Plate XXI 
With the exception of fig. 38, probably a female, all the parasites 
illustrated in this plate are males. 
Fig- 33 -—Division of the line; nucleus only just commencing to 
divide. 
Fig- 33 a - —Division of line with chlamydoplasm and nucleus. The 
ectoplasm has been deleted for convenience of reproduc¬ 
tion. 
Fig- 34 -— Formation of line (?). Note the presence of granules of 
chromatin. 
Fig- 55 -— A very common form (see figs. 42, 43, 74). It represents 
the line passing through a diffuse chromatic area 
(chlamydoplasm) in which lies a denser chromatic area 
(nucleus ?), often containing one or more (figs. 42, 41) 
deeply chromatic granules (blepharoplast ?). Occasionally 
these granules, or similar ones, lie outside the denser 
nuclear material (fig. 43). 
Fig- 3^. — Degenerated and squashed parasite, showing multiple 
nature of line. 
Fig- 3 7 - — Only three parasites of this type (all practically identical) 
were seen. It is remarkable in possessing a blepharoplast- 
like mass of chromatin distinct from the main nuclear 
structure. 1 here is an indefinite arrangement of fibrillae 
an d granules about the nucleus and chlamydoplasm. 
F'g- 38- A female cell (unique), in which a faint blue line was wound 
spirally about one half of the line. Appearances 
resembling this were seen in one or two other preparations 
(fig. 62). 
F’g- 39 - Fine dividing longitudinally, nucleus already completely 
divided. Parasites of a similar type are not infrequent. 
The one illustrated is considerably distorted. 
I H1 gs. 40 and 41. — Commencing transverse division of the line. In 
each parasite the line has become thinner. In fig. 41 the 
differentiated area surrounding the constriction is well 
seen. 
Figs. 42, 43 and 74. — Are ordinary types of adult males with lines. 
rigs. 41, 42 and 43 — Blepharoplastic (?) granules occur in the two 
former within, in the latter without, the nucleus. The 
presence in fig. 43 of a bluish area within the chlamydo¬ 
plasm in immediate connection with the nucleus is 
suggestive. 
Fig- 44 - The line is divided transversely (specimen unique); the 
two halves are connected by a filament. 
45 - (Compare figs. 63 and 64). Probably represents a stage 
Fi r ant enor 46 . (Specimen unique.) 
g. 40. l he fine is much involuted. It extends far into the 
ectoplasm. A faint blue spiral line (artefact ?) extends, 
liom a double granule in the ectoplasm, through the lower 
part of the parasite. The arrangement of the nucleus is 
not at all definite.
