IX , text Fig. 3, shows twenty-five mesenteries, eight of which he considers to be of the first cycle (mesenteries marked a) while of the re- maining seventeen six are according to his statement of the second cycle (marked b~) and the remainder of a third cycle. It will be noticed that several of the mesenteries in this figure- one pair of those marked Rm and the longest ones at one end of the figure—are very broad in section with a thick mass of endo- derm extending far beyond the mesoglea. None of the entire number of mesenteries have any trace of mesenteric filaments, nor by their structure, in so far as it can be made out from the original figures, is there any indication that they contain actively.
