    Fig. 32. Prophase with division of the centroblepharoplast completed in the tubular part but no split yet appearing in the ectoplasmic structures. An unusual figure. X 300. Fig. 33. Splitting of the centroblepharoplast and the formation of the paradesmose between the bases as they separate. Fig. 34. <A later stage of the same with the halves forming new tubes con- nected at the tip. Note development of spines at tip. Fig. 35. An earlier stage of the same showing the split beginning at the base, with the ectoplasmiec structures drawing apart. Fig. 36. Splitting completed; paradesmose elongates as the new centro- blepharoplasts move apart. Fig. 37. Vertical view of an early stage of splitting of centroblepharoplast. Fig. 38. Vertical view of individual in prophase with the divided centro- blepharoplasts connected by paradesmose. Part of oblique fibers and alveolar layer shown. Note aster arrangement of alveoli around centroblepharoplasts. x 300. Fig. 39. Prophase nucleus showing the breaking up of the chromatin- encrusted network. Fig. 40. Paradesmose, centroblepharoplasts and their related fibers in the prophase, with the nucleus elongating preparatory to formation of mitotic spindle. [90]
