Tlie innermost tooth on either side, and at times the one next to it, can e\-en now and again be entirely effaced, so that only two abcauline teeth can be distinguished on either side. — The proximal sarco- theca also varies considerably, diverging now more, now less wideh' from the hydrotheca, and having a free portion of varying length. The basal internodium of the hydrocladium has a different structure owing to the position of its proximal sarcotheca. This is shifted to the obliquely upward trending hydrocladium, — the side away from the stem — and is also somewhat smaller than on the following internodia. The cause of this must be sought in the growth of the phylactogonium. The phylactogonium (fig. XL ff) is segmented and has only hydrothecae on two of its branches; on one of them at times two, but as a rule onlv one on each; thev are surrounded bv the usual three.
