    ceUs, showing one segment the form of the germ-cell, the other, ordinary vegetative division supervening, having assumed that characteristic of the species. 61. Euastrum didelta (Ealfs), X150, abnormal condition of, after W. Archer (Nat. Hist. Eeview, vi. p. 469), showing a central irregular structiu-o produced between the original segments, apparently owing to the non-formation of a septum on the resumption of vegetative growth, and forming with them but one uninterrupted cavity; and in this instance the new central growth having assumed the size and nearly the form of an entii-e frond, its axis of growth and plane of expansion are at right angles to the old segments. 62. Artlirodesmus Incus (Hass.), X300, abnormal condition of, after W. Ai-cher, I.e., showing an abnormal growth analogous to preceding, but carried on to another vegetative generation, the middle portion being older than those produced between it and the original segments, the whole still forming within but one uninterrupted cavity. 63.
