Fig. 3. A portion of the intestine shewing the same. The 

 centrally placed' parasite is still a swelling, not 

 having yet become an appendage, x 1. 



Fig. 4. A section through a piece of the gut wall and an 

 appendage. The dotted line divides the two. 

 The darker shaded part (par.) is the " diffuse 

 infiltration," the lighter part representing un- 

 infected tissue, ep. is a thin layer of connective- 

 tissue and peritoneal epithelium covering the 

 appendage, cy. is a " pseudocyst." x 20. 



Fig. 5 is part of one of Johnstone's cysts (specimen A), and 



Fig. 6 is part of one of mine (B). For description, see the 

 text, 

 ect. = ectorind (ectoplasm), end. = endoplasm. 

 endothel. = a fold of the mucosa, shewing its 

 normal appearance, n, = large nuclei in 

 endoplasm. Pspbl. = various stages in 

 the development of spores (sp.) from the re- 

 productive organellas, x 500, Zs. 3mm. Apochr.

Fig. 7 (a). Spores from (A). 7 (/>). Spores from (B). N. 

 = nucleus of sporoplasm, p.c. = polar capsule, 

 x = nucleus of latter, s = suture, v = vacuole. 

 x 1,600. Zs. 2mm. Apochr. 1-40 O.I. C.E. 8. 



Fig. 7c. Fresh spores of Ghigea anomala, treated with 

 iodine sol. in 50% ale, one of which shews the 

 polar filament extruded, x 1,200. 



Fig. Id. Spores of Sphaerosyora platessce, one shewing 

 the 2 polar-filaments expelled. g = retractile 

 granules, x 900. Z. 3mm. Apo. 1'40 0.1.
