PLATE X. 



Fig. 1. Gorynocladu!, rndiatiis, from the ventriculus of Passalus cornutus. 



a. Trunk. 



b. Clavate branches. 



c. Investment of granular phytoid matter; sporular? 



d. Arthromitous filaments. 



Fig. 2. Extremity of a branch of Corynodadus, very highly magnified, exhibiting the manner in which 

 adhering matter appears dimly shaded, consisting, probably, of spores of the plant. 



Fig. 3. Three filaments of a doubtful nature, whether vegetable or part of the animal structure of the 

 ventriculus of Passalus cornutus, formerly called, by me, Crypiodesma tenuis. 



Fig. 4. Polyspore ? from the ventriculus of PoTydesmus granulatus, found mixed with the food. 



Fig. 5. Inferior portion of another individual from the same situation. 



Figs. 6, 7. Polysporcs? found mixed with the food in the ventriculus of Passalus cornutus. 



Fig. 8. Ergot, Ergotxtia dbortifaciens? found in the proventriculus of Acheta nigra. 



Figs. 9-12. In dead individuals of Julus marginatus, within the ventriculus and large intestine, I 

 frequently observed a fungus in the form of small, white, translucent, compressed, spheroidal bodies, growing 

 upon the mucous membrane, or upon dead filaments of Enterohryus lying upon the mucous membrane. The 

 centre of these bodies was depressed, and the surface covered with fine longitudinal striae, intersected by 

 short transverse stria3. By reflected light, thoy resembled minute bleached shells of Echini. They measured 

 from the 755^ to the -jij, of an inch broad. Upon pressure, they burst or dehisced into several leaf-like 

 finely-striated lobes, and exuded a clear but faintly granular liquid. 



Fig. 9. Two of the fungous bodies, just described, viewed by reflected light. 



Fig. 10. A group of the same bodies growing upon a filament of Enterohryus, also viewed by reflected 

 light. 



Fig. 11. One of these bodies viewed by transmitted light. 



Fig. 12. One of these bodies burst into six leaf-like lobes from pressure. 



Fig. 13. A polyspore? from the large intestine of Julus marginatus. 



Figs. 14-21. Fungous sporuli, in various stages of development, found in the fecal contents of the large 

 intestine of Salamandra erythronota, S. salmonea, Triton niger, etc. They are probably found in the cloaca 

 of all the Salamanders. 



Fig. 14. Much more highly magnified than the others. 



Figs. 18, 20, 21. In outline. 



Figs. 14-17, 19. 

 a. Granular matter. 

 I). Transparent liquid. 



Fig. 22. Fungus mycelium, found growing in the cloaca of Triton niger. 



a. Colorless liquid. 



b. Granular contents. 



c. Nuclei. 



d. Phytoid filaments, at the basis of which was a quantity of adherent granular matter. 

 The small isolated lines represent a species of Bacterium, which existed in vast numbers. 



Fig. 23. Fungus developed from the spores of Figs. 14-21, and the mycelium, Fig. 22, upon the dung 

 of Salamanders when exposed to the external air. A species of Torula, or perhaps Briarea? 



a. Spores. 



b. Spores in outline. 



c. Receptacle. 



d. Mycelium. 



Fig. 24. Portion of mycelium, with contained spores, of the same fungus as Fig. 23. 

 a. Spore. 



h. Spore in outline. 

 '. Mycelium.
