tissue. Sketch made from a section of decalcified abuoi-mal tissue.

the wide ridge.
