The “ chlamydoplasm ” is a diffuse, light-purple-staining area 
whose outlines, though very irregular, are, nevertheless, usually 
definite. In the female parasites (figs. 66, 67, 72, 73) and in males 
with lines (figs. 33-46) it is comparatively compact. In older 
mikrogametocytes its mass becomes greatly increased (figs. 50-5(0) 
and its outline is less definite (figs. 58, 61). It may lie compactly 
about the nucleus or stretched out (fig. 76) and distributed in any 
way through the endoplasm. If it is divided, one part remains with 
the nudeus, the other is about, or near, the blepharoplast (Fig. 50). 
The “ nucleus ” is employed as an indefinite term to designate 
the denser collection of chromatin enclosed in the chlamydoplasm. Its 
shape varies considerably ; possibly its nature does so also. 
The “ blepharoplast ” is the term applied to a very deeply staining 
collection of chromatin usually occurring quite alone in the endoplasm, 
and showing a distinctly granular structure (figs. 3 » 55 ’ 4 ^)- 
younger parasites (figs. 3, 5) on ly two *-° f° ur granules, arranged 
in pairs, can be counted. In the older parasites (figs. 68, 7 1 ) the 
blepharoplast consists of one central granule and from six to eight 
other granules joined together by fine lines and situated about the 
periphery of the sphere of translucent chromatophilic material in 
which they are placed, and outside the chlamydoplasm. As a rule, 
no blepharoplast-like body exists separate from the nucleus in 
parasites which show the line formation; rarely one is present 
(%• 37 ). In such parasites the line seems to have split at the end 
opposite to that at which the free blepharoplast is placed. This 
“blepharoplast” is probably formed by division of the ‘‘nuclear” 
mass of chromatin. An oval non-staining or more lightly staining 
area, the “ vacuole,” is very constantly associated with the blepharo¬ 
plast in parasites of all ages. It may vary greatly in size (figs. 53 > 73 )- 
"Dots,” or chromatic granules similar to those illustrated in figs. 15- 
! 9 , 2 3 - 47 , 59 , were seen in a few instances. They occur in parasites 
°f all sexes and sizes in any position. It is impossible to say anythin^ 
concerning their function from our specimens. In one parasite of 
the type illustrated in fig. 71 a chain of five pairs of granules, arranged 
' n a column, occurred within the chlamydoplasm and in immediate 
connection with the nucleus. In the same way a column of three 
P air s of granules has been seen placed beside the blepharoplast. n 
0ne or two cases a pair of granules was joined by a fine thread.
