NOTES ON SPOROZOA. 
239 
Fig. 3.— A free individual, wliicli has not yet penetrated a blood- 
corpuscle. 
Figs. 9-18. — Older forms, with the nucleus in the later phase, situated 
(except in fig. 14) near one end of the body. 
Figs. 14 and 15. — U-shaped forms. 
Figs. 16-18. — Stout, bean-like individuals, resulting from the fusion 
of the two arms of the U. In figs. 17 and 18 the cytoplasm of the 
host-cell is not visible, and the host-cell nucleus forms a “ cap ” round 
one or both ends of the parasite. 
[Figs. 19-43 are from wet films, stained with iron-hsematoxylin.] 
Fig. 23. — Uninfected red blood-corpuscle. 
Figs. 19-22, 24-29. — Younger parasites, showing the karyosome (or 
else two karyosomes) closely associated with the nucleus. 
Fig. 20. — Individual showing the promitotic division of the karyo- 
some, the two halves being still connected by a spindle. 
Fig. 21. — Small, free individual. 
Figs. 30-40. — Older individuals, with the nucleiis near one end of the 
body. In figs. 31, 37, a karyosome is still associated with the nucleus. 
Figs. 32-36. — Parasites showing different stages in the alteration 
and gradual disappearance of the unused karyosomatic material. 
Figs. 30, 39 and 40. — Individuals showing no sign of the karyosome 
or its remains. 
Figs. 37 and 38. — Individuals sxirrounded by a distinct envelope, and 
in connection with which nothing whatever can be seen of the cyto- 
plasm of the host-cell. 
Figs. 41-43. — Merozoites or very young schizonts of “Adelea 
ovata” (Barrouxia alpina, according to Schellack and Reichenow). 
Fig. 41. — A single large karyosome is present. 
Fig. 42. — The karyosome has divided into two by a promitotic 
division, the connecting fibril being still present. 
Fig. 43. — Four karyosomes of unequal size are present, resulting 
from further division. 
PLATE 10. 
[All the drawings are magnified 2000 times linear. I am indebted to 
Miss Rhodes for kindly drawing figs. 4 and 7. Figs. 4-10 are from 
Giemsa-stained smears ; all the othei’s from iron-hsematoxylin stained 
films.] 
Figs. 1-3. — Merozoites or very young schizonts of ‘‘Adelea ovata”
