Figs. 27, 28.—Pyriform bodies of T. rhodesiense and T. gambiense 
(fig. 28) from peripheral blood of guinea-pig. In fig. 28 
the flagellum is shown beginning to develop. 
Figs. 29, 30.—Two pyriform non-fiagellate forms from spleen of 
rat. 
Fig. 31.—Round form of T. gambiense , with nucleus, blepharcplast 
and short flagellum along the edge of the body; from 
peripheral blood of rat. 
Figs. 32-40.—Crithidia-like forms. Fig. 32, of T. gambiense from 
blood of rat; figs. 33-35, of T. rhodesiense from lung 
(fig. 33) and peripheral blood of rat; figs. 36*38, °i 
T. gambiense from blood of guinea-pigs; figs. 39 _ 4 °> °F 
T. rhodesiense from blood of guinea-pigs. In fig. 37 
note the basal granule (‘ blepharoplast ’ of Minchin) at 
the root of the flagellum, forming the centrosome of the 
kinetonucleus. 
Fig. 41 represents an almost trypaniform stage of T. gambiense 
from blood of guinea-pig. Note the peculiar position 
of the blepharoplast (kinetonucleus). 
Fig. 42 represents a stout trypaniform parasite from heart blood 
of rat. 
Fig. 43 shows peculiar, large rounding form (lrom blood of a rat), 
exhibiting signs of division of its nucleus an 
blepharoplast. 
Figs. 44, 45.—Slightly irregular parasites, very pale staining and 
vacuolated. Degenerating, as seen in detachment o 
flagellum, etc. 
[s. 46-49. — Degenerating trypanosomes, exhibiting chromatoly 
all from lungs of rats. Fig. 46 of T - intense, 
magnified 1,350. 
Fig. 50.—Degenerating Trypanosoma gambiense , showing vacuo 
lain, pale-staining cytoplasm and begrnnmg of 
disintegration.
