The egg is shown in its natural position with respect to the verticalaxis, which passes in the plane of the paper parallel to its lateral margins. Theembryo proper has a total length of about 155 degrees. This figure and figure166 are drawn from the same egg. survey of the earlier work on the segmentation of the vertebratehead is given by Locy (95).

This figure and figure166 are drawn from the same egg. survey of the earlier work on the segmentation of the vertebratehead is given by Locy (95). Ishikawa (08) has described seg-mental divisions in the open neural plate of Cryptobranchusjaponicus. During this stage, if not already in the preceding stage, theanterior or dorsal part of the blastopore becomes closed over,while the ventral part persists as a transverse crescentic slit(figs. 177 and 178). At the close of Stage 14 the embryo hasincreased slightly in length (fig. 179); it now extends over about155 degrees of the surface of the egg. This increase in length EMBRYOLOGY OF CRYPTOBRANCHUS 515.
