While blastoderms in the early cleavage stages show considerable variation, cleavage in these eggs may in general be said to proceed very regularly. The majority of the blastoderms observed in the 4-cell stage were almost ideally symmetrical. The same may be said of many of the blastoderms of 8 cells. At this stage irregularities are not uncommon, however. A marked tendency toward regularity is apparent also in blasto-.
