as food material in the growth of the blepharoplasts and other parts 
of the cell. During the telophase the blepharoplast is represented by 
a more or ess irregular or spherical mass of granules, which have evi- 
dently been derived by the breaking up of the membrane. ‘‘It would 
seem that the outer membrane of the blepharoplast breaks up into 
numerous segments or granules, which assume a roundish or elliptical 
form, and through the action of the cytoplasm become crowded to- 
gether in a mass occupying the position of the original blepharoplast.” 
About the time of the reconstruction of the daughter-nuclei and the 
formation of the plasma membranes separating the cells, the develop-

the band of blepharoplast is being formedsby fusion of granules,

C, formation of ciliferous band by fusion of granules, more highly magnified. 
ment of the band, which is to bear the cilia, begins. It appears first 
as a short, delicate, and deeply staining line extending from the mass 
of granules toward the nucleus (Fig. 63, A). A little later a similar 
line or band can be seen on the opposite side of the mass of granules. 
From Fig. 63, B, it is apparent that the band is developed more or 
less directly from the granules. The band, which at first is very nar- 
row, increases appreciably in width (Fig. 63, B, C). The further 
development of the band with its cilia and the transformation of the 
daughter-cell into a spermatozoid closely resembles that of Cycas, 
already discussed at some length in the preceding pages, with the very 
noteworthy exception that in Zama there is no nuclear beak formed,
