The mesoderm is here now divided into two layers, x 387. at the anterior end of the germ band and progresses backward, following the rule for arthropods in general.

The mesoderm is here now divided into two layers, x 387. at the anterior end of the germ band and progresses backward, following the rule for arthropods in general. Figure 22A il- lustrates a median sagittal section of Stage V through that por- tion of the middle plate lying just behind the anterior mesenteron rudiment. Four segments are very plainly visible, much more so than is usual. Figure 22B is taken from the same series and passes laterad of the median plane through one of the lateral plates. It shows very distinctly the segmentation of the future ectoderm, four segments being also represented. The segments are not however always sharply marked off from one another in either the lateral or median plates and are frequently somewhat irregular. After the middle plate becomes overlaid by ectoderm its lateral.
