these granules we can say nothing certain. Granules of similar 
appearance sometimes occur in much smaller numbers in mikrogame- 
tocytes. 
A few rounded forms (fig. 31) are present in which the host-cell 
nucleus has been extruded and the ectoplasm thrown off. These are 
possibly parasites prepared for fertilization.' 1 Nothing was ascer¬ 
tained concerning the nuclear changes at this stage.* Such parasites 
measure about 14/z by 9/z. 
Adult whet-stone-shaped parasites occur (fig. 70) which possess 
general characters intermediate between the male and female adult 
types described. They are, therefore, not readily referable to either 
sex ; but our material does not permit an assertion as to whether an 
indifferent form exists or not. 
Adult Male forms. 
Besides the forms in which the line occurs or is developing (fig. 3 T 
there are other parasites where the nuclear material follows a 
development of different type (figs. 48, 52) ; it is impossible to say 
definitely whether there is any connection between these two 
processes. 
Apparently an early stage of this second process is illustrated m 
figs. 48, 70, 71, 75. There is more or less diffuse and abundant 
chlamydoplasm. In the chlamydoplasm occurs a denser, at first circular 
or spherical, mass of chromatin—the “ nucleus.” (It may rarely be 
placed just outside the chlamydoplasm.) Outside of the chlamydo- 
plasm, but occasionally in connection with a detached portion of it, 
is a second denser mass of chromatin— the “ blepharoplast." The 
blepharoplast is identified by its granular nature and by its darker 
staining. 1 he nuclear material becomes arranged in a thick semi¬ 
circular arc (figs. 49, 76.) At its centre usually occurs a dot, often 
connected with the extremities of the arc by fine lines (figs. 53 - 55 ) 
The arc of chromatin becomes hemispherical and the dot increases in 
size (figs. 50, 52) until the place of the nucleus is taken by two 
irregularly oval chromatin masses of approximately equal size (fig- 5 1 ) 
A stage preliminary to this process is possibly illustrated in fig- 47 ' 
where four brownish granules, of quite a different colour from the 
chromatin granules of the blepharoplast, occur in close connection 
* l he line in the nucleus of fig. 31 makes it very doubtful to what stage this 
parasite really belongs.
