Fig. I.— T. loricatum. This is apparently an ordinary division form 
with two blepharoplasts, two nuclei and two flagella. The 
nuclei are long, sharply-defined sacs, with many small 
chromatin granules in them. 
Fig. 2.— T. loricatum This form has a long nucleus with chromatin 
massed near both ends. There are longitudinal pleats 
and a short free undulating membrane. 
Fig. 3. — T. loricatum. This form has a round nucleus. The longi¬ 
tudinal pleats are present. 
Fig. 4. — T. loricatum. This form has deep longitudinal pleats. The 
nucleus is not so long as in figs. 1 and 2, but has the 
characteristic shape and curves towards the undulating 
membrane. 
Fig. 5.— T. loricatum. Lanceolate form. The nucleus is a long and 
broad band. The undulating membrane runs as a white 
band in folds down the middle of the parasite. 
Fig. 6.— T. loricatum. Long “ hyla form” (page 324). The body 
has longitudinal folds. The nucleus is long, and wide 
near the middle, tapering to both extremities. 
Fig. 7. — T. loricatum. Long “ hyla form.” The folds are unfolding 
No nucleus is visible. 
Fig. 8.— T. loricatum. Parasite has become rounded and is about 
to lose its flagellum. 
Fig- 45- — Trypanosome of the tortoise, showing round unstained 
areas. 
Fig. 46.—Drepanidia of the tortoise. The nucleus stains purple and 
both it and the cytoplasm are denser than in fig. 4 ^- 
Fig- 47 - — Drepanidium of the tortoise. The nucleus is red and the 
body has many coarse granules in it. 
Fig. 48.—Drepanidium of the tortoise. The nucleus is red ar.d 
loosely woven, and the cytoplasm is also loosely woven. 
Fig- 49 - — Drepanidium of the crocodile. 
big- 5 °- — Drepanidium of the snake—common form. 
Fig- 5 1 - — Drepanidium of the snake. The nucleus and cytopL- 
are loosely woven, and vacuoles are present at both en - 
Fig- 5 2 -—Drepanidium of the snake, showing elongation of the bod} 
of the host-cell. 
Fig- 53 - — A curious appearance in a snake’s blood (page 304); lre ' 
form, red dot in the middle. 
big- 54 - The same in a cell with no drepanidium. 
big- 55 - — The unidentified parasite of the snake—round form.
