“centrosome” (cezé.) as marked, Billet’s stain followed by tannin orange. 
x 1000. 
Fra. 23.—Attenuate form, apparently young, as division stages, and many 
attenuate parasites occur in this preparation. Membrane probably closely 
attached to body, only clearly seen at one point. In this, and the parasite 
sketched in the preceding (fig. 22), the thinner chromatin rodlets are probably 
at_a deeper focus. Leishman’s stain. xX 1500. 
PLATE 2 (Ricut Hater). 
Fies. 24, 25, 26.—Spirillar forms from hind gut of cockroach, 
with terminal flagella and diffuse (faintly spiral) nuclei. Gentian-violet. 
x 1500. 
Fic. 27.—Typical specimen of 8. anodonte, with spirally wound mem- 
brane, showing myoneme striations faintly, and in parts a spiral nuclear 
filament. There is a “basal granule” near the base of the fine process 
terminating the pointed ends of the body. Delafield’s Hematoxylin. x 2000. 
Fic. 28.—Parasite attached to débris at one end. Membrane only faintly 
stained, but chromatin rodlets clearly seen. Iron Heematox. and Orange G. 
(but the orange does not stain the parasite). x 1500. 
Fic. 29.—Specimen showing well marked spirally wound membrane and 
basal granules, but chromatin rodlets a little indistinct. Gentian-violet. 
x 1500. 
Fic. 30.—Preparation stained with Safranin and Licht-griin, but the latter 
stain did not colour the parasite. Membrane edge clearly stained, but 
chromatin thread indistinct. x 1000. 
Fic. 31.—Specimen stained in a manner similar to the last, but the chro- 
matin elements (rodlets) are brought out. Safr. and Licht-griin. x 1000. 
Fie. 32.— Rather broad specimen of 8. anodonte showing basal granules. 
Gentian-violet. x 1500. 
Fic. 33.—Parasite from crystalline style of Anodon, with coiled posterior- 
ally directed end characteristic of a slowly moving form, Edge of membrane 
seen at side of the coil. Safranin. x 500. 
Fic. 34.—Parasite with nucleus sharply stained, but membrane, which is 
close round the body, only faintly indicated. One end of .body, on left, 
rather rounded—from which a fine process starts. Gentian-violet. x 2000. 
PLATE 38 (Rieut Hatr). 
Fic. 35.—Parasite with one end curled, showing basal granules, membrane 
with myonemes, and chromatin rodlets. Billet’s stain and tannin orange. 
x 2000.
